Package: dpkg-dev Version: 1.22.21 Severity: important File: /usr/bin/dpkg-shlibdeps
Hi Guillem, for some back story please see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1111805#49 In https://salsa.debian.org/glibc-team/glibc/-/commit/5e3aa111654e9aad080881fb98f9e5b01b277857 (currently only available via Debian experimental), the duplicated paths for /lib were removed from ld.so.conf files. This triggered a build failure for ncl, hdf-eos5 and ruby-hdfeos5. All those packages link against libgctp and the build failures look similar: hdf-eos5: dpkg-shlibdeps: error: no dependency information found for /usr/lib/x86_64-linux-gnu/libgctp-2.0.0.so (used by debian/libhe5-hdfeos0t64/usr/lib/x86_64-linux-gnu/libhe5_hdfeos.so.0.0.0) dpkg-shlibdeps: hint: check if the library actually comes from a package dh_shlibdeps: error: dpkg-shlibdeps -Tdebian/libhe5-hdfeos0t64.substvars debian/libhe5-hdfeos0t64/usr/lib/x86_64-linux-gnu/libhe5_hdfeos.so.0.0.0 returned exit code 1 ncl: dpkg-shlibdeps: error: no dependency information found for /usr/lib/x86_64-linux-gnu/libgctp-2.0.0.so (used by debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGncl.so.1) dpkg-shlibdeps: hint: check if the library actually comes from a package dh_shlibdeps: error: dpkg-shlibdeps -Tdebian/libncarg0t64.substvars debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGgksPS.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGmisc2.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGllu.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGras.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGcgm.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGff.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGgksPDF.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGgksX.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libfftpack5_dp.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGnfpfort.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGgksCTXT.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGlluC.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGmp.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGmisc.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGgks.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGhlu.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGncl.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGctrans.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGmath.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGc.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGnfp.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGcn.so.1 debian/libncarg0t64/usr/lib/x86_64-linux-gnu/libNGictrans.so.1 returned exit code 1 dh_shlibdeps: error: Aborting due to earlier error make: *** [debian/rules:14: binary] Error 25 ruby-hdfeos5: dpkg-shlibdeps: error: no dependency information found for /usr/lib/x86_64-linux-gnu/libgctp-2.0.0.so (used by debian/ruby-hdfeos5/usr/lib/x86_64-linux-gnu/ruby/vendor_ruby/3.3.0/numru/hdfeos5raw.so) dpkg-shlibdeps: hint: check if the library actually comes from a package dh_shlibdeps: error: dpkg-shlibdeps -Tdebian/ruby-hdfeos5.substvars debian/ruby-hdfeos5/usr/lib/x86_64-linux-gnu/ruby/vendor_ruby/3.3.0/numru/hdfeos5raw.so returned exit code 1 dh_shlibdeps: error: Aborting due to earlier error make: *** [debian/rules:18: binary] Error 25 If you want to reproduce the problem, remove the line /lib/x86_64-linux-gnu in /etc/ld.so.conf.d/x86_64-linux-gnu.conf and try to build one of those packages in debian sid or trixie. It is unclear to me, if this is a problem in libgctp, dpkg-shlibdeps or the affected packages themselves. I decided to file it against dpkg(-shlibdeps) as it is the command failing. I chose severity important (as it makes packages FTBFS) and it probably should be bumped to RC once glibc with that change is uploaded to unstable. The setup of libgctp is a bit special as detailed in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1111805#69 As Aurelien pointed out, while special it should still be covered according to the dpkg-shlibdeps documentation but maybe it is hitting less tested code paths. Would very much appreciate your input on this matter.
