  • [RFC] Removing support for GCJ and GCJFLAGS from dpkg?

    From Guillem Jover@21:1/5 to All on Thu Aug 31 02:30:02 2023

    Hi!

    While going through the supported compilers and build flags recently,
    I noticed that dpkg-buildflags and the various dpkg Makefile fragment
    files still have support for gcj, but that compiler seems to have
    stopped being maintained some time ago. According to Wikipedia (<https://en.wikipedia.org/wiki/GNU_Compiler_for_Java>) the final
    release was in 2018, and we do not even have it in Debian anymore.

    So I guess it should be fine to rip that off? A quick codesearch.d.n
    didn't reveal much of a usage. But I'd like to hear whether this would
    break or disrupt things, before I consider removing these.

    Thanks,
    Guillem

    No concerns from the Debian Java team. I can't imagine any breakage,
    but if there is any fall-out, it would be due to cruft that we should
    clean up anyway. The dependency on gcj-jdk was dropped from javahelper (src:javatools) for buster [0].

    Thanks for catching this.

    Cheers,
    tony

    Yes go ahead, GCJ is long dead and gone, you can remove the remaining references safely.

    Thanks both for the confirmation! I've queued the attached patch which
    will be included in my next git push targeting dpkg 1.22.1.
