Re: How do I include source files according to processor?



What you could consider is to #include the right file based on the target, e.g. in a file called machPatches.cpp you have:

#if defined( __ppc__ )
	#include "machPatchesPPC.cpp"
#elif defined( __i386__ )
	#include "machPatchesx86.cpp"
#else
	#error Unknown processor type
#endif

This is a bit cleaner than #ifs around the whole file. Not tried it but it should work!

Cheers,

Steve

Hi experts. Suppose I am building a universal binary target. In the PPC build, I want machPatchesPPC.cpp included in the build, while for intel, I want machPatchesx86.cpp (a processor-specific implementation of the same functions).

I know I can bracket each file with a processor-specific conditional, but prefer not to. Is there a cleaner way to bind a file to the compilation for a specific processor? Maybe some kind of per-file compiler flag?

Last time I asked about this, there wasn't. I forget how long ago that was but I really don't think it's changed in the latest (public) version of Xcode.


What I ended up doing was creating a ppc target and an i386 target and then lipoing the results together in a shell script build phase for the i386 target which depended on the ppc target. I also had to change the install name of the i386 target. That was because it was a framework in my case.
