Comment 1 Fredrik Lingvall 2022-10-09 17:06:00 UTC
It looks like the file is installed in /usr/lib64/ (by cmake) and not where python can find it. I tried something like:

src_install() {

	# The file is installed in /usr/lib64/ (by cmake)
	# and not where Python can find it
	if use shared ; then
		insinto /usr/lib/python3.10/site-packages
		doins api/
in an modified ebuild (I guess one should not hardcode the install paths but I do now how to set the site-packages path for the current Python version).

NB. The api/ is build when setting USE=shared and the python stuff which is enabled when gmsh is build with USE=python is the private (undocumented) python API which is a bit confusing. My guess is that USE=python should imply enabling the api/ (and not internal python APIs used mainly for the developers of gmsh?).
