Sparse matrix library

Asuralm

Hi all:

I need to solve a sparse linear system, I found the iterative methods library which probably fit my requirement. But I couldn't find any good matrix library to work with IML++. The best choice should be Sparse++ but it requires a very old compiler which is gcc 2.7. something like that. The gcc compiler in our lab is about 4.3, so I can't compile the library sparse++.

Does anyone know is there any other good matrix library which meets the requirements of the IML++ please???

Thanks
