The environment-file 99geant which is generated during src_install if USE=data is enabled contains much more than just environment variable assignments. This breaks env-update and the file is ignored. I think "G4INCLUDE="/usr/include/Geant4"" should be added, and apart from that only the assignments in the block "Resource file paths" should stay in there, with removed "> /dev/null" which is somehow in there. Accomplishing this needs some additional sed magic in the ebuild-src_install-phase: sed -n "s,export \(G4.\+DATA=\"\).*\(/share/Geant.\+/data/.\+\) > /dev/null ; pwd\`,\1${EPREFIX}/usr\2,p" This works for me, an additional echo "G4INCLUDE=\"/usr/include/Geant4\"" >> 99geant should do the rest. Reproducible: Always
Created attachment 336268 [details] Geant 4.9.6 with the sed-line in src_install patched as described I added the ebuild with the change to the sed-line in src_install applied, it works fine for me. I did NOT add G4INCLUDE to the environment file, because I realized this should not be necessary (geant4-config should be used by everything linking against geant4).
