Attached is the backtrace.
Maybe there is an issue with the libmwmvm.so library.
This library is not explicitly listed under the linked dependencies (ldd
./step-1),
but I do not know if this is the problem or not.
Maybe you have a better understanding of the backtrace.
Best,

In the debugger after you ran with the command »r« could you please try
to generate a back trace with »bt«?
(gdb) r
...
(gdb) bt
...
Best,
Matthias

See ldd.txt for the output of
$ ldd ./step-1
and gdb.txt for the output of
$ gdb ./step-1
Does this help?

The most likely issue will be a "symbol clash" either due to ABI
incompatible versions of the same external shared library linked into
the executable, or due to the matlab shared library you are linking
against containing these.
Can you send us the output of $ ldd executable (for a faulty one)?

May I have to pass some compiler flags to cmake, given that it works with the

I have no experience using Matlab, much less linking to it. I think you need

Hello everyone,
within my dealii program, I want to do some tasks using matlab functions,
i.e.,
I want to call matlab functions/scripts from within my dealii (.cpp)

To this end, I modified my top-level CMakeLists.txt,
included the headers
