Re: [Bug-gnubg] compilation error: "'gl.h' file not found" on Mac OS X

[Daisuke Takahashi]

Hi,

I see. I found that, in macports environment, the libgtkglext (X11) links to 
macports' libGL. So the better choice is to add -I/opt/local/include/GL to 
CFLAGS instead of patching source files, is it right?
Thank you very much.

Regards,
Daisuke Takahashi
