As Dan has already said, Amber builds fine with GCC 4.4.6 (that's what I've
used on my machine for ages). I've also tested, at one point, 4.3, 4.4,
4.5, and 4.6 all on the same machine -- all of which worked.
The trickiest thing about using multiple GCC installations on the same
machine is how to properly toggle between them (this is what you're having
troubles with, I think). The operating systems where I regularly switch
GCC versions (Mac OS X and Gentoo) have scripts that do this for you. If
this is the case for you, then use those scripts. If it's not, you're
probably best off using only the version that came with your OS unless you
really know what you're doing.
All that said, the original error looks like an issue with your CUDA
compiler, not your C/F90 compilers, so we can't help you unless you provide
information about your CUDA setup.
HTH,
Jason
