[gmx-users] gromacs installation

[roshanak starlight]

hello
i try to install gromacs in my laptop with this cpu :AMD Dual-core
processor E-350 and Linux operating system ubuntu 14.04
i installed gromacs-5.1.2  and gromacs-5 but both of  these versions get
error about grompp .and installation from software center (gromacs-4.5.6)
get this error: illegal instruction core dumped .
Who knows what's the problem?

one told me that :I think you would run gmx under admin or force UBUNTU to
set gromacs in your path
what shuld i do?
