Package: ftp.debian.org Severity: normal hepmc does not build with gcc-5 or later (see bug#777901), and thus requires a gcc 4.x to build, which has been last shipped in Jessie. This problem has been forwarded upstream, but hasn't been fixed yet. This problem has been there for almost 3 years and nobody seems to care about it.
In addition to that hepmc build-depends on a package which is not anymore in the archive (see bug#867090). Again nobody seems to care about that, even if the bug is "only" 6 months old. This package hasn't been part of the Stretch release and hasn't seen any Debian upload or upstream activity for more than 5 years. I therefore recommend to just remove this package from the archive. If someone finally wants to maintain it and if upstream restarts its activity, it's always possible to get the latest version of the package from snapshot.debian.org. -- debian-science-maintainers mailing list debian-science-maintainers@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/debian-science-maintainers
