[Distutils] Help: request for assistance with PyOpenGL distribution using dis tutils on NT

[Mike Fletcher]

Background:
	While stuck on my real work, I'm trying to get a PyOpenGL
distribution (1.5.6alpha1 from CVS) working using distutils.  Rene Liebscher
kindly created an installation script that seems to work for him on Win32
for the 1.5.5 PyOpenGL, and for Jason Petrone (on Linux) using the 1.5.6
source from CVS.  I'm working on NT 4.0 sp3, using VC++ 6.0sp3, (I get
similar effects on Cygnus, but since I'm not sure the package builds under
that compiler I'm not focussing on it yet).
	When trying to build, I get a long set of errors (see below), the
elimination of which is well beyond my meagre VC++ or distutils skills to
fix.  According to MSDN, the problems I'm getting are normally caused by
having a C++ file compiled as a C file.  To get around it, you apparently
put an ifdef at the top and bottom of the file, but the file concerned
(GL.h) has this check, and still reports the errors.  I'm assuming there's
some flag that needs to be set somewhere, but I don't know what it is.
	Note: everything builds fine using the old setup script for the
latest CVS version on this machine (the one for which I'm trying to get a
distutils script).

D:\bin\lang\studio\VC98\BIN\cl.exe /c /nologo /Ox /MD /W3 /GX -Isrc
-ID:\bin\lang\Python\Include /Tcsrc/_glumodule.c
/Fobuild\temp.win32\Release\src/_glumodule.obj

Doesn't work.  The GUI under the old BUILD.py uses:

/nologo /MD /W3 /GX /O2 /Ob2 /I "D:\bin\lang\Python\include" /D "WIN32" /D
"_WINDOWS" /D "NDEBUG" /Fp"tmp\./_glu.pch" /YX /Fo"tmp\./" /Fd"tmp\./" /FD
/c 

and works fine.  GL.h has the following code near the top (and close at the
bottom):

#ifdef __cplusplus
extern "C" {
#endif

Which, according to MSDN, should avoid the errors, but doesn't seem to.
Here's the output from running setup.py build...

... (100 errors, then stops due to having so many)

Does anyone have any suggestions on how to fix this (keeping in mind that
I'm not a C/C++ programmer, so the instructions should be pretty basic)?
Thoughts appreciated,
Mike
