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

[kencu (Ken)]

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'
/opt/local/bin/gcc-apple-4.2 -Os -Wall -W -Iinclude -dynamic -fno-common -pedantic -fPIC -arch ppc -std=c89 -o bin/glewinfo tmp/darwin/default/shared/glewinfo.o -Llib  -lGLEW -arch ppc -framework OpenGL
Undefined symbols:

ld: symbol(s) not found
collect2: ld returned 1 exit status
make: *** [bin/glewinfo] Error 1

simple fix, in the end:

$ port -v installed glew
The following ports are currently installed:
  glew @1.12.0_0 platform='darwin 8' archs='ppc' date='2016-07-20T20:26:43-0700'
  glew @2.1.0_0 (active) platform='darwin 8' archs='ppc' date='2020-11-15T16:02:02-0800'

patch coming

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.
