Hi, I already suggested that you stop using your root account for everyday tasks. You need it for "make install" only.
Probably your problem is that you are using an old build tree that was using some other compiler. Make a new build tree if you're changing your tool chain. Or better still, start by unpacking the tarball as a normal user, use scl as above, and then follow the GROMACS installation instructions. No root until "make install"! If that doesn't work, then I can probably only suggest that you've broken your Linux installation in some way and should (unfortunately) install a new one. :-( Mark On Thu, May 4, 2017 at 9:04 AM RAHUL SURESH <[email protected]> wrote: > I am trying all possible ways to install Gromacs and I end up with errors. > I have updated my OS, installed GCC 5.3 manually and devtoolset-4.
