MPI support on Ubuntu 24.04 -> error: ‘parseCommandLineArgument’ is not a member of ‘openEMS’

[davidkirkby]

I've tried to build openEMS by cloning the repository on a Ubuntu 24.04 system. After a lot of messing around I managed to install enough packages to get it to build with these options.

./update_openEMS.sh  --with-hyp2mat --with-CTB --python   --njobs=30  /opt/openEMS
<snip>
Have fun using openEMS

but the MPI interface will not build if I try that.

`./update_openEMS.sh   --with-MPI  --njobs=30  /opt/openEMS`
<snip>
build incomplete, cleaning up tmp dir ...

The error seems to be

[ 67%] Building CXX object CMakeFiles/openEMS.dir/FDTD/extensions/operator_ext_excitation.cpp.o
/mnt/ramdisk/openEMS-Project/openEMS/FDTD/openems_fdtd_mpi.cpp: In member function ‘virtual bool openEMS_FDTD_MPI::parseCommandLineArgument(const char*)’:

Any suggestions?

Please just build without MPI, it is difficult to use at best and very useless in any case and should be removed at some point in the future...

Thank you.
