I suppose that using the '-multiply_defined suppress' flag might help
here, but then I won't know if I'm using the correct OpenGL libraries
(I'm not sure what might be different between the system and X11
versions). Has anyone else run into this problem and are there any
suggestions on what to try?
You need to remove the -force_flat_namespace flag, then the
multiply-defined symbols give ony warnings. I think you need to add some
-lXm flags at a couple of places, too, IIRC. I had been there some weeks
ago, but gave up after running into multiply-defined symbol errors later
on, even without the -force_flat_namespace flag:
gcc -g -O2 -L/usr/X11R6 -lXm -L/sw/lib -o clip clip.o clipoogl.o
clipmain.o ../../../../src/lib/gprim/stub/libstub.a
../../../../src/lib/oogl/wa/libwa.a
../../../../src/lib/camera/libcamera.a
../../../../src/lib
[...]
../../src/lib/oogl/lisp/liblisp.a
../../../../src/lib/oogl/refcomm/librefcomm.a
../../../../src/lib/oogl/util/libooglutil.a
/usr/bin/ld: multiple definitions of symbol _BezierReDice
../../../../src/lib/gprim/bezier/libbezier.a(bezdice.o) definition of
_BezierReDice in section (__TEXT,__text)
../../../../src/lib/gprim/stub/libstub.a(bezier.o) definition of
_BezierReDice in section (__TEXT,__text)
[and so on]
This is something more profound, because there really are two different
definitions of that symbol in two different libraries that are both
included on the linker line.
