cross compiling
 

I want to cross compile some c++ code from linux to mac os x(10.3). I've seen things about doing it with gcc, but I can't find what exactly I need because there are so many options. More specifically the compilation will go onto an iBook G4.

I don't know much about compiling, but i do this:

before ./configure, i export some environment variables like:
export CFLAGS="-O3 -march=athlon-xp -mcpu=athlon-xp -fomit-frame-pointer"
then i do:
./configure CFLAGS="-march=athlon-xp -O3 -pipe -fomit-frame-pointer"
then make
