Bug 123438 – nvidia-glx-1.0.6629-r6 fails to compile when glxext.h included

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Michael C. Martin 2006-02-19 20:51:39 UTC]

While compiling d2x-xl from plain source, the compile failed immediately with

/usr/include/GL/glxext.h:394: error: parse error before '*' token
/usr/include/GL/glxext.h:394: error: `__GLXextFuncPtr' declared as function returning a function

The 'parse error' appears to be because GLXextFuncPtr is only defined if GLX_ARB_get_proc_address is yet undefined, but code conditional on the undefined-ness of GLX_VERSION_1_4 also uses the type.

Thus, if GLX_ARB_get_proc_address is defined but GLX_VERSION_1_4 is not, the typedef will fail.

The most straightforward fix is below:

--- glxext.h    2006-02-19 20:55:59.000000000 -0800
+++ glxext-orig.h       2006-02-19 20:51:59.000000000 -0800

This works fine if you use the standard glxext.h rather than nvidia's.  This is the default in eselect-opengl.
