[gmx-users] mac OS Catalina segmentation fault

[Daskalakis Vangelis]

Dear all,
I am running Mac OS Catalina 10.15.1 (Xcode 11.2 11B52). I have
successfully compiled several versions of Gromacs (5.1.5, 2018.8, or
2019.4) patched with plumed (v.2.4.6 for 5.1.5, or v.2.5.3 for 2018/2019
versions). The compilations are completed without any errors, employing the
configuration:
# cmake .. -DGMX_BUILD_OWN_FFTW=ON -DGMX_MPI=on
-DCMAKE_INSTALL_PREFIX:PATH=/usr/local/gromacs -DCXX="$MPICXX"

For example Gromacs v. 5.1.5 (but the same is happening on the other
versions), I get segmentation faults, when I just run some tools, like:

[MacBook-Pro:33466] *** Process received signal ***
[MacBook-Pro:33466] Signal: Segmentation fault: 11 (11)

[MacBook-Pro:33466] *** End of error message ***
zsh: segmentation fault  gmx_mpi trjconv

switching MPI support on/ off on the configuration/ compilation stage does
not change the situation. Some tools are running smoothly, as editconf.
However others, have segmentation faults. Grompp is running on v.5.1.5, but
gives a segmantation fault on v. 2019.4.

I would appreciate some help,
thank you,
Vangelis.
