[PyOpenGL-Users] python2.3 - win2k - problems compiling

[Marcelo de F. R. <are...@ig...>]

Sorry if you have already answered this to another one, but I couldn't find 
anything on the list yet. 

when I'm executing "python setup.py install" in mingw using msvc6, the 
following error appear: 

C:\Arquivos de programas\Microsoft Visual Studio\VC98\BIN\link.exe /DLL 
/nologo /INCREMENTAL:NO /LIBPATH:../lib /LIBPATH:d:\progs\Python\libs

Studio\VC98\BIN\link.exe"' failed with exit status 1120 

I tried with mingw32, cygwin and none of then works (but the others I 
couldn't understand the error also). 

Thanks, 
Marcelo de Freitas Rigon

Okay, mingw32 and cygwin are both known to fail on building.  I haven't 
got time to track down why.  Anyone who wants to build and send in a 
patch set would be most welcome to try.

MSVC 6.0 is my primary development environment, so it's definitely able 
to build, so let's concentrate on that.  First, kill off any "source 
directory/build" directory so you know you're starting fresh.  Then make 
sure that you have GLUT compiled and the GLUT .h and .lib files in your 
include and library paths respectively.  Then make sure your OpenGL and 
GLU headers and libs are similarly in the include/library paths.  You 
can find instructions for this here:

http://pyopengl.sourceforge.net/documentation/installation.html

in the section "Building PyOpenGL".

To me, it looks as though you've got the GLUT headers available, but not 
the GLUT .lib files.

Only once you have those dependencies in the right places can PyOpenGL 
build.

Good luck,
Mike
