dear mahmoud,

your problem sounds like a PEBCAC-type problem,
and it is impossible to give other advice than
having a closer look at the installation instructions
and documentation, and then post to the _gromacs_
mailing list in case you need further help with that.

this is the NAMD mailing list and (most?) people here would
appreciate it, if you would only post questions that are
related to NAMD, its implementation, and use.
