On some related project, I need to use the following options to gcc to
make it work on Mac and in python:
cython osmesa.pyx
gcc -Wfatal-errors -fPIC -I$(PREFIX)/include/python2.5 -c -o osmesa.o
osmesa.c
gcc -Wfatal-errors -fPIC -I$(PREFIX)/include -c -o osdemo.o osdemo.c
gcc -Wfatal-errors -bundle -flat_namespace -undefined suppress -o
osmesa.so osmesa.o osdemo.o -lOSMesa -lGLU -lGL
Then everything works as expected. Could some Mac user confirm, that I
am doing things right? Of course, if I use distutils, it will do
things for me, but I need to figure out how to use plan gcc, so that I
can figure out a fix for cmake.
The first 3 lines are standard, however the last line is new to me.
"-undefined suppress" is necessary so that gcc doesn't complain about
missing Python symbols (that don't matter since the module is imported
in python)
"-flat_namespace" is necessary with the above option otherwise gcc complains
"-bundle" this creates the right dynamic library. the other options
are "-shared" and "-dylib", but both of them result in "Bus error"
when I try to import he module from Python.
