Need to find a C++ library

I'm doing a bit of research into some number theory and I require the ability to do simple arithmetic with large integer numbers (up to 2048 bits).

Does anyone know of any simple-to-use large integer libraries? All the ones I've downloaded so far won't compile (could be my compiler's too old or I'm not implementing them properly, I'm a bit of a programming noob)

I only need addition, subtraction, multiplication and modulos operators

You could always convert those integers into a larger number base.

MS Visual C++ Express edition comes with a very nice library, not sure if it has what you want but its worth checking out.

Hm, well I used this class but it is written for C#.

Take a look at Boost's BigInt implementation - it is still in the sandbox but AFAIK it should still work well

EDIT: Also, take a look at GMP or NTL
