[gmx-users] Re: Error of installing gromacs v4.5.4

[Szilárd Páll]

Hi,

That compiler is ancient (thought it might have SSE2 support) as well
as the OS, I guess (RHEL 3?). Still, the CPU does support SSE2 so if
you can get a gcc 4.1 or later on it you should still be able compile
and run the code without a problem.
