The EXT versions were from the OpenGL 1.0 days and aren't exported by
Apple OpenGL.
If this is true, then why are they defined in the GL/gl.h and GL/glext.h
header files? And why are they in XFree86-4.3.0?
I don't know much about OpenGL, but I just had a look at the geomview
sources. It has the following interesting code:
#if defined(sgi) || defined(GL_EXT_texture_object) /* Might our -lGL know about
EXT_texture_object? */
/* Since the SGI compiler/linkers seem to know about #pragma weak, but
* others might not, compile in EXT_texture_object support if:
* - we're on an SGI; even if compiled under Irix 5 (no EXT_texture_object),
* we might be run under a later version that does support it, and
* the "#pragma weak" lets us test at run time whether the library
* supports it;
* - or, if we're on a system that claims to support it at compile time,
* we'll just hope that that system also supports it at run time.
*/
The latter situation seems to be Apple's problem here.
