Hi, We are further trying to make this recipe available by the package management `spack` in the PR: https://github.com/spack/spack/pull/13639, which leads to the errors reported in https://bugzilla-geant4.kek.jp/show_bug.cgi?id=2202 and https://bugzilla-geant4.kek.jp/show_bug.cgi?id=2201. If possible, it would be very nice to have documented in the `g4py` README.md file (i.e. instructions) the description of what dependencies that are considered optional to build Geant4 are non-optional/required for building g4py. This includes X11 and OpenGL, among other things such as qt, vecgeom, and motif. Thank you in advance for your help with this, Diana
thank you for your information. We will share the idea.
