A few notes to use openEMS with Octave:

• opencv4 contains a file named hdf5.h and openEMS's setup fails. You need to patch setup.m present in /usr/share/openEMS/matlab with

22c22
<         [res, fn_h]  = unix('find /usr/include -name hdf5.h | sort -r | head -1');
---
>         [res, fn_h]  = unix('find /usr/include -maxdepth 1 -name hdf5.h | sort -r | head -1');

• To include openEMS's matlab path run the following commands on octave shell

# addpath('/usr/share/CSXCAD/matlab');
addpath('/usr/share/openEMS/matlab');
savepath
exit

Then you need to build the dynamic-load module

sudo chmod o+w /usr/share/openEMS/matlab
octave --eval setup
sudo chmod o-w /usr/share/openEMS/matlab

Now you can use octave as always.

@ChRen What problem are you having? I just successfully completed rebuild in a clean chroot.

@xiota. Could you find the time to patch the package?

I'm having issues building it

Many thanks @xiota & sorry for the delay! I have integrated your proposed changes. Are you interested in taking over ownership of the package so you can get issues fixed faster (I'm not a regular openEMS user currently)?

fixed, thanks!

The PKGBUILD is missing depends for fmt and verdict. Build fails with:

[100%] Linking CXX executable openEMS
/usr/sbin/ld: warning: libfmt.so.10, needed by /usr/lib/libvtkFiltersGeneral.so.1, not found (try using -rpath or -rpath-link)
/usr/sbin/ld: warning: libverdict.so.1.4, needed by /usr/lib/libvtkFiltersVerdict.so.1, not found (try using -rpath or -rpath-link)

unless you add fmt and verdict as depends

Seems to depend on https://archlinux.org/packages/community/x86_64/pugixml/
