Since we're compiling PPC 10.2 specific versions, we don't want to overwrite our regular libraries. I went with /opt/1028libs/. Just set this with the --prefix option to the ./configure script, for all the libraries you're including. Do this, and make sure you've defined the above environmental libraries both when you do ./configure and when you do make, and you should be set. For some of the libraries you might also need to use the --host=powerpc-apple-darwin option when running the ./configure script. | ||
To compile the SDL library (and maybe some of the other libraries) you will also need to set CPPFLAGS to a slightly different value than what is written above: | |||
export CPPFLAGS="-DMAC_OS_X_VERSION_MIN_REQUIRED=1020 -nostdinc -I$SDK/usr/include/gcc/darwin/3.3 -isystem $SDK/usr/include -arch ppc -F$SDK/System/Library/Frameworks" | |||
