>Summary: Python for BeOS/PPC Build Prob.
Initial Comment:
When trying to build python(2.1 final) normally under BeOS/PPC
5, Py_UCS4 does not seem to be defined in
Includes/unicodeobject.h
(This would seem to indicate that uint and ulong are shorter
than 4 bits!!!)
I'm guessing this is resultant of a problem elsewhere, but I'm
too clueless in terms of C(++) to work it out.

Okay - Finally got it fixed.
change line 1149 of configure from:
*.c | *.o | *.obj) ;;
to
*.c | *.o | *.obj | *.xSYM) ;;
(Okay, it was the prompt from GvR that made me really get down to
it)
Anyway, the -g flag to mwcc causes the debugging info to be put into
a *.xSYM file, which the configure script seems to think is the
required extension for an executable (there is none under BeOS).
Since the conftest progs for sizeof(type) have a -o conftest.xSYM,
and the line that runs them just has a `conftest >...`, the compiled
programs do not get run, so the size defaults to 0.
Simple.
Now I just need someone to commit this to the cvs tree...:-)

I'm afraid it's up to Matthew to figure out why the
configure script calculates zero object sizes. Sorry...
(At least try Python 2.1.1, although it may not make a
difference.)

Assigning the bug report back to None -- someone with more knowledge about autoconf should take a look at this
one. (It is not Unicode related.)

Here is the crux of my recent communications with Marc-Andre:

Interesting: the compiler chokes on the missing return statement
in the test program rather than some other error. This is clearly
an autoconf bug and I'm not sure whether it can be fixed in
Python.

I've uploaded Matthew's config files to SF. Perhaps some
Metroworks wizard could also take a look at these ?!

Sorry, I've been on holiday:-)
Donn Cave gave me a patch that allows BeOS to build it, so I'll send
it along with the config.* files...
(I've zipped them up, but I fear they will not upload with my
browser.)

Matthew, if you can not help us here, we won't be able to
resolve the problem.
Please send us the config.* files, so that we can check
where the problem originates.

Hmm, this seems to indicate that the autoconf generated
configure script doesn't work right on BeOS. Could you
attach the config.* files to this bug report ? Perhaps we
can find the cause of configure failing on BeOS.
Thanks.

okay, the config.h file is autogenerated - and all of the SIZEOF_xxx
constants are set to 0.
That's bad, huh?

Looking at unicodeobject.h:
/*
* Use this typedef when you need to represent a UTF-16
surrogate pair
* as single unsigned integer.
*/
#if SIZEOF_INT >= 4
typedef unsigned int Py_UCS4;
#elif SIZEOF_LONG >= 4
typedef unsigned long Py_UCS4;
#endif
it seems that SIZEOF_LONG and/or SIZEOF_INT are not defined
in your config.h file. Does the BeOS-port have its own
special config.h file or is the file generated using
autoconf ?
