[gmx-users] Gromacs Installation troubles

[Nicholas Geraedts]

Mark - I've followed the instructions on the wiki. The last step says to
email the mailing list, as I have done. I'm not sure about your comment for
not needing a complete make if we're looking for MPI. There are situations
where the program will be used in single-processor mode, as well as MPI. I'm
not too concerned with the time it takes to compile all of this (it's only
about 8 minutes for the whole lot).

Jussi - I'm trying to compile the packages myself since the pre-made RPM's
don't seem to install the libraries needed. Furthermore, the LAM RPM would
constantly complain about not being able to find gcc-g77 - a package found
in CentOS4 but not CentOS5 (it's now referred to as compat-gcc-34-g77 - the
names don't agree so rpm complains). Also, installing LAM from yum fails to
put the required binaries where they belong! There's no lamboot, mpmirun,
lamhalt, etc to be found anywhere in the path. I've found that it's often
much less of a headache if you can find the source and start from scratch
(this is the FreeBSD child in me talking).

My main problem so far is that the library for GSL is installed in the wrong
location and that mdrun_mpi doesn't seem to have been compiled. If the
source is provided, it should be possible to compile it into a functional
program...
