Subject: [Pythonmac-SIG] py2app + pygame: how to exclude pygame icon?
Message-ID: <8BC4EC6F-FFAE-4E5A-A389-B866E00B44A0@yahoo.com>

Hi all,

Am using py2app and hitting this problem: py2app's built-in recipe for  
pygame is causing the pygame icon to appear when I run the app from  
the dock.

It goes something like this:
	1) The icon file I provide for my app appears in the dock by default,  
thanks to python setup.py py2app --iconfile my_icon.icns.
	2) However, when I click on that icon in the dock, it briefly changes  
to the pygame icon (snake with game controller in mouth) and bounces  
up and down, before my app runs.
	3) I tried adding a call at the start of my app to  
pygame.display.set_icon() to override the pygame icon with my own icon  
-- this causes the bouncing pygame icon to change back to my app's  
icon immediately before my app takes over the screen. However, I still  
see the pygame icon for a moment or two.

This may sound like a small issue, but I'm about to submit the app for  
testing to a "serious" client, and I know they would not appreciate  
the pygame icon.

So, is there a way to either:
	1) Exclude pygame_icon.icns on the command line (I tried --excludes  
and --dylib-excludes to no avail); or
	2) Change the default recipe for pygame;
	3) Invoke some other magic to fix this?

BTW: I also tried to remove pygame_icon.icns manually after the app  
was created (deleting it from site-packages.zip, then recreating  
the ..zip file), but this broke something else.

TIA...!

Happy holidays,
Joel

Could you not just replace the pygame icon with your icon?
So still have a file named pygame_icon.icns, but the contents would be
your icon?

Hi Chris,

Thanks for the suggestion!

I actually tried it earlier, by opening site-packages.zip, replacing  
the icon with one of the same name (but my own design) and recreating  
the .zip -- unfortunately, it broke the app (refused to run, with an  
odd error).

I also looked for a way I could replace the original pygame_icon.icns,  
which I tracked down to somewhere inside the python.framework file --  
I tried to delete or replace it, but kept getting an error that I did  
not have permission (even though I'm the admin login, and even went to  
program info and changed the permissions there to let everyone write  
the file!)

So: I'm still stuck -- any other ideas would be MOST welcome!

Thanks for trying,
Joel

Subject: [Pythonmac-SIG] py2app which version ?
Message-ID: <1isxhr3.1a2yfbxl3q6xeN%pdorange@mac.com>

Hi,

I just update my system (MacOS X 10.5) and now i got the default python
2.5.2.
My software (a little game using pygame 1.8.1) works fine but when i
create a bundle with py2app, the application crash at launch...

I install the trunk i used before (0.4.2) but the application still
crash.

Looking on internet i found several py2app and i don't what to use...

On the official site : 

official site : py2app 0.1.8 :
http://undefined.org/python/py2app.html#downloads

py2app 0.4.2 : 
http://svn.pythonmac.org/py2app/py2app/trunk/

py2App 0.3 : 
http://svn.red-bean.com/bob/py2app/trunk/

I don't know which is the best and how install it.

Before going to MacOS 10.5 i used 10.4 and i install myself Python 2.5,
pygame 1.8 and py2app 0.4.2. It was working fine with this
environnement.
How can i do now with 10.5, may i install a personal python 2.5.2 or
it's better to use the default system one (2.5.2 also)...

Hello and happy new year!

I'm new to python and to this list but am a happy several year convert  
to OS X (now using leopard).

I hope this isn't some kind of noob question that upsets the  
subscribers to this list :-)

I realize that leopard ships with its own python installation but that  
it is somewhat outdated compared to what's currently available (the  
latest being python 3.0). Not long ago, I installed, I believe,  
MacPython (ver. 2.5). At least when I enter "which python" I get:

Macintosh-4:~ gary$ which python
/usr/bin/python

and when I enter "python" from within my home directory, I get:

Macintosh-4:~ gary$ python
Python 2.5.1 (r251:54863, Jan 17 2008, 19:35:17)
[GCC 4.0.1 (Apple Inc. build 5465)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
 >>>

But suppose I want to install version 2.6 or the newly released 3.0;  
where do they get installed (will they overwrite previous  
installations) and if they occupy their own territory, how do I run  
the various versions? I assume each separate version has its own  
version of IDLE too...

Is there some way of finding out which pythons I have currently  
installed and their locations (paths?)

Thanks for your help,
Gary

Hi Bob,

Thanks for pointing me to the right place -- I was able to replace the  
pygame icon with my own as a temporary fix.

I have two more questions (I know, you're not supporting py2app  
anymore, but you're basically the guru of this code so I thought I'd  
at least try to go directly to the source...!):

1) My built .app is missing frameworks pygame depends on. I'm trying  
to include them by using py2app's "frameworks" option, but it doesn't  
seem to work as advertised -- no matter how many ways I devise to give  
it a "comma-separated list of additional frameworks", it only adds the  
first framework in the list. (This is true whether from the command  
line or within the setup file as a py2app option.) Using the  
frameworks option multiple times does not seem to work. Is there a  
secret method? Currently I'm doing:

APP = ['savi.py']
DATA_FILES = ['../gameplay', 'data', 'en']
OPTIONS = {	'argv_emulation': True,
		"iconfile": "mac_savi_icon.icns",
		"dist_dir":"mac_dist",
		"bdist_base":"mac_build",
  		"frameworks": ["SDL_image.framework", "SDL_ttf.framework",  
"SDL_mixer.framework", "SDL.framework"],
		"includes":["Numeric"]	}

setup(	app=APP,
	data_files=DATA_FILES,
	options={'py2app': OPTIONS},
	setup_requires=['py2app'],
	version="0.2.3" )

2) When I run "python setup.py py2app", it seems to run fine for a  
while but then hits a snag -- here's a traceback:

I've tried using the debugger to determine what's going on but it

Thanks for any help you're willing to provide -- from your sunny  
retirement as py2app maintainer!

Unknown load command: 27 means it's seeing a load command (low level
Mach-O stuff) that it doesn't understand, which is reasonable because
I don't think I've updated the code since 10.4 or so and there are
probably some new ones.

I only really worked on py2app, etc.when I was building Mac apps, and
I haven't in a few years. I spend my open source time working on more
server-side stuff.

Thanks, Bob -- and any idea why the frameworks are not adding as they  
should?

One other question that should be easier to answer:
I located the py2app source code on my machine, and tried to slightly  
modify it. How do I get my modified version to run when calling  
"python setup.py py2app"? (without having to duplicate the entire  
py2app package?)

There have been some fixes for similar issues -- make sure you re using 
the latest py2app:

easy_install py2app==dev


(I think that's the call...)

Hi all --

It seems I have solved my frameworks problem for now -- I simply  
copied all the frameworks I needed and manually stuck them inside my  
app (deleting all the unnecessary header folders). Not an automated  
process, but at least my python app now seems to run on other Macs.

Also, I solved the pygame_icon problem by changing permissions (sudo  
chmod 777) on the "pygame" folder inside python.framework and  
overwriting pygame_icon.icns and pygame_icon.tiff (the .tiff file was  
the real culprit, I discovered) with my own version (same filenames,  
different contents).

Thank you, Chris VB, Tom W, and Bob I!

I think that just means that you have to install modulegraph==dev on its own.

You're right, could have thought of that myself. Sorry for the noise.

Thanks DavidW for the very informative link!

I think my python installations may be a bit "wonky." Here's what I  
get when I enter:

Macintosh-4:~ gary$ ls -l /Library/Frameworks/Python.framework/Versions/
total 8
drwxr-xr-x   7 root  wheel  238 Mar 11  2008 2.3
drwxr-xr-x  11 root  wheel  374 Mar 11  2008 2.5
drwxrwxr-x  10 root  wheel  340 Oct  1 16:52 2.6
lrwxr-xr-x   1 root  wheel    3 Dec 28 17:19 Current -> 2.6

and what I get when I enter:

Macintosh-4:~ gary$ ls -l /System/Library/Frameworks/Python.framework/ 
Versions/
total 8
drwxr-xr-x   7 root  wheel  238 Mar 11  2008 2.3
drwxr-xr-x  11 root  wheel  374 Mar 11  2008 2.5
drwxrwxr-x  10 root  wheel  340 Oct  1 16:52 2.6
lrwxr-xr-x   1 root  wheel    3 Dec 28 17:19 Current -> 2.6

It appears to me that these are identical, though the /System/Library/  
directory is supposed to be where Apple installs it's apps. Some how I  
must have done something kinda screwy.

Also, it's puzzling to me that "Current" in both cases is linked to  
2.6, yet when I enter "python" from my home directory, I'm getting  
Python 2.5.1.

Last puzzlement, When I enter "python" from my home directory, how  
does it know which python to reference? There must be some way it  
chooses one python over another.

What's the best way to sort my seemingly confused system out?

Thanks much again,
Gary

that looks ok. It's possible to maintain more than one version  
simultaneously.
Then if you wanted to use v2.5 you just change the Current  symlink to  
that in the Versions dir, as above.
Note that each version has its own 3rd party packages directory. I'm  
using 2.5 so for me it is at
/Library/Frameworks/Python.framework/Versions/Current/lib/python2.5/ 
site-packages/

This is where the apple distributed directories are.
Not sure why. Perhaps you;ve kept them (up to 2.5.1, I think) as a  
result of OS upgrades.

I think most macpython users don't use them, unless you're  
specifically needing to check that something runs on a default sys.  
setup,
preferring, instead,  to use those in /Library/Frameworks/ 
Python.framework/Versions/.

Perhaps. I don't think apple has distributed a v2.6 yet.

My guess is that it's loading the apple distributed one in System/ 
Library/Frameworks/Python.framework/Versions/2.5

try, at the unix prompt
% which python

You should also check whether there is a shell variable $PYTHONPATH --
% echo $PYTHONPATH

depending on the results of those queries, you can force it to use a  
particular one.
Say which shell you're using (bash?, sh? csh?)

Subject: [Pythonmac-SIG] Python App with py2app/pygame crash
Message-ID: <1it0nui.crpmzs1sub27oN%pdorange@mac.com>

Building a bundle application with py2app 0.4.2 it create an application
that crash at launch.

If a bundle a basic python script (no pygame) it seem to works fine.

My config :
        MacOS 10.5.6
        Python 2.5.2 (original came with MacOS)
        Pygame 1.8.1 rc1 ()
        py2app 0.4.2 (easy_install)

Few weeks ago with MacOS X 10.4 and a custom python 2.5.2 it works
perfectly...

Can't figure out why it crash now, bellow the bug report :

Hi Chris,

Thanks for this suggestion.

Question: when I ran easy_install for py2app as you suggested, it  
returned an error:

The required version of setuptools (>=0.6c9) is not available, and
can't be installed while this script is running. Please install
  a more recent version first, using 'easy_install -U setuptools'.

When I tried to install setuptools as it recommended, it seemed to work,
but then running easy_install for py2app again bombed in the same way.
(Whole session below.)

Any idea what's going on?

TIA,
Joel

But now setuptools itself thinks it's already 0.6c9, so it hasn't 
updated anything.

here setuptools has put the easy_install script in your home dir, rather 
than the default script directory. For instance, easy_install is here:

/Library/Frameworks/Python.framework/Versions/Current/bin/easy_install

on my system. typing "which easy_install" may help you figure out what's 
getting used.

So:

I suspect you are having issues with multiple different copies of 
setuptools and/or python.

I'd make sure that you are using the python you think you are.

You might also want to clean out setuptools and re-installs -- I don't 
know of any way to do this automatically, but you can delete stuff from 
site-packages and ALSO from easy_install.pth

Take a look at how PATH is being set also:

echo $PATH

and look in your .bash_profile or wherever your shell PATH is being 
added to, so that's it's set up right for you.

This appears to be another instance of being bitten by the Apple Leopard 
Python sys.path misfeature.  In short, the Apple-supplied Python for 
10.5 ships with the older version of setuptools and, because of the 
order of directories on its sys.path, the older version is always found 
first.

Jack suggests a workaround in this thread:

<http://comments.gmane.org/gmane.comp.python.apple/13850>

So you could try putting a .pth hack for the newer setuptools into one 
of the directories on sys.path as he suggests.

I should add that this problem is new in 2.5.4; it does not occur in 
2.5.2. Also, I've seen it on two machines. (It's in a big application 
and I've not had time to track it down yet; for now I've just reverted 
to 2.5.2).

those are the py2app dependencies -- why in the world you'd get them in 
your cwd is beyond me.

When you say "my setup script" -- do you mean your setup.py that is 
supposed to build your app?

post it, and we'll see if there is anything weird about it.

I would think so, but I don't know why they are there at all.

Chris, here's the setup script (which I run in my cwd, containing the  
main program I'm creating an app out of, "savi.py"). TIA for your  
diagnosis, doc! -- Joel

import os
from setuptools import setup

print os.system(r'sudo rm -rf mac_build mac_dist savi_log.txt')		

APP = ['savi.py']
DATA_FILES = ['../gameplay', 'data', 'en']
OPTIONS = {	'argv_emulation': True,
		"iconfile": "icons/mac_savi_icon.icns",
		"dist_dir":"mac_dist",
		"bdist_base":"mac_build",
  		"frameworks": ["SDL_image.framework", "SDL_ttf.framework",  
"SDL_mixer.framework", "SDL.framework"],
		"includes":["Numeric"]	}

setup(	app=APP,
	data_files=DATA_FILES,
	options={'py2app': OPTIONS},
	setup_requires=['py2app'],
	version="0.2.3" )

print os.system(r'sudo rm -rf mac_dist/savi.app/Contents/Frameworks/ 
*.*')
print os.system(r'sudo cp -R mac_frameworks/*.* mac_dist/savi.app/ 
Contents/Frameworks')

A Couple of Notes on the Above:

1) The py2app "frameworks" option doesn't work for multiple items,  
which is why I end up copying the frameworks into the app manually at  
the end -- I keep a copy of them in a special folder...)

2) This script always bombs in setup() -- here's the error:
File "build/bdist.macosx-10.3-i386/egg/macholib/MachO.py", line 178,  
in load
     raise ValueError("Unknown load command: %d" % (cmd_load.cmd,))
ValueError: Unknown load command: 27
 > /Users/joel/Documents/OT Video Games/SAVI Learning Tool Prototype  
ver 2.3/build/bdist.macosx-10.3-i386/egg/macholib/MachO.py(178)load()
Perhaps it never gets to delete the eggs because it bombs? Although I  
do tell Pdb to "cont" and it seems to exit normally... -- Joel

that all looks pretty normal.

oh, you do run it as:

$python setup.py py2app

don't you?

If you're using the Python.org build of python, it's built against the  
10.4u SDK, so the apps you build should be portable to any 10.4  
machine, even if built on 10.5. What error are you encountering when  
you try to run the 10.5-built app on 10.4?

Subject: [Pythonmac-SIG] How to get setuptools to build a Universal Binary?
Message-ID: <496506CC.30708@strout.net>

I'm (still) trying to make a neatly packaged Python app that works on
both PPC and Intel Macs.  All is good except for mysqldb; following the
procedure I've documented at
<http://www.dotancohen.com/howto/python-app-mac.html>, my app bundle
contains an Intel-only binary of the mysqldb library
(libmysqlclient_r.16.dylib).

This page
(http://developer.apple.com/opensource/buildingopensourceuniversal.html)
at Apple suggests a possible solution: build separate Intel and PPC
binaries, and then combine them with lipo.  But of course that's using
Makefiles.  MySQLdb instead uses setuptools.

So: does anyone have a clue how I can convince setuptools to build a PPC
binary (or better yet, a Universal one) on an Intel machine?

This may or may not also be involved:
   <http://bugs.python.org/setuptools/issue19>

Any advice will be greatly appreciated...

setuptools using distutils to build, and distutils should build a 
Universal binary if you run it with a Universal Python (the python .org one)


> This may or may not also be involved:
>   <http://bugs.python.org/setuptools/issue19>

I don't think so. I think the issue there is with easy_install getting 
confused when you try to install a Universal binary.


> Any advice will be greatly appreciated...

I'm not familiar with MySQLDB, but there are two issues at hand when 
building Universal extensions:

1) making the extension Universal -- that SHOULD be taken care of by 
distutils.

2) making sure all the libs that the extension depends on are Universal 
-- you have to do this first, and it has nothing to do with setuptools, 
or distutils, or even python.

It looks like you have a libmysqlclient dependency -- which makes sense 
-- you need to find a way to get a Universal one of those.

That apple page you referenced should help guide you.

Best case:

If the lib source has been tweaked to be able to build universal, you 
may  be able to pass a flag like "universal" into configure, if you're 
really lucky, otherwise, sometimes passing in both arch=PPC and arch=x86 
or something like that can work.

Next best case:

You can pass in either PPC or x86 separately, building two versions and 
then lipo-ing them together.

Worst case:

Some code can only be built for the architecture the compiler is run on, 
due to how they detect endianess, etc. In this case you need to build 
one on PPC, and one on Intel, and then move them to the same machine to 
lipo them together.

The other complication is that you need to make sure to use the right 
SDK, if you want o build on 10.5 and allow it to run on 10.4.

Anyway, the short version is that I think you need to dig around the net 
for info on how to build libmysqlclient Universal -- hopefully someone 
has done it and distributes a binary, but presumably you've already 
looked for that.

One last note: usually, when folks want to distribute a python extension 
that depends on a lib that Apple does not provide, they build that lib 
statically, then link that version into their extension, so you don't 
have to worry about distributing it -- same issue with Universal, though.

I quick poking around tells me that MySQL themselves distribute Intel 
and PPC binaries separately -- I suspect you could get each of those, 
and pull the libs out and libo them together. This may be easier than 
building it yourself.

A couple helpful pages you've probably already found:

http://dev.mysql.com/downloads/mysql/5.1.html#macosx-dmg
http://developer.apple.com/internet/opensource/osdb.html
http://davidmichaelthompson.com/?p=12

I hope that helps,

-Chris

PS: I'm really surprised that no one seems to have done this already, 
and posted a binary egg or something! MySQLdb is not a minor package!

I just downloaded the mysqldb module from sourceforge to have a look  
at how it decides how to compile its C extension. It looks like it's  
getting the CFLAGS and LFLAGS from mysql_config. You'll need a  
universal binary of libmysqlclient (as Chris already pointed out). At  
any rate, you'll want to try to see what CFLAGS/LFLAGS were used to  
compile libmysqlclient. You might try to run the following command in  
terminal:

$ mysql_config --cflags

Which may shed some light on the situation. You'll be looking for  
something like this in the output:

  -arch ppc -arch i386

Which tells the compiler to include these architectures in the  
resulting binary. As Chris already mentioned, you'll also need a  
universal Python--I'm assuming you've already got that... Good luck.

That's how it seemed to me too.

This appears to be the problem, I think.

The only other extension involved, as far as I can tell, is wx, and that 
one is already universal.

That's what I'm trying to figure out how to do.  (libmysqlclient is the 
library behind MySQLdb, as far as I can tell.)

What is this "configure" you speak of?  MySQLdb doesn't use the 
configure/make dance which is standard for Unix libraries; it uses 
setuptools (which appears to be standard for Python libraries).  If it's 
using configure or make, it's doing so under the hood.  Any idea how I 
would specify universal or arch in this case?

Same question as above.

I suppose.

I gave up on that one a while back -- all this is being done on a 10.4 
(Intel) machine.  I can do it all again on a PPC machine if necessary.

This is exactly the question I was asking how to do.  But you seem to 
think that libmysqlclient is something other than MySQLdb.  I'm under 
the impression that it's the same thing.  The only other library in my 
"Frameworks" folder is libwx_macud-2.8.0.dylib, which I presume is 
wxPython.  (This one already is a universal binary.)

I think you're still imagining libmysqlclient as being something MySQLdb 
depends on, rather than the MySQLdb extension itself.

> and PPC binaries separately -- I suspect you could get each of those,

Maybe -- I got a UB of MySQL itself, so I don't think that's the 
problem.  (But of course it's entirely possible that I'm more confused 
than I realize.)

> PS: I'm really surprised that no one seems to have done this already,

No kidding!  I've spent more time futzing around with this than I have 
writing the app itself.  It's fairly ridiculous, and I'm now to the 
point where I have to seriously consider whether it's worth continuing 
this project in Python, or spend a day or two rewriting it in REALbasic.

I feel like I'm close, though -- if I can just figure out how to make a 
UB of this libmysqlclient thing, I think I'll be there.

Thanks,

P.S. While people have been very generous with their free help and 
advice, if anyone could be more motivated to spend a few hours on it as 
a paid consulting gig, I'd be happy to pay.

OK, but to be clear, libmysqlclient isn't something from somewhere else 
that mysqldb uses -- it's the C extension of mysqldb itself, right? 
Something built when I do "python setup.py install" in the mysqldb 
source directory?

Hmm, I don't see those.  If this were a makefile situation, I'd have 
some idea where to start poking further to find (or specify) these 
flags.  With setuptools, I haven't a clue -- what's the next step?  Is 
this something I can hack into setup.py, or what?

Yes, I do seem to.  And I can make an app (with py2app) that works fine 
on PPC and Intel Macs, as long as it doesn't use mysql.  So this appears 
to be the last part of the puzzle.

Thanks,
- Joe

libmysql is the library that PySQLdb depends on -- it is provided by 
MySQL -- it is NOT built by distutils -- it is only linked to.


> you seem to 
> think that libmysqlclient is something other than MySQLdb.  I'm under

nope -- I'm right -- libmysqlclient is just what you'd think __ it's the 
library for mysql clients -- provide by MySQL. I just confirmed this my 
downloading the installer from MySQL, and looking in and seeing what there:

$ file libmysqlclient.16.0.0.dylib

libmysqlclient.16.0.0.dylib: Mach-O dynamically linked shared library ppc


(I've got a PPC machine)

It looks like there is a static lib there, too.

So this is what I'd do:

get the dmg installer for both PPC and Intel for 10.4 from MySQL.

copy the intallers to your hard drive, and unpack Contents/Archive.pax.gz

poke around in there, and you'll find the dynlibs.

lipo the intel and ppc ones together, and presto!


Actually, I suppose what I'd do is install the native one on your build 
machine properly, and then use lipo to add the other one to the copy 
that's on that machine.

ouch, this does complicate things a bit -- as I have no idea how to get 
a "universal" mysql_config -- it may be telling distutils to build the 
extension with only one architecture.

nope -- see my other note.

the extensions that distutils builds will be called something like 
_mysql. It will be in site_packages, and in your app bundle, along with 
.py and .pyc files, NOT in with FrameWorks.


>> At any rate, you'll want to try to see what CFLAGS/LFLAGS were used to

here's mine:
$ /usr/local/mysql/bin/mysql_config --cflags
-I/usr/local/mysql/include  -g -Os -arch ppc -fno-common 
-D_P1003_1B_VISIBLE -DSIGNAL_WITH_VIO_CLOSE -DSIGNALS_DONT_BREAK_READ 
-DIGNORE_SIGHUP_SIGQUIT  -DDONT_DECLARE_CXA_PURE_VIRTUAL

Darn -- there is an "-arch ppc" in there. However, it may be that 
distutils still add the "arch i386" who knows?

if you get it to build, you can then look at what it builds, and see if 
that's Universal or not:

$ file name_of_lib

You can find what it builds in the "build" directory that distutils 
creates when you run "setup.py build". It will be in something like:

build/lib.macosx-10.3-ppc-2.5

and I think will be called -mysql.so

but I don't actually have it building here.

I suppose I should try -- now that I've gone this far!

if it doesn't, you can probably add it yourself with a small edit to

libmysqlclient is part of the MySQL distribution, i.e. not specific to 
python, so setuptools isn't the problem here.

It looks like there is an open feature request for the MySQL prebuilt 
packages to be built as universal libraries.   The submitter includes a 
recipe for doing it yourself.  I haven't tried it myself, though.

<http://bugs.mysql.com/bug.php?id=23701>

For python packages with C extensions, distutils, and hence setuptools, 
does know how to build fat (ppc-32, intel-32) and even universal 
({ppc|intel}{32|64}) libraries, depending on how the python distribution 
itself was built and assuming the proper OSX SDK was installed from an 
Xcode (Apple Developer Tools) distribution (see /Developer/SDKs/). The 
recent pythons (2.5/2.6) from python.org are fat and were built with the 
MacOSX10.4u.sdk.

BTW, I just use easy_install (from setuptools) to build and install 
MySQLdb and, for that matter, nearly all python packages these days.  As 
long as the package uses distutils and doesn't get too fancy with 
overriding or extending them, they install just fine with easy_install 
as an egg, even if they don't explicitly use setuptools.  In the 
increasingly rare cases where that don't work, it's usually immediately 
obvious, i.e. the install fails.

Also, eggs don't have to be installed as single zip files: that's just 
the default.   Add --always-unzip  or -Z to the easy_install options to 
install unzipped.   To always install unzipped, create a 
.pydistutils.cfg file in your home directory with an [easy_install] 
section:

[easy_install]
zip-ok = 0

So, once you have a universal mysql client library installed,

  easy_install -Z MySQL-python

should be all you need to download, build, and install mysqldb.

HTH!

Ah, I didn't know that.  Poking around in Resources/lib (and including 
unzipping site-packages.zip), I find things like mySQL.pyc, and a 
MySQLdb folder containing a bunch of other .pyc files.  Nothing else 
though; just Python bytecode.  Is it possible that MySQLdb is written 
entirely in Python, and was never the problem at all?  I.e., that given 
a suitable portable mysql client library, MySQLdb will Just Work?

But OK, now this brings up the question of why my 
libmysqlclient_r.16.dylib is Intel-only, when I took pains to install a 
UB version of MySQL (c.f. the "Installing MySQL" section of 
<http://www.dotancohen.com/howto/python-app-mac.html>).  (I'm going to 
do a fresh download of that mysql binary package and poke around inside 
to see what I find.)

But now I'm confused again.  I thought this library was part of the 
mysql distribution -- not something created by the Python script 
(indeed, not something specific to Python at all).  If that's so, why 
would "setup.py build" have anything to do with it?

Thanks for your patience,

hi all,

first: theres a library called VideoCapture for Win32 environments  
which makes it possible to access video-capture devices. is there  
something similar for macs?

second: i would like to do real-time video-processing (like bright- 
spot detection, movement detection, ...) using images recorded by a  
webcam. is python suited to do so? any references?

i appreciate your hints to this quite crude question.

best,

no -- there is C code that needs to be compiled, I"m pretty sure anyway! 
maybe I'll get a chance to try it myself.

that would be great, but no, I don't think so.

"libmysqlclient" is part of mysql. I"m pretty sure that the python 
module requires a compiled extension, that links against it, and it will 
be called something like _mysql.so, and should get put in the build 
directory when you built it, and installed somewhere in site-packages 
when you install it.

no problem -- this really is complex!

could be -- I'm just guessing here, but I suspect that libmysqlclient 
may be used only for custom clients, so it may have gotten built 
non-universal and no one has noticed. What do the other libs in there 
look like?

No, MySQLdb does have a C extension component.  There should be a 
_mysql.so there somewhere.  If you build it with easy_install, the 
unzipped egg layout is:
$ ls -l

and, with a fat python config:

Perhaps you can get away with making a symlink or copying from one to

with:

ls build/lib.macosx-10.3-ppc-2.5/
MySQLdb              _mysql.so            _mysql_exceptions.py


I've just done it straight, with a PPC build of MySQL -- I got:

gcc -arch i386 -arch ppc -isysroot /Developer/SDKs/MacOSX10.4u.sdk -g 
-bundle -undefined dynamic_lookup 
build/temp.macosx-10.3-ppc-2.5/_mysql.o -L/usr/local/mysql/lib

/usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: warning 
build/temp.macosx-10.3-ppc-2.5/_mysql.o cputype (18, architecture ppc) 
does not match cputype (7) for specified -arch flag: i386 (file not loaded)


which I think makes sense, as _mysql.o was built with the flags from 
mysql-config, which only gives PPC as it's now set on my machine.

However:

$ file build/lib.macosx-10.3-ppc-2.5/_mysql.so
build/lib.macosx-10.3-ppc-2.5/_mysql.so: Mach-O universal binary with 2 
architectures
build/lib.macosx-10.3-ppc-2.5/_mysql.so (for architecture i386): 
Mach-O bundle i386
build/lib.macosx-10.3-ppc-2.5/_mysql.so (for architecture ppc): Mach-O 
bundle ppc


so I did get a universal _mysql.so, but I doubt it would work on a Intel 
machine.

Ned, how did you built that?

Ah, out of curiosity I download the latest mysql-5.0 universal build and 
there all of the library files in lib *are* indeed universal (which can 
be verified by a doing a "file lib*"):

~/Downloads/mysql-5.0.67-osx10.4-universal/lib$ ls -l

$ diff libmysqlclient_r.15.0.0.dylib libmysqlclient_r.15.dylib
$

So, it looks like the 5.1 universal download is slightly broken and the 
copying suggestion should work.

   easy_install -Z MySQL-python

using python from the python.org 2.5 universal installer.

Yes, but see my followup post.  After comparing the 5.0 and 5.1 
tarballs, it seems clear that the libs on the 5.1 tarball are hosed a 
bit.

I've opened bug #41940 on the MySQL tracker to document the problem.

You are correct; I found _mysql.so in the 
Resources/lib/python2.5/lib-dynload folder.  It's a universal binary.

I'm going to come back to this via another post -- sounds like Ned has 
found that the 5.1 distribution of MySQL really is a bit messed up, but 
the 5.0 one is OK.  So maybe if I just do this over with the 5.0 distro, 
it will work.

Best,

Note, I haven't tested this so YMMV.  If you can get away with using a 
5.0 client, that should work.  But if you just fix-up the 5.1 libs with 
a couple of copies that should work, too.   Go to the directory of your 
mysql installation, probably something like:

cd /usr/local/mysql-5.1.30-osx10.4-universal

Then:

cd lib
ls -l *.dylib
file *.dylib

sudo sh

cp -p libmysqlclient.16.0.0.dylib libmysqlclient.16.dylib
cp -p libmysqlclient.16.0.0.dylib libmysqlclient.dylib

cp -p libmysqlclient_r.16.0.0.dylib libmysqlclient_r.16.dylib
cp -p libmysqlclient_r.16.0.0.dylib libmysqlclient_r.dylib

OK, I think I see your point here.  In the 5.1 download, 
libmysqlclient_r.16.0.0.dylib is universal, but 
libmysqlclient_r.16.dylib is not.  From the looks of the 5.0 download, 
these should be the same (both universal).

> Perhaps you can get away with making a symlink or copying from one to 
> the other??

Seems reasonable, so as a test, I copied libmysqlclient_r.16.0.0.dylib 
into my app bundle on top of libmysqlclient_r.16.dylib.  I verified with 
"file" that my libmysqlclient_r.16.dylib is now universal, and verified 
that my app still runs on an Intel Mac.  But on a PPC (10.4) Mac, it 
still fails:

   File 
"/Users/jstrout/Temp/etownCentral.app/Contents/Resources/IADB.py", line 
12, in <module>
     import MySQLdb
   File "MySQLdb/__init__.pyc", line 19, in <module>
ImportError: 
dlopen(/Users/jstrout/Temp/etownCentral.app/Contents/Resources/lib/python2.5/lib-dynload/_mysql.so, 
2): Symbol not found: _mysql_get_host_info
   Referenced from: 
/Users/jstrout/Temp/etownCentral.app/Contents/Resources/lib/python2.5/lib-dynload/_mysql.so
   Expected in: dynamic lookup

I used "otool -L" to check the dependencies of both _mysql.so and 
libmysqlclient_r.16.dylib.  All seemed satisfactory, though the one for 
the latter is a little strange:

$ otool -L libmysqlclient_r.16.dylib
libmysqlclient_r.16.dylib:
         /usr/local/mysql/lib/libmysqlclient_r.16.dylib (compatibility 
version 17.0.0, current version 17.0.0)
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, 
current version 88.1.11)

I'm not sure why libmysqlclient_r.16.dylib is listing a dependency on 
itself, but in /usr/local.  There is no /usr/local/mysql on a standard 
machine (including the one where this is failing).  Yet otool does list 
a "current version", perhaps because it's finding itself within the app 
bundle?  Seems a little odd.

The dependencies for mysql.so itself all look fine to me and refer only 
to three system files that really do exist.

So I'm stumped again... both libraries are now universal, yet for some 
reason, the _mysql_get_host_info symbol is not resolving.  Any idea what 
to try next?

Thanks,
- Joe

Did you try rebuilding the app bundle with py2app after the mysql libs 
were fixed?

otools -L on the 5.0 libs I have installed shows similar results.  I 
wouldn't worry about it.

Safer: after fixing the mysql libs installed on your mac (not in the app 
bundle), first rebuild MySQLdb, then rebuild the app with py2app.

yep -- the linking probably failed for the PPC side.

Hmm.  This doesn't appear to have worked, but it's failing in an odd way 
that I don't understand.  Here's what I did:

1. The above copying, vebatim.
2. In the MySQL-python-1.2.2 source directory:
    2a. sudo python setup.py clean
    2b. sudo python setup.py build
    2c. sudo python setup.py install
3. In my project directory:
    3a. rm -rf build/*
    3b. rm -rf dist/*
    3c. python setup.py py2app
4. Ran the resulting app on ANY machine -- even the one I just built it 
on -- and it fails with:

...File "IADB.pyc", line 12, in <module>
  ImportError: No module named MySQLdb

Note that the program still works fine when I run it on the command line 
(with "python eTownCentral.py"), and when I enter python and try "import 
MySQLdb" that works too, so I haven't broken MySQLdb completely.  It's 
just not included in my app bundle now.  Within Frameworks, I see only 
libwx_macud-2.8.0.dylib and Python.framework; no libmysqlclient at all. 
  And in lib-dynload, there is no longer a _mysqldb.so.

The weird thing is, my python source and setup.py have not changed.  So 
why is py2app suddenly failing to realize that it should include MySQLdb?

Thanks,
- Joe

hi all,

first: theres a library called VideoCapture for Win32 environments  
which makes it possible to access video-capture devices. is there  
something similar for macs?

second: i would like to do real-time video-processing (like bright- 
spot detection, movement detection, ...) using images recorded by a  
webcam. is python suited to do so? any references?

i appreciate your hints to this quite crude question.

best,

Subject: [Pythonmac-SIG] How to get setuptools to build a Universal Binary?
Message-ID: <4964F9D4.8060704@inspiringapps.com>

I'm (still) trying to make a neatly packaged Python app that works on 
both PPC and Intel Macs.  All is good except for mysqldb; following the 
procedure I've documented at 
<http://www.dotancohen.com/howto/python-app-mac.html>, my app bundle 
contains an Intel-only binary of the mysqldb library 
(libmysqlclient_r.16.dylib).

This page 
(http://developer.apple.com/opensource/buildingopensourceuniversal.html) 
at Apple suggests a possible solution: build separate Intel and PPC 
binaries, and then combine them with lipo.  But of course that's using 
Makefiles.  MySQLdb instead uses setuptools.

So: does anyone have a clue how I can convince setuptools to build a PPC 
binary (or better yet, a Universal one) on an Intel machine?

This may or may not also be involved:
   <http://bugs.python.org/setuptools/issue19>

Any advice will be greatly appreciated...

Thanks,
- Joe

Woot!  I finally got my MySQLdb-using Python app working as a Universal 
Binary!  (Trying to make sure all the relevant keywords are there for 
future googlers.)

The root cause of most of the trouble was the broken 5.1 MySQL 
distribution (bug #41940 on the MySQL tracker).  I tried patching it up 
as Ned suggested, but that didn't work for me.  However, going back to 
5.0 did work.

Here's what I did in more detail:

1. Deleted /usr/local/mysql-5.1.30-osx10.4-universal, and the 
MySQL-python egg (in 
/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/).

2. Downloaded the mysql-5.0.67-osx10.4-universal tarball from the MySQL 
5.0 downloads page.  Unpacked this into /usr/local, changed ownership 
and group as usual, and made the symlink to it as /usr/local/mysql. 
(Confirmed that all dylibs in its lib directory were really universal, 
using "file *.dylib".)

3. Reinstalled MySQLdb using the easy method Ned suggested: 
"easy_install -Z MySQL-python".  This worked fine; all the extra hackery 
at 
<http://www.mangoorange.com/2008/08/01/installing-python-mysqldb-122-on-mac-os-x/> 
appears to be unnecessary when you use easy_install, as is the manual 
unzipping of the egg (provided you remember the -Z flag).  Navigated 
into the newly created egg in site-packages and verified that the 
_mysql.so file was universal.

4. Rebuilt my app with py2app.

The resulting app works in 10.4 and 10.5 on both PPC and Intel machines. 
  Hooray!

Now, let's see... I owe a beer (or other beverage of choice) to Ned, 
Chris, Robin, and Andy... and I'm off to make a donation to both 
wxPython and MySQLdb...

Many thanks,
- Joe

Out of curiosity, what does the mysql_config command give you now?  
i.e. the output of:

$ mysql_config --cflags

Still no "arch" flags:

NOTE: I'm sending this all here, so it will be here for the archives


This is about trying to build a Universal MySqlDb module for the 
python.org Universal python (2.5.2 in this case). The issue is that you 
need to start with Universal MySQL libs. MySQL does indeed distribute 
Universal libs (ppc, ppc64, and i386 -- apparently not i386-64), but 
only as a tarball, not as as in installer in a .dmg.

However, there appears to be a bug in the tarball for version 5.1.30, 
and this note is about that:


I've got my curiosity up, so I've poked into this a bit more:

looking in:

/usr/local/mysql-5.1.30-osx10.4-universal/lib

things are clearly broken for example, we have:

15266468 Nov 20 23:32 libmysqlclient.16.0.0.dylib
4781040 Nov 15 14:57 libmysqlclient.16.dylib

The 16.0.0 version is Universal (ppc, ppc64, and i386), and the 16.dylib 
one is only i386 (and this in on a ppc machine!) different date, too...

But it's not just that. If I look in the ppc build I got from MySQL:

/usr/local/mysql-5.1.30-osx10.4-powerpc/lib

Nov 15 15:29 libmysqlclient.16.0.0.dylib
27 Jan  7 13:13 libmysqlclient.16.dylib -> libmysqlclient.16.0.0.dylib

so the 16.dylib version is supposed to be a symlink to the 16.0.0.dylib 
version, which is the usual *nix practice. Indeed, there are no symlinks 
in the lib dir at all.


So I think the way proper way to fix it is not to copy, but rather to 
fix the symlinks. Here's a script to do it (it needs to be run from the 
lib dir):

#!/bin/sh

# script to fix mysql lib dir in Universal dist

ln -s -f libmysqlclient.16.0.0.dylib libmysqlclient.16.dylib
ln -s -f libmysqlclient.16.0.0.dylib libmysqlclient.dylib

ln -s -f libmysqlclient_r.16.0.0.dylib libmysqlclient_r.16.dylib
ln -s -f libmysqlclient_r.16.0.0.dylib libmysqlclient_r.dylib

(also enclosed as a file)

Now to test the build of the python extension (MySQL-python-1.2.2)

first remove any old build and dist dirs (distutils is not so good at 
cleaning up):

$ rm -rf build dist

now try the build:

$ python setup.py build

no errors, and I see: "-arch ppc -arch i386" in the gcc line, so it 
looks like it's getting a universal build. Poking into:

build/lib.macosx-10.3-ppc-2.5 (distutils isn't really smart about 
Universal, so it creates this dir named for the host system)

I get:
file _mysql.so
_mysql.so: Mach-O universal binary with 2 architectures
_mysql.so (for architecture i386):      Mach-O bundle i386
_mysql.so (for architecture ppc):       Mach-O bundle ppc


which looks good. and:

$ otool -L _mysql.so _mysql.so:
         /usr/local/mysql/lib/libmysqlclient_r.16.dylib (compatibility 
version 17.0.0, current version 17.0.0)
         /usr/lib/libz.1.dylib (compatibility version 1.0.0, current 
version 1.2.3)
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, 
current version 88.3.9)
         /usr/lib/libmx.A.dylib (compatibility version 1.0.0, current 
version 47.1.0)

and just to make sure:

$ file /usr/local/mysql/lib/libmysqlclient_r.16.dylib
/usr/local/mysql/lib/libmysqlclient_r.16.dylib: symbolic link to 
`libmysqlclient_r.16.0.0.dylib'

that's the link I created. And:

$ file /usr/local/mysql/lib/libmysqlclient_r.16.0.0.dylib

/usr/local/mysql/lib/libmysqlclient_r.16.0.0.dylib: Mach-O universal 
binary with 3 architectures

/usr/local/mysql/lib/libmysqlclient_r.16.0.0.dylib (for architecture 
i386):     Mach-O dynamically linked shared library i386
/usr/local/mysql/lib/libmysqlclient_r.16.0.0.dylib (for architecture 
ppc64):    Mach-O 64-bit dynamically linked shared library ppc64
/usr/local/mysql/lib/libmysqlclient_r.16.0.0.dylib (for architecture 
ppc):      Mach-O dynamically linked shared library ppc

Which is what we want.

$ python setup.py install

note: I have setuptools set to never install zip packages, 'cause they 
don't work right with py2app, and I like being able to see what's in 
them, etc. You can do this by creating a .pydistutils.cfg  file in your 
home dir, and putting:

[easy_install]
zip-ok = 0

in it.

now to test:

$ python
Python 2.5.2 (r252:60911, Feb 22 2008, 07:57:53)
[GCC 4.0.1 (Apple Computer, Inc. build 5363)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
 >>> import _mysql
 >>>

At least it imports -- I don't have anything real to test with!

Further note:

It would be nice to distribute a binary of the python package. However, 
it would depend in that mysql dylib. I think the right way to do it 
would be to link the python extension against the static lib instead. To 
do that, I'm going to (temporarily) remove all the dylibs from the mysql 
lib dir, so it can only link to the static lib.

(in the mysql libs dir)

$ mkdir temp
$ mv *.dylib temp/

now build the python lib again:

$ rm -rf build dist

$ python setup.py build

which ran without errors.

check the lib:

$ otool -L _mysql.so
_mysql.so:
         /usr/lib/libz.1.dylib (compatibility version 1.0.0, current 
version 1.2.3)
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, 
current version 88.3.9)
         /usr/lib/libmx.A.dylib (compatibility version 1.0.0, current 
version 47.1.0)


whoo hoo! it's not longer dependent on the mysql dylib!

$ python setup.py install

and I've got it installed and it seems to work, but still needs testing.

I've now got a binary egg file -- anyone want to test it? It's about 
3MB, which I think is too big to post here, but I'll send it to anyone 
that asks.

Also, we really need a place to post it, if it works!

I recommend actually deleting the build and dist directories -- 
distutils in not all that good at cleaning up.

>  ImportError: No module named MySQLdb

that is odd.


 > why is py2app suddenly failing to realize that it should include MySQLdb?

One guess -- I think "setup.py install" puts a zipped egg in by default, 
and py2app does not work well with zipped eggs. I couldn't figure out 
how to tell it not to do that (with easy install, you pass the -Z 
option). However, I set a preferences file so that it would never put in 
zipped eggs:

by creating a .pydistutils.cfg  file in your home dir, and putting:

[easy_install]
zip-ok = 0

in it. (I found that on the web somewhere...)


Take a look at the other note I jsut posted -- I have successfully build 
a Universal version that is statically linked to the mysql lib -- though 
I don't know if it works beyond importing-- can you test for me?

-Chris

PS: I think you may owe me two beers now ;-)

Ned, thanks for posting this bug.

Note that easy_install runs the same old "setup.py build" that you do by 
hand - so the bugs that that post corrects are probably fixed in the source.


By the way, I've build a binary universal egg that should be 
re-distributable - please let me know if you want to test it, or have a 
place to host it.

Has anyone installed PythonMagick on Mac OS X?

I have ImageMagick and Python both installed and working on my Mac,  
so a way to make them work together seems like a great idea.

I found it and downloaded it in source code form. Source code is  
fine, but there is a list of requirements for other bits of software  
that I have never heard of, so I would like to know if this is going  
to work before I start chasing all this stuff down.

Thanks in anticipation,

Putting it out on the web isn't worth, IMHO.  I fear it would turn into 
YAPackage that doesn't get updated and eventually causes more trouble 
than it's worth.  Looking back over Joe's experience, my take it that 
the root cause of nearly all of the difficulties was the faulty MySQL 
5.1.30 distribution, which of course he had no reason to assume was bad.  
If he had been lucky enough to start with the 5.0 dist he ended up with 
and followed the standard install of MySQLdb, the MySQL part of his app 
building would have been straightforward.

I think documenting the problem with 5.1.30, which we've done in the 
pythonmac world and on the MySQL tracker, and if necessary "encouraging" 
a resolution over at MySQL are sufficient actions for now.

In any case, just my $0.02.

Hi Michael,

I see some faint traces on Google of something called "PySight" that  
can grab images from iSight cameras. There may be some Apple-provided  
frameworks for grabbing iSight images as well, which could be called  
via PyObjC. Failing that, I'm sure you can find some C-level webcam  
drivers for OS X. Writing python wrappers for these (using either  
Cython [an update to pyrex] or even just the Python API) shouldn't be  
a big trouble at all if you've any C experience. (I could provide some  
help/advice along these lines if you need.)

My suggestion is to learn a bit about numpy, the python numerical  
computing module, and it's friend scipy, which provides more domain- 
specific routines. Specifically, passing a chunk of memory  
(representing an image as an array of bytes) from a C library to numpy  
is extremely easy, using the C API or even Cython. And scipy provides  
good image-manipulation tools in its ndimage and signal sub-modules.  
These are all in C and fortran, so real-time should be achievable. The  
numpy and scipy lists have really good folks on them who know their  
stuff (including some imaging people), so if you have specific  
questions about image processing with those tools, definitely ask there.

Alternately, there are python wrappers for OpenCV, which provides a  
TON of basic to advanced imaging stuff. It can be a bit overwhelming,  
but it's good and optimized for speed. (OpenCV has webcam drivers, but  
I don't think they work on OS X.) IMO, the ctypes-based wrappers are  
likely better and easier to use/extend than the SWIG ones.

Visualization might be tricky, though...  you'll likely (?) want some  
way to blit the images to the screen at some point, and so you'll want  
to choose a GUI toolkit. You could use Cocoa with PyObjC, or tkinter,  
or wx, or whatever. Most of these can accept a blob of memory and draw  
it on screen as a image. I use Pyglet, which is a nice, thin, cross- 
platform wrapper for simple windowing and OpenGL. (No widget toolkit  
for pyglet, but I just use it to throw pixels onto a 2D surface as  
fast as possible.) As a bonus, I've written some code that allows you  
to run a pyglet window in the background, which can be controlled from  
the python interpreter. (Most windowing toolkits need their own main()  
routine to run, which precludes interactive control via a python  
shell, unless you embed that in the main(). Ipython has tools to do  
this for wx and tkinter, but it's a bit klugey, IMO.) Ask me if you  
want this code.

Message-ID: <49668C6E.8030406@noaa.gov>

Hi folks,

I've built what I think should be a binary egg for mySQLdb. It should 
work for the python.org Universal build of python2.5, on OS-X 10.3.9 and 
above.

However, it hasn't really been tested.

I haven't enclosed it here, as it's about 3MB, but if you drop me a 
note, I'll send it to you to test.

Once it's been tested, the MySQLdb folks have offered to put it up on 
their sourceforge download page, which would be nice.

Subject: [Pythonmac-SIG] Warning: The process has forked and you cannot use
	this CoreFoundation functionality safely.
Message-ID: <rowen-5CB5C1.11190909012009@news.gmane.org>

I maintain a RO.DS9, a cross-platform Python module that controls ds9 
(a.k.a. SAOImage DS9), an astronomical image viewer.

The module starts by launching ds9 with a window of a known name (this 
is required to further command it), and that's where I run into trouble 
on MacOS X.

On unix and Windows ds9 is an executable that I run using 
subprocess.Open and provide the necessary command-line arguments to set 
the window name. That works fine.

On MacOS X I used to do the same thing. The application is a bundle 
"SAOImage DS9.app" that contains the executable ds9 that takes the same 
command-line arguments. Running ds9 still works on Leopard, but results 
in the nasty warning:

The process has forked and you cannot use this CoreFoundation 
functionality safely. You MUST exec().

>From a google search, I found this:
-------
This is caused by programs that use the fork() or daemon() function in 
combination with higher-level APIs. In Leopard you cannot use the 
CoreFoundation (CF...) APIs on the child side of a fork() without 
following it with an exec*() function. This has always been true, but 
Leopard is much more stingy about this kind of thing.

So clearly I should not be doing this. But what to do instead?

The simplest, but inadequate, alternative is to use subprocess to run 
the command "open -a SAOImage DS9". This works but I can't send 
command-line arguments, so I can't control the name of the window, which 
cripples the module.

Is there some Mac-safe way to start the ds9 command-line application 
from my python module? I don't really know what it means to "run an 
exec*() function after a fork" and didn't think I was forking anything 
anyway -- I'm trying to start an independent process. I fear that the 
fork may be in ds9 itself and that there's nothing I can do, but I hope 
I'm wrong.

python version please and where might I find this code?
fork(3) is the unix system call that copies the program and one becomes a
child process and another a parent (which is supposed to wait on the child).
The child process normally calls a function from the exec(2) family soon
afterward. Leopard is probably being anal because until exec, that is 2
programms with the same amount of address size and Core Foundation may not
be able to handel that. The error

uses the word 'this', which implies it gave you the CoreFoundation API call
that triggered the warning.

It is evident that the program is handeling something in a Mac OS Classic
way that should be handled in a BSD way. That could be either Python's fault
or the progammer.

hi zach,

thanks a lot for your help. so far i made first steps using PySight  
which works fine with my iSight camera.

i'm able to aquire images and to process them, using code-snippets  
from here and there, but i lack an idea of PyObjC and i am still a bit  
overwhelmed by it. i would prefer to do as little as possible with it,  
just acquiring data.

scipy/numpy (together with ipython) are what i use for data analysis  
in general and i'm going to work with them for pattern detection,  
though up to now i lack a systematic approach to pass them 'a chunk of  
memory' .

for visualisation i find pyglet very interesting. i'd be happy if you  
could send me your code that allows to run a pyglet window in the  
background.

best,
michael

Cool, I'm glad this worked. I'll have to try PySight out.

If you can get from C code a python object exporting the "buffer  
protocol" (maybe a string representing image bytes, or whatever), it's  
pretty easy to construct a numpy array, from a variety of functions  
(like numpy.frombuffer/fromstring, or just using the numpy.ndarray  
constructor). Alternately, and this I find to be the easiest way of  
dealing with C-level stuff, I construct the array first using  
numpy.ones/zeros/empty, and then grab a pointer to the memory from  
that array, and pass that into the C function to fill in, or process,  
or whatever. This is pretty easy with ctypes:

I'll send that off-list. Anyone should feel free to contact me for

I had the exact same problem and fixed it adding that line to the __boot__.py
file in the app's package contents, but I was wondering if there was a way
to tell py2app to do this automatically in the setup script because
otherwise I'd have to do it manually every time I build my project. Py2exe
has a custom boot script option but it doesn't look like py2app does.

Thanks,

clearly a bad idea!

I haven't seen that option -- but you're right it should. Some quick 
poking did not make it clear to me where py2app builds the __boot.__py 
file though.

Anyway, you can always hack around this by adding some code to your 
setup.py that changes __boot__.py after building the app.

I find I have to add a lot of extra fiddling code to accommodate eggs 
and other deficiencies in py2app, but I don't have the time to get to 
know py2app enough to submit a patch, so there you go.

I've been trying to figure out where the _real_ current Py2app is.

Here's one source of confusion:

	The __init__.py in the py2app directory as distributed by Apple with  
Leopard contains:
		__version__ = "0.4.1"

	The __init__.py file, from the trunk of the repository at: http://svn.red-bean.com/bob/py2app/trunk/
		__version__ = "0.3"

	The __init__.py file from the trunk of the repository at : http://svn.pythonmac.org/py2app/py2app/trunk
		__version__ = "0.4.2"

	The __init__.py file from the trunk at :

	The python.org file references two different py2app distributions  
on : http://wiki.python.org/moin/MacPython/py2app
	
	The one at http://undefined.org/python/py2app.html refers back to the http://svn.red-bean.com/bob/py2app/trunk/ 
  so at least that's not a new version (though it is another new place  
for the documentation).
	
Can anyone tell me which of these is the actual development repository?

Sorry if this has been answered before but I could not find a  
definitive answer in the archives.

I really need to add some things (compiling xib -> nib, for example)  
to build my project and I'd prefer to start with something to which I  
could actually contribute my changes.

Thanks,

Subject: [Pythonmac-SIG] Warning: The process has forked and you cannot
	use this CoreFoundation functionality safely.
References: <rowen-5CB5C1.11190909012009@news.gmane.org>

Message-ID: <rowen-E828DA.13513014012009@news.gmane.org>

A good question, and in the process of answering it I found that problem 
is caused by running a "Tiger" version of SAOImage DS9 on "Leopard". 
These can be downloaded from:
<http://hea-www.harvard.edu/RD/ds9/>

Python version is 2.5.2 (the version from python.org).
I'm no an Intel Mac running 10.5.6.
This trivial test case shows the problem:

import subprocess
args = ('/Applications/SAOImage DS9.app/Contents/MacOS/ds9', '-title', 
'foo', '-port', '0')
subprocess.Popen(args=args)

This works correctly on Leopard if running a Leopard version of the DS9. 
But if I use a Tiger version of DS9 then after the Popen "call" returns 
I see a host of these warning messages:

The process has forked and you cannot use this CoreFoundation 
functionality safely. You MUST exec().
Break on 
__THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONA
LITY___YOU_MUST_EXEC__() to debug.

(I have verified this with DS9 5.4 -- Leopard and Tiger versions -- but 
I first found it out because I had an older Tiger DS9 that I had not 
upgraded when I switched to Leopard).

-- Russell

P.S. As a result of this test I am skeptical of the Tiger version of 
DS9, because the message warns of something that should not have been 
done in either MacOS X 10.4 or 10.5 -- even though only 10.5 warns about 
it.

Using Python 2.6.1 although I get the error when reverting to 2.5.4 as
well. This is only on my MacPro at work. My MacBook Pro at home does not
produce the error.

Thanks,

Subject: [Pythonmac-SIG] socket code works on Win32 but not Mac :-(
Message-ID: <496F0FAC.30804@cemery.org.uk>

Dear All,

I'm writing a Python FOSS application and am *very* keen to keep it
platform agnostic.

I don't own a Mac, but have access to some sympathetic Mac owners. :-)

The following code works just fine under Windows XP and Vista but not on
MacOS X (currently no idea what version, though Python is 2.5.?). Any
thoughts?

def get_my_ip_address():
    ret=None
    try:
        s=socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
        s.connect(('google.com', 0))
        sn=s.getsockname()
        if sn:
            ret=sn[0]
    except socket.error, e:
        hn=socket.gethostname()
        ret=socket.gethostbyname(hn)
    return ret

produces the stack:

Traceback (most recent call last):
  File "./sarnie_client.py", line 181, in get_my_ip_address
    s.connect(('google.com', 0))
  File "<string>", line 1, in connect
socket.error: (49, "Can't assign requested address")

My application has been given firewall rights accept connections from
the Internet. Is there perhaps anything else that I should configure?

TIA

If you create an app with py2app then right click on it and click show
package contents then you can browse the app's contents. __boot__.py is
located in Content/resources/__boot__.py.

Yeah, I tried adding my custom __boot__.py to the data files since they were
being stored in the same location but py2app still used it's own creation.
Any ideas as to how I could change the file after it's been made? I'm new to
py2app so just a point in the right direction would be very helpful.

yes, I meant I have no idea where in the Py2app code, py2app actually 
generates the __boot__.py file, so I can't see where to add a patch...

as you've seen, an app bundle is simply a directory with a special name 
and structure -- Finder shows it in a special way, but you can 
manipulate the files in it from the command line or a python script just 
like you'd manipulate any files.

so, in your setup.py, after running setup(), you can add code that 
either adds stuff to __boot__.py, or replaces it with another one -- 
whatever is easiest.

What does this even mean?  "google.com" is a domain, not a server
(though it does forward to "www.google.com").  And port 0?  Does
anything listen on port 0?  Sounds like OS X is the only platform that
gets this right :-).  Try this:

  s.connect(('www.google.com', 80))

for instance, to connect to the Web server.

Don't use port 0.

Thanks for all the help.
It's clear the port was the issue.

Hi there,

dumb question, probably, but:

can I build a MacOS App, using py2app, under Windows?

If not, is there any way I can build a MacOS Python Application using a
Windows PC?

If there's no way, how do I find a Mac / Python developer to help me
distribute my application for the Mac?

Not legally, but there are VMWare images to run OSX in VMWare on
Windows or you can make a 'hackintosh'.
For both solutions do a google search.

You could ask here for instance.
Is your application open source or a commercial app?

In summary, it's a bit like a PA system for an office receptionist to
announce things like "The sandwich van is outside".
It's Python, Pyro and wxPython and some as-yet-unreleased wxPython
extras called AGW.

The file is generated by code in the module py2app.build_app, from fragments in py2app.bootstrap.

Subject: [Pythonmac-SIG] Pygame 1.8.1 broke py2app 0.4.2
Message-ID: <1itokfx.sf5xrbj6072N%pdorange@mac.com>

I finally got around the bug i got with py2app.

Config : MaxOS X 10.5 / Python 2.5 / Pygame 1.8.1 / py2App 0.4.2

I recently update my Mac from 10.4 to 10.5.
I also of course reinstall all required modules.

After this the bundle app i made with py2app (for my small pygame games)
cause the bundled app to quit at start...

I made several experience but nothing works.

First i thought that perhaps that's because i used the default python
installed with MacOS X, i reinstall a new one as user, not work.

I try several versions of py2app, not working.

Finally i realized that with my previous config i was using pygame
1.8.0rc5 and now 1.8.1 (2) (because 1.8.1 was released).
So i try to downgrade, as i can't find the archive, i download the
source code for 1.8.0 (3) build and install...

And now it works fine, the bundled app (with py2app 0.4.2) works fine...
I just have to manually install libjpeg and libpng (thanks to (1))

So it seems that pygame 1.8.1 broke py2app at some point, or perhaps
that the 1.8.1 package for mac if not compiled with the appropriate
config...

(1) http://ethan.tira-thompson.com/Mac%20OS%20X%20Ports.html
(2) 1.8.1 Mac : pygame-1.8.1release-py2.5-macosx10.5.mpkg
(3) 1.8.0 i compile : pygame-1.8.0release

Thanks Ronald. I've No time now, but perhaps it could be patched to load 
a user-supplied boot file -- py2exe has this option, and it's quite handy.

Thank you, that solved my problem. I went into the bootstrap folder and
added the line into build_app.py, now it's always included in my apps

Is there a way to rebuild pyobjc on Leopard using the XCode 3.1/gcc  
4.01 tools?

I have tried pulling the trunk and tagged r200-leopard builds of  
pyobjc from http://svn.red-bean.com/pyobjc and neither will build  
using the 02-develop-all.sh build file.

There are lots of C compiler errors starting with:

libffi-src/powerpc/ppc-ffi_darwin.c:41:67: error: libkern/

Then there's:

Way too many errors and what gets 'installed' doesn't link against an  
app at all.

Seems also to have trashed the one that was there, not sure there's a  
way to repair it short of a reinstall (DevTools or OS X install?).

Is there a checkout I'm missing or a trick to building pyobjc on  
Leopard from source?

Thanks,

S

Hi all,

Would someone please confirm or deny that as from OS 10.5.6 it is no

I'm pretty sure is was still possible under 10.5.x (for x<6)

Subject: [Pythonmac-SIG] [pythonmac-sig] Py2app and Driver not loaded error
 from PyQt4+sqlite
Message-ID: <21610538.post@talk.nabble.com>


I'm trying to convert python code into a mac application with py2app.
My python code uses PyQt4 to access a sqlite db.
At run time (on a different mac from the one where I build the .app where
there is no PyQt4+Qt4 installed) I get the error:
Driver not loaded
Unable to establish a database connection
This example needs SQLite support
...
On Windows, using py2exe, I had the same problem and I solved it 
coping:
           ...\Qt\version\plugins\sqldrivers\*.*
to:
           ...\myApp\sqldrivers\*

On Mac  I tried coping libqsqlite.dylib into:
            .../myApp/Contents/Frameworks/QtSql.framework/ 
and into:
            .../myApp/Contents/Frameworks/
but nothing changed.

I tried with either these options:
          options = {'py2app': {
                                "packages": ["encodings"],
                                "includes":["sip", 'PyQt4.QtSvg'],
                                'excludes': ["Tkconstants","Tkinter","tcl"]
                               }                    },
or
          options = {'py2app': {
                                "packages": ["encodings"],
                                "includes":["sip", 'PyQt4.QtSvg',
'PyQt4.QtSql'],
                                'excludes': ["Tkconstants","Tkinter","tcl"]
                               }                    },
or
          options = {'py2app': {
                                "packages": ["encodings"],
                                "includes":["sip", "PyQt4", 'PyQt4.QtSvg',

                                'excludes': ["Tkconstants","Tkinter","tcl"]
                               }                    },
but nothing changed.

I tried also:
         options = {'py2app': {
                                "packages": ["encodings"],
                               "includes":["sip",

                                'excludes': ["Tkconstants","Tkinter","tcl"]
                              }                    },
but in this case I get this error:

I'm not sure if you need to get a specific page number or the count of
pages for the document. If you need the total page count (for whatever
reason) from a PDF document, you can use the Quartz 2D bindings as so:

<http://bit.ly/jV7P>

I don't know if Quartz 2D will give you the rest of what you want, but
perhaps PyObjC will. (I've got less experience with PyObjC than the
Quartz 2D bindings, and not much experience with the Quartz 2D bindings.
<grin>)

Of course, either of these ways would not be pure Python and would
require at least Mac OS X 10.3 (Quartz 2D) or 10.5 (for bundled PyObjC).

How to manage a module with several versions on MacOS X ?

My modules are installed in :
"/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-pa
ckages/"

But for some modules i need several version (stable 1.8.1 and test 1.9.0
for example : for pygame here).

I've installed the stableone from source and i go into a
"pygame-1.8.0release-py2.5-macosx-10.3-i386.egg" directory.

I just install the 1.9 (for test) and it go into "pygame" directory

So now  i got 2 versions of pygame in the site-packages dir...

When i import "pygame" from python, the 1.8.0 is imported only and 1.9.0
is complely ignored... How do python choose from several package ? Do
package register them elsewhere ?
I don't know how to test (temporaly) the 1.9, but alsobe able to go back
easily to 18.8 after ?

Any clue ?

Hi, Paul.

I use a patched version of xpdf to get this stuff, which works pretty
well.  Extracts the text and wordbox info (page, word rectangle, font,
bold/italic, etc.)  for each word in the PDF.  You can download the
patch to xpdf from
http://downloads.sourceforge.net/doceng-toolkit/doceng-package-sources.zip.
You'll have to unpack the zip file and look for it in there, then apply
it to the xpdf sources and build xpdf.  I've sent the patch to the xpdf
maintainer, but haven't heard more about it from him.  See the (patched)
xpdf man page for details of the output format (ASCII text, one word
record per line).

This is also included in the UpLib release at http://uplib.parc.com/;
you'll have to register an account on the blog in order to get the
download link for that.  If you download and install one of the binary
builds of UpLib, the patched xpdf is included.

It's a while since I did any text to PDF extraction.
Last time I did, I used some tools that are part of

http://www.hforge.org/itools

Which, I seem to remember, also does elementary decryption.

Unfortunately, the Python core developers have never seen the need to do 
this -- I still don't know why.

A number of packages have developed their own systems (wx.version, for 
wxPython, for instance) -- you might see if pygame has one.

setuptools supposedly can do this for you too, if things are installed 
as eggs -- I think pkg_resources.require() is what you need -- take a 
look at the setuptools docs.

> I just install the 1.9 (for test) and it go into "pygame" directory

Ahh -so it's not an egg? If you want setuptools to help you out, you'll 
have to install the dev version as an egg, too.

no --- python looks in sys.path, and uses the first one it finds.

So, the way folks have done this in the past, pre-setuptools is 
manipulate sys,path in various ways -- a script that moves *.pth files 
around, or python code that directly manipulates sys.path (that's what 
wx.version does)

easy_install creates a easy-install.pth file that adds the paths to eggs 
that it has installed -- it puts everything before site-packages, which 
is probably why your python is finding the 1.8 egg.

I know I haven't really given you the answer, but hopefully some hints 
to so you can figure out your options.

-Chris

Subject: [Pythonmac-SIG] Error with modulegraph when using python script
 without knowed python extensions
Message-ID: <497F3E08.5010008@wallix.com>

Hi all.

I've got a python module who looks like this :

MY_PYTHON_MODULE:
  |_ setup.py
  |_ PYTHON_SOURCE/
      |_lots_of.py
  |_ PYTHON_SCRIPTS/
      |_MyScript


with setuptools a "python setup.py install" install the PYTHON_SOURCE in 
site-package of my python installation, and PYTHON_SCRIPTS are installed 
in the "install_prefix/bin".

So MyScript is already in the path, and is saw, by the user, as a 
"binary". There's a lots of python programs installed like this (like 
"spe", the python editor) on Linux.

I want now to have a Mac Port of my program. So i try py2app!

My application is, indeed, "MyScript"

But, when i run "python setup.py py2app", i have the following error 
from the find_modules.py of modulegraph tool:

line 86, in parse_mf_results
>>     raise TypeError("Don't know how to handle '%s'" % repr(src))


After a look in find_modules.py, i see that a PY_SUFFIXES list is used 
to determine which is python code and wich is not... And unfortunately, 
with a python script with no extension, it raise the previous error.

I think that, for files without extension, a detection based on 
mimetypes will be helpfull...

so, in find_modules.py, by adding


type, encoding =mimetypes.guess_type(__MY_FILE__)
if encoding == 'text/x-python':
    py_files.append(item)

will fix this problem. What did you think about that?

I have contacted the developer of modulegraph before.. but it seems that 
the support of this module is provide by people on this mailing list.



Regards,

Olivier.

You'll probably need to get something like gnuplot.py:
http://gnuplot-py.sourceforge.net/
There's a demo file inside of the package that will show you how to get started.

You might need to use something like, too:

        import Gnuplot
        Gnuplot.GnuplotOpts.gnuplot_command =
'/Applications/Gnuplot.app/Contents/Resources/bin/gnuplot'

If you're interested in using gnuplot on it's own, I maintain an open
source bundle for TextMate which you might find useful:
http://github.com/mattfoster/gnuplot-tmbundle/tree/master

I hope this helps,

Matt

I might also point out that matplotlib is available for OS X, with a  
convenient universal installer, and IMHO produces much nicer plots  
than Gnuplot (and has amazing documentation). If you haven't tried it  
out and are not particularly married to Gnuplot, I strongly recommend  
it:

You might make sure your easy_install and macholib are up to date:

each_install-U macholib==dev

If that fails and tells you to do a selfupdate then do that and try 
again.

I believe the matplotlib installer is intended for use with python.org's 
python -- not a bad thing, but it means you'll also want to install a 
new Python before you install matplotlib.

Subject: [Pythonmac-SIG] Python CoreGraphics script running in Applescript
Message-ID: <C5A8BE29.30926%jskibbie@schawk.com>

I have a script that needs to get the height and width dimensions of the
media box of a PDF using Applescript. In OS X 10.4, I was using the
following:

> set shellScript to "python " & quoted form of PythonPath & " " & POSIXThisFile
> set dims to every paragraph of (do shell script shellScript)


The PythonPath is a path to the below Python script and the POSIXThisFile is
the path to the PDF.

The response is two paragraphs where paragraph 1 is the width and paragraph
2 is the height.


Here?s the python script:

# step 1: import the required modules
import os, sys
from CoreGraphics import *

if len( sys.argv ) != 2:
    print "ERROR: useage: python example2.py pdf_filename"
    sys.exit(1)

# step 2: read the pdf file name from the command line arguments
pdf_filename = sys.argv[1]
pdf_name, ext = os.path.splitext( pdf_filename )

# step 3: create the input PDF document
provider = CGDataProviderCreateWithFilename( pdf_filename )
pdf = CGPDFDocumentCreateWithProvider( provider )
if pdf is None:
    print "ERROR reading PDF document - \r\n check that the supplied
filename points to a PDF file"
    sys.exit(1)

page_number = 1

page_width = int(page_rect.getWidth())

print "%d \r\n%d" % (page_width, page_height)


Under OS 10.5, this script now uses a deprecated function of CoreGraphics
and I get an error that says:

Can anyone steer me in the right direction on how to work with the
CGPDFPageGetBoxRect function?

Thanks.

Looks like you've installed an i386-only build of libPng in /usr/local/ 
bin, overriding the 4-way fat version included in OS X. Appscript  
builds as 32-bit fat by default, so when the linker tries to link in  
the PPC versions all the Carbon libraries it can't find the fat  
version of libPng that Carbon normally expects. The best solution  
would be to rebuild your custom libPng installation as 4-way fat,  
otherwise you'll run into the same problem when building other fat  
projects.

Subject: [Pythonmac-SIG] appscript rocket-in-dock preventing logout
Message-ID: <45862.1233357612@parc.com>

We discussed this a bit last year, but with no resolution that I
remember.  I've got a situation where a Python program is preventing
logout/shutdown.  It's a script that just runs in an endless loop
watching what app I'm working with; when it sees one it knows (Preview,
MS Word, Safari, etc.) it uses appscript to ask the app what document
I'm looking at.  It then squirrels that document away in a journal so
that I've got a record of what I've been working with.

The basic control loop is something like this:

   while True:
      ... see what's running, and possibly what document ...
      time.sleep(1.0)

When I fire this up, it creates a Python rocket icon in the dock.  Not
great, but I can live with it.  But it also prevents logout and shutdown
from working -- I keep getting the message "Logout has timed out because
the application Python has failed to quit".

Does anyone know what I've got to do to this script to keep it from
preventing logout?  For bonus points, what do I have to do to keep it
from putting the rocket in the dock?

Message-ID: <869098B6-CBC5-4D30-9C6F-22B5A1B6635B@deniau.org>

Hello,

I've noticed that the newest release of macholib (1.1) came out in  
July 2006.

Since then fixes have been made on the trunk to fix serious bugs such  
as the "unknown load command 27" problem.

(see http://mail.python.org/pipermail/pythonmac-sig/2007-June/019060.html 
  )

This problem has become quite blocking now : with Leopard, even /bin/ 
ls has the "unknown load command 27" bug.

Would it be possible to tag a new release of macholib in order to let  
port systems such as MacPorts integrate it within their distribution ?

Thanks :-)

See:

http://mail.python.org/pipermail/pythonmac-sig/2008-December/020792.html

Two options described there: replace your 'while True' loop with a  
Carbon/Cocoa event loop, allowing a GUI-based process to handle  
incoming events, or prevent the OS from automatically upgrading your  
python process to a GUI process (which it only does if it knows the  
executable is located in an application bundle, e.g. Python.app/ 
Contents/MacOS/python).

Thanks!

I'm not running Python.app -- I'm running /usr/bin/python, which if I
follow the symlinks leads me to
/System/Library/Frameworks/Python.framework/Versions/2.5/bin/python2.5,
which in turn "file" shows to be a dual-architecture executable, which
in my case is "Mach-O executable i386".  So I don't see how this rule
about automatic upgrading really applies -- I'm not using Python.app.

Perhaps it's not the OS "upgrading" the process, but rather some code in
some extension calling "TransformProcessType"
(http://www.cocoadev.com/index.pl?TransformProcessType)?

And I still don't see how to fix the logout/shutdown problem.  The Apple
Cocoa document on this,
http://developer.apple.com/documentation/Cocoa/Conceptual/AppArchitecture/Tasks/GracefulAppTermination.html,
seems to say "In Cocoa, all raw events requiring application termination
result in the invocation of the NSApplication delegation method
applicationShouldTerminate:. If the delegate does not implement this
method, the application is terminated regardless of any unsaved
documents."  Presumably, my script doesn't implement this method, and
thus "the application is terminated".  How?  Is it as simple as
installing a SIGTERM handler?

Hmmm, but when I do a "ps", I see that the system, at least, thinks I'm
using Python.app.

Actually, you probably are.  This can be a bit confusing unless you 
carefully trace through the steps in the Mac/Makefile.in, as I have been 
doing recently.

Note that the binary at <FW>/bin/python2.5 is *not* the actual python 
interpreter binary.  Rather it is the so-called pythonw binary whose 
only function is to execv to the real python binary which is located at

<FW>/Resources/Python.app/Contents/MacOS/Python

and that is inside an app bundle.

That's just a stub that kicks off the real executable at:

/System/Library/Frameworks/Python.framework/Versions/2.5/Resources/ 
Python.app/Contents/MacOS/Python

It's the Carbon Process Manager. (There's no good reason for it to do  
so, but hey, I didn't write the thing.)

Right now this is irrelevant as your process doesn't have an event loop.

Thanks, Ned.  Yes, so I see, looking at the sources.  The next question
is, since the rocket-in-the-dock only happens sometime, is there
something I can do to forestall the "promotion"?  And, is the promotion
happening because of the OS, or because of code in some extension
(appscript, say, or PyObjC).
