After looking at SunOS-5.8, IRIX-6.5 and AIX-5.1 I got the impression
that the 'glext.h' header is a special feature of Mesa. But I found
something similar on Solaris in /usr/include/GL/glx.h, including an
explanation why the compiler on IRIX does _not_ fail.
SunOS-5.8:
/* Functions related to pbuffer extension */
extern GLXPbuffer glXCreateGLXPbufferSGIX(Display *dpy,
GLXFBConfigSGIX config,
unsigned int width,
unsigned int height,
int *attrib_list);
IRIX-6.5.22m:
/*
** Pbuffer (Pixel Buffer) extension
*/
extern GLXPbufferSGIX glXCreateGLXPbufferSGIX (Display *dpy, GLXFBConfigSGIX
config, unsigned int width, unsigned int height, int *attrib_list);

.... makes GCC on Solaris8 happy.
Can anyone suggest how to cast this into a compatible/portable shape ?
Thanks,
Martin.
