I've been toying around with some Project Euler problems and naturally am running into a lot that require the handling of bigger than long long type numbers. I am committed to using Cocoa and Objective-C (I need to stay sharp for work) but can't find an elegant way (read: library) to handle these really big numbers.
I'd love to use GMP but is sounds like using it with Xcode is a complete world of hurt.
Does anyone know of any other options?
If I were you I would compile gmp outside XCode and use just gmp.h and libgmp.a (or libgmp.dylib) in my XCode project.
