Re: [ESPResSo-users] problem fom installing the ESPResSo

[Jean-Noël Grad]

Hello,

If you get a segfault with other samples as well, it means something 
went wrong during compilation. If you compile espresso in debug mode 
(cmake3 -DCMAKE_BUILD_TYPE=Debug -DCMAKE_CXX_FLAGS=-Og ..), there should 
be a trace. Without it, it's very difficult to diagnostic a segfault. If 
you're familiar with debugging tools such as gdb, you may try to locate 
the source of the issue yourself, but it's tedious work.

Using our CentOS 7 Dockerfile 
(https://github.com/espressomd/docker/blob/master/docker/centos/Dockerfile-7) 
I set up two CentOS containers, one with openmpi and one with mpich 
(just by text substitution, got the 3.0.4 version). Both compiled 
espresso and ran the rigid_body.py just fine. There might be some 
interaction with your installed packages which we can't reproduce in our 
infrastructure.

Best regards,
JN
