ccx_preCICE just crashes with segmentation fault #53

Closed BenjaminRodenberg closed 3 years ago

If I run ccx_preCICE -i somenonsenseinput it just crashes with the following error:

$ ccx_preCICE -i somenonsenseinput

Note that the vanilla CalculiX (I used the version installed via apt) gives me a different error which is for a user much easier to understand:

$ ccx -i somenonsenseinput

Some more information on this issue:

I've built the adapter on my system installing the required dependencies from apt. It's a Ubuntu 20.04 system. If I run the same command on the docker container precice/calculix-adapter-ubuntu1804.package-develop the error message is good.

I used precice/precice-ubuntu2004.package-develop as a basis for building the CalculiX adapter with this modified Dockerfile.calculix-adapter. Again: The error message looks good. So it looks like there is a system specific problem on my computer.

$ docker build -t benjaminrodenberg/calculix-adapter-ubuntu2004.home-develop -f Dockerfile.calculix-adapter .
$ docker run -ti benjaminrodenberg/calculix-adapter-ubuntu2004.home-develop

I ran a make clean and another make and now everything seems to work. So: Obviously false alarm.
