[glewpy-users] Re: Unresolved external error when building glewpy 0.7.2

[Charles M. <cm...@in...>]

With windows you need to also specify opengl to link against.  Try this.

c:\Python24\python.exe setup.py build_ext -l opengl32 bdist_wininst

I am due for a minor release anyway, so I will post windows binaries 
here soon.  You should try the new pyrex 0.9.4.1 too.
