Hi Mahdi,

DIP isn't built for any particular architecture. It should build on both
32-bit and 64-bit architectures. My iMac is 64-bit and it builds fine
there. If you can post the OS X version you're using, the compiler and
version, and the exact sequence of commands, etc., we can try to get it
sorted out.

Cheers,

Ted
