@gpettinello and @carlosal1015 I've added both of you as co-maintainers.

I am offer as volunteer to (co)maintain the package as doing with gmsh-bin.

@gpettinello If you are interested in maintaining the package I can orphan it. I don't have much time anymore.

Sorry for not answering the messages, I've been away for a while.

In package():

echo 'export PYTHONPATH="/usr/share/gmsh/api/python/:$PYTHONPATH"' > "$pkgdir/etc/profile.d/gmsh.sh"
echo 'setenv PYTHONPATH="/usr/share/gmsh/api/python/:$PYTHONPATH"' > "$pkgdir/etc/profile.d/gmsh.csh"

@gborzi I'm ready to submit the updated PKGBUILD but I'm not allowed to do it. Please could you add me in the list of contributors or could you update yourself:

Hi, I would like to ask if is possible to add as dependency explicitly the new package (3 days ago) med-openmpi since by default is installing med otherwise pacman always ask

:: Replace med with community/med-openmpi? [Y/n] 
resolving dependencies...
looking for conflicting packages...
:: hdf5-openmpi and hdf5 are in conflict. Remove hdf5? [y/N]

No. I modified the PKGBUILD and it compiles flawlessly Need to look how to submit the new PKGBUILD

Is there a reason why this is not updated to 4.10.5?

@drwells If ENABLE_SYSTEM_CONTRIB is disabled the compilation "prefers" the bundled software over that already available in the installation.
