Description Alfonse 2013-01-05 11:32:57 PST

In the .spec file, it defines GLhandleARB as `unsigned int` for all platforms. However, the MacOSX Cocoa header `gltypes.h` defines it as `void*`. This causes a conflict.

Both GLEW (https://sourceforge.net/p/glew/bugs/206/) and glLoadGen (https://bitbucket.org/alfonse/glloadgen/issue/33/mac-compilation-error) have encountered this issue, and simply ifdef-ing around `gltypes.h` is probably not a reliable solution.

You should get with Apple and figure out what they want their GLhandleARB to be defined as, and provide an appropriate #ifdef around it for other platforms.

Benj, could you verify this? I can work around it although I'd also
need to know a reliable preprocessor-level way of distingushing that the
header is being processed in a MacOS X environment where GLhandleARB
is defined differently than the GL spec says it is. Thanks.

Jon, #ifdef __APPLE__ should work fine for this.

Comment 3 Jon Leech 2013-06-15 13:29:29 PDT

Fixed in gl.xml & glext.h in Subversion.
