[gmx-users] Mopac gomacs installation

[Javier Cerezo]

Did you try --disable-shared? In recent versions of GROMACS shared 
libraries are the default but libmopac.a is static. I would expect a 
compilation error regarding this issue; does it come up when doing make?

You can also add --disable-threads as you cannot use parallelization in 
GROMACS with QM/MM.

I also had some troubles some time ago with GROMACS-MOPAC compilation. 
Finally, I succeed to install libmopac.a  myself with gfortran and it 
worked in my computer
