glew @2.1.0: Undefined symbols: "_CGLReleaseContext" on Tiger

Keywords: tiger Cc:
Port: glew


It may be a stretch, but I thought I would try glew on Tiger PPC.

I got to here:

src/glewinfo.c:16748: warning: implicit declaration of function 'CGLReleaseContext'

I slightly modified the Makefile patch, to remove -pedantic and thereby remove hundreds of warnings from gcc about this:

src/glew.c:12151: warning: ISO C forbids conversion of object pointer to function pointer type

One more little thing needs to be done on Tiger, to change the glew.h header to include AvailabilityMacros.h instead of Availability.h.
