[gmx-users] mpi.h fatal error.

[Anna Vernon]

After a gazillion useful and draining installs and cmakes for a week 
now,I have this issue. My plan is to install gromacs 5.1.2 with a plumed 
patch, because no matter what I did to gromacs2016, it would not even 
recognise plumed although the patch had been applied. Anyhow,

/home/anna/Downloads/gromacs-5.1.2/src/gromacs/utility/gmxmpi.h:61:17: 
fatal error: mpi.h: No such file or directory
compilation terminated.
src/gromacs/CMakeFiles/libgromacs.dir/build.make:933: recipe for target 
'src/gromacs/CMakeFiles/libgromacs.dir/commandline/cmdlineinit.cpp.o' failed
make[2]: ***

Makefile:160: recipe for target 'all' failed

I have looked through the forum, nothing to solve this issue either.
