[LLVMdev] Using LLVM JIT inside a Cocoa application

[Camille Troillard]

Bonjour Jean-Daniel,

I didn't know about the clang Xcode project, and indeed it works very naturally.
It seems the key to successfully build a project within Xcode is to set :

GCC_PREPROCESSOR_DEFINITIONS = __STDC_CONSTANT_MACROS __STDC_LIMIT_MACROS=1

I was fearing the makefiles were involving more work behind the
scenes, but that's not true: include the headers, libraries, and set
the C++ macros.

Thanks for the info!


Best,
Cam
