  • empty ${shlibs:Depends} causing problems

    Hi Andreas!

    Yes, this is a known issue which luckily has already been resolved.

    I have no idea why this happened, but it caused qtbase-opensource-src
    to FTBFS [2], because cups wasn't detected.

    This was most likely triggered by this regression [1] in glibc which has already been fixed upstream and the current 2.24-5 Debian package includes
    the fix as well.

    Since libcups2 2.2.1-1 has the correct dependencies again, please give
    back qtbase-opensource-src.

    Yes, I will do that right now. I wanted to do that earlier, but I forgot
    when I went on vacation where I'm traveling a lot (still traveling).

    The other package I found lacking dependencies is libsndfile1 1.0.27-1,
    where the build log [3] has a similar warning:
    "dpkg-gencontrol: warning: Depends field of package libsndfile1: unknown substitution variable ${shlibs:Depends}"

    However, rebuilding that version locally produces a package with correct dependencies. So please binNMU libsndfile1 on sh4.

    Yes, because glibc is fixed now :). Will do an binNMU.

    There might be more cases, but I'm currently not aware of any others.

    Let me know if you find others.

    PS: I have acquired three additional hardware SH4 buildds while in Japan.
    Once I'm back in Germany, these will be set up as well.

    Hi,

    Something very strange is going on in the sh4 port:
    For some reason some binary packages don't have any dependencies,
    e.g. libcups2 2.2.0-2. The build log [1] says:
    "dpkg-gencontrol: warning: Depends field of package libcups2: unknown substitution variable ${shlibs:Depends}"

    I have no idea why this happened, but it caused qtbase-opensource-src
    to FTBFS [2], because cups wasn't detected.

    Since libcups2 2.2.1-1 has the correct dependencies again, please give
    back qtbase-opensource-src.

    The other package I found lacking dependencies is libsndfile1 1.0.27-1,
    where the build log [3] has a similar warning:
    "dpkg-gencontrol: warning: Depends field of package libsndfile1: unknown substitution variable ${shlibs:Depends}"

    However, rebuilding that version locally produces a package with correct dependencies. So please binNMU libsndfile1 on sh4.

    There might be more cases, but I'm currently not aware of any others.

    Best regards,
    Andreas

    That's good news. :)

    Thanks.

    I hope you're enjoying your vacation.

    I guess anything built between the upload of the broken glibc and the fixed
    one needs to be rebuilt.
    Looking at the Build-Attempted section of the sh4 buildd, almost all seem
    to be caused by this problem and should be given back, e.g.:
    * liblouisxml (glib2.0, already fixed)
    * sqlsmith (after postgresql-9.6 is rebuilt)
    * usbprog (after libgtk2.0-0 is rebuilt)
    * pdftk (after libgtk2.0-0 is rebuilt)

    PS: I have acquired three additional hardware SH4 buildds while in Japan.
    Once I'm back in Germany, these will be set up as well.

    Cool.

    Best regards,
    Andreas
