[gmx-users] Gromacs installation fails in CentOS 6.5

[Szilárd Páll]

Strange. That means the GROAMCS build system somehow does not get the final
link command right. Without investigating deeper, I'm not sure what would
be the solution.

I'd look a the actual link command that fails (make VERBOSE=1) and try to
see what and why is missing.

BTW, cmake should know that libgromacs.so is linked against the OpenMP
library, can you check what's in the libgromacs_LIB_DEPENDS variable in
CMakeCache.txt?
