Subject: [C++-sig] Building tutorial example out of the boost tree,
	on Windows
Message-ID: <1372477591.1555377.1380910349772.JavaMail.root@genarts.com>

Hi folks -- new to Boost.Python, old-school C/C++/Python developer.

I'm trying to set up Boost.Python 1.54.0 on Windows 7, python 2.7.3, Visual Studio 2010. I installed boost_1_54_0 using the VS10 installer, then built bjam using 'bootstrap; .\b2 toolset=msvc', then copied bjam into my $PATH.  I can build and run the quickstart and tutorial examples in the distribution (I had to add some MSVC lib dirs as library-path requirements in Jamroot, but that's OK). But when I copy the tutorial example to a different dir, not inside the boost distribution dir, to make it more like a real project, bjam gives build errors. I changed the use-project boost location in Jamroot to /local/boost_1_54_0/ which is where boost wanted to install itself, and added a simple one-line boost-build.jam (based on something I found online):

  boost-build C:/local/boost_1_54_0/tools/build/v2 ;

but ultimately bjam gives me this error:

% bjam
notice: no Python configured in user-config.jam
notice: will use default configuration
C:/local/boost_1_54_0/tools/build/v2/build\project.jam:262: in find-jamfile from module project

hi,

have you placed user-config.jam in your %HOMEDRIVE%%HOMEPATH%
location, and configured Python inside it, e.g.

using msvc : 10.0 : : ;

using python
  : 2.7 #version
  : D:/Python27 # cmd-or-prefix
  : D:/Libs/Python273/include #includes
  : D:/Libs/Python273/libs #libraries
  ;

as described here:

http://www.boost.org/boost-build2/doc/html/bbv2/reference/tools.html
http://www.boost.org/boost-build2/doc/html/bbv2/overview/configuration.html
http://www.boost.org/boost-build2/doc/html/bbv2/overview/invocation.html

?

Hi,

Placing  user-config.jam in your %HOMEDRIVE%%HOMEPATH%
location, and configured Python inside it, is very crucial step.

I spent like 4 days while trying to build it without following this step.
Please see the tutorial with the link below:

Cheers,
Raghav

(Hope top-posting is OK on this list, sorry if not)

Thanks -- I had not seen those doc links before.  

I tried your user-config.jam (updated for my config), and bjam does find it, but still fails to find a Jamfile for the tutorial example.  I wonder if there is some problem with the Windows boost installer (exe); maybe I should build boost from source?

I notice that the Jamroot in the tutorial example has this:

 # Specify the path to the Boost project.  If you move this project,
 # adjust this path to refer to the Boost root directory.
 use-project boost
   : /local/boost_1_54_0 ;

if I modify that dirname, the error refers to a different dir.  And there is no Jamfile in that dir.

Thanks for all your help;

Hi Raghav; thanks for that link. In there, he does not use bjam to build the python extension dll; he creates a Visual Studio project and does it there. Is that the recommended method now? I thought I saw somewhere it is recommended to use bjam and most newbie questions come from not doing that. 

In any case, I can use bjam to build and test the tutorial example when it's inside the boost tree, but not when I move it outside -- I feel like I must be missing something simple.

Hi Gary,

You can forget bjam.
Just use b2 as written there in tutorial.
Just an additional comment, even if you are using x64 bit architecture, you
dont have to install 64 bit Python and 64 bit compiler for Visual studio.
Even if you use 32 bit Python and 32 bit Visual Studio C++ compiler, it
will work fine.

These instructions were written by my colleague and we worked together on
that, so please feel free to post some question if it doesn't work.

Cheers
Raghav

Have you tried pointing the use-project boost to the boost source
directory rather than the boost installation directory? I don't think
boost installs the projects, just headers and libraries.

Regarding your question, about building dll file, if you mean by
boost_python-vc110-mt-gd-1_54.dll
this dll (along with other dll and lib files) are generated after using
build with b2. You just need to place it in your output directory in Debug
folder.

I installed Boost using the Windows installer from http://softlayer-dal.dl.sourceforge.net/project/boost/boost-binaries/1.54.0/boost_1_54_0-msvc-10.0-64.exe; maybe that didn't come with source or something?  It only created \local\boost_1_54_0.  After running that installer I did still have to do the 
  bootstrap; .\b2 toolset=msvc
thing to get bjam.

And now that I look at that download URL, what Raghav says about using a 32-bit version might be more sensible; my python is stock 2.7.3 Windows 32-bit (not cygwin or anything weird) and I'm only looking to build extensions for a 32-bit python at this point.

I did download the source distribution, but it doesn't have a Jamfile in its root dir either.  Maybe I have to unpack it and run b2 to get that... I guess I'll try that next.

Hi Raghav; no, I seem to have that dll. I meant the dll that results from building the extension project itself -- I guess it's actually a .pyd; sorry for the confusion. 

Your link at garkavictor says to ignore bjam and b2 and just make a Visual Studio project to build the extension; I guess I will also try that next. (I am one of the maintainers of SCons, the python-based build tool; if I can make it build under VS I can probably also make it build under SCons, which would be cool.) 

Actually now that I am looking closely at your blog post, it is for going the other way ("embedding" rather than "extending") but I guess extending is similar, just make a DLL project and rename the output or something maybe?

I recommend you better use the source rather than some pre-compiled
binaries. I tried binaries and I had failed.  I use Python 2.7.3 and VS
2008. Actually Victor and I, we tried only for embedding since this was our
need. But extending should not be any different ( my guess)...please write
back when it works ( or doesn't) ..

SCons FTW! :-) 

I built from source and tried it all again with bjam; no luck, same problems. So I figured, how hard can it be, it's just a DLL after all (renamed to .pyd). And sure enough it's not that hard. Here's a SConstruct that builds the tutorial example, wherever it is (does not have to be in the boost tree). I'm sure this could be generalized, but it's good enough for me as is. 

# SConstruct for building boost python tutorial example 

import os 

boost_python_lib = 'boost_python-vc100-gd-1_54' 
boost_top = 'c:/boost' 
python_top = 'c:/python27' 

env=Environment(TARGET_ARCH='x86', 
CCFLAGS=['/MDd', '/DEBUG'], 
CPPPATH=[os.path.join(boost_top,'include/boost-1_54'), 
os.path.join(python_top, 'include')], 
LIBPATH=[os.path.join(boost_top, 'lib/i386'), 
os.path.join(python_top, 'libs')]) 
dll=env.SharedLibrary('hello_ext', 'hello.cpp', 
LIBS=boost_python_lib) 
env.InstallAs('hello_ext.pyd', dll[0]) 
# Copy the boost python lib into this dir so hello_ext will find it at runtime 
env.Install('.', os.path.join(boost_top, 'lib/i386', '%s.dll'%boost_python_lib))

Message-ID: <145099822.1677750.1381261728182.JavaMail.root@genarts.com>

Sorry if this is the wrong forum for pyplusplus questions; please feel free to tell me to post elsewhere if that's appropriate.


I have this legacy struct in foo.h that is used by some code I'd like to wrap:

struct S
{
  char name[128];
  char input_names[8][12];
};

If I run pyplusplus on it (cool tool, by the way), it generates a file called __array_1.pypp.hpp with a struct array_1_t in it. It uses that for input_names above, as here in the generated bindings.cpp:

    static pyplusplus::containers::static_sized::array_1_t< char[12], 8>
    pyplusplus_input_names_wrapper( ::S & inst ){
        return pyplusplus::containers::static_sized::array_1_t< char[12], 8>( inst.input_names );
    }

But the Windows compiler (Visual Studio 2010) won't compile that code:

cl /Fobindings-tmp.obj /c bindings-tmp.cpp /TP /MDd /DEBUG /EHsc /DPYTHON_EXT /IC:\genarts\sapphire /IC:\boost\include\boost-1_54 /IC:\python27\include
Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 16.00.40219.01 for 80x86
bindings-tmp.cpp
/tmp/__array_1.pypp.hpp(122) : error C2440: '=' : cannot convert from 'const char *const ' to 'char [12]'
        There are no conversions to array types, although there are conversions to references or pointers to arrays
        /tmp/__array_1.pypp.hpp(120) : while compiling class template member function 'void pyplusplus::containers::static_sized::array_1_t<TItemType,size>::set_item(unsigned long,const char *const )'
        with
        [
            TItemType=char [12],
            size=8
        ]
        bindings-tmp.cpp(26) : see reference to class template instantiation 'pyplusplus::containers::static_sized::array_1_t<TItemType,size>' 

The code in question is in the generated __array_1.pypp.hpp, abbreviated here:

template< class TItemType, long unsigned int size >
struct array_1_t{

    typedef BOOST_DEDUCED_TYPENAME boost::call_traits<const TItemType>::param_type param_type;
    
    typedef BOOST_DEDUCED_TYPENAME boost::mpl::if_c< 
            details::is_immutable<TItemType>::value
            , TItemType
            , param_type
        >::type reference_type;
...
    void
    set_item( long unsigned int index, reference_type new_value ){
        raise_on_out_of_range( size, index );
        m_data[index] = new_value; <<<<<<<<<<<<<<<<<<<<< COMPILE ERROR HERE
    }

So that kind of makes sense.  It doesn't make sense to pass a char[12] array into set_item and expect it to populate an element of m_data.

What should I do about this?  It turns out I don't really care about exporting that particular field to python; can I tell pyplusplus to ignore it somehow?  That struct does get used lots of other places though, if that matters.

I've always found that the easiest way but then I haven't used Windows

Hi folks; I hope someone can help with a problem I'm having.

I have Base and Other classes (sorry for the generic names), and Base contains a fixed-length const array of pointers to Others. I'm trying to expose Base to python.  I started with a pyplusplus run and hand-massaged the result, so it uses the autogenerated __array_1.pypp.hpp.  I've included my entire code, including my classes and the boost.python wrappers.

The problem is that boost.python fails to wrap the "others" member variable of Base; it ends up trying to cast an Other *const to an Other *.  At the end, I'll include the whole error message.  It seems like it doesn't propagate the constness through pytype_function, but I don't know enough boost to be sure of that. (This is on Windows 7, MSVC 10, boost 1.54.)

(I can't change the structure of the Base or Other classes much; they're from a larger system.)

Thanks in advance!

Wow, that's really not a lot to go on. Usually the mailing list would at
least want to know what you're trying to do, what versions of the OS and
compiler you're using and what specific command lines you executed -- plus
a small, self-contained source file that demonstrates the problem.

I have just one thing to say about LNK1104.

While building our own software, I have encountered so many spurious
LNK1104 errors that I've concluded it must be primarily due to Windows 7
failing to release file locks soon enough after program termination. I
finally got fed up and coded a retry loop into the script with which I run
builds. When the failure output contains "LNK1104," my script emits a
message and reruns the build command line. Usually that succeeds.

I may have an unusual Windows development environment. Certainly the
scripts we run on our build farm don't include automated retries, and yet
somehow we manage to produce Windows executables. I do have the impression
that our buildmeister manually reruns many Windows builds; I couldn't tell
you whether LNK1104 is the chief culprit.

So in the complete absence of any other actionable information, my only
advice is: try running your build again.

Subject: [C++-sig] ArgumentError storing and retrieving pointer in class:
	wrong type
In-Reply-To: <952684176.2469376.1382625944605.JavaMail.root@genarts.com>
Message-ID: <1075241311.2469541.1382626495347.JavaMail.root@genarts.com>

I recently posted an issue on StackOverflow about some Py++-generated code that didn't seem to work.  The question is at http://stackoverflow.com/questions/19461274/.

Simply, I have these classes:

struct classA {
  int intval;
  unsigned int bitfield_member:1;
};

struct Collection {
  classA * class_a_ptr;
};

and Py++ generates a wrapper for classA, and setter/getters for bitfield_member, but the problem seems to be that the getter for class_a_ptr (get_class_a_ptr) returns a classA *, not a classA_wrapper *, and that doesn't have the bitfield_member accessors, so doing this in python fails at runtime:

  coll=Collection()
  g = classA()
  coll.class_a_ptr = g
  print coll.class_a_ptr.bitfield_member <-- fails with ArgumentError, wrong type

The solution suggested in the SO question is to change the generated bitfield_member setter/getter to take an explicit classA * as "this".  My solution instead was to change get_class_a_ptr to return a classA_wrapper *, since it has the same data layout as classA.  (The answer in the SO article would be hard for me, since in my real case classA has hundreds of members and I'd rather not hand-edit them all.)

Either way, it seems py++ generates non-working code for this example.  See the SO question for complete details.  Roman, if you're reading this, I presume this is the best way to submit these kinds of issues?  I'm happy to post a bug report elsewhere if that's appropriate.

Thanks;
