--- Begin Message ---Package: libgraphicsmagick++-q16-12 Version: 1.3.31-1 Severity: important Important due to RC Policy "Shared library packages must include correct shlibs files". There was an ABI change between libgraphicsmagick++-q16-12 versions 1.3.30+hg15796-1~deb9u2 and 1.3.31-1 but the shlibs file was not changed. As a result, some dependent packages like python3-pgmagick don't get a strict-enough dependency from dpkg-shlibdeps and can end up in a broken state when built with the newer library but installed with the older. Steps to reproduce: 1. Ensure you have the stable repo in your apt sources. 2. Install the older library: apt install libgraphicsmagick++-q16-12=1.3.30+hg15796-1~deb9u2 3. Install python3-pgmagick from testing/unstable: apt install python3-pgmagick=0.7.4-1+b2 4. Try to load the library (which has an unconstrained dependency on libgraphicsmagick++-q16-12): echo 'import pgmagick' | python3 Observation: failure to load libGraphicsMagick++-Q16.so due to missing symbol: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python3/dist-packages/pgmagick/__init__.py", line 1, in <module> from pgmagick import _pgmagick ImportError: /usr/lib/python3/dist-packages/pgmagick/_pgmagick.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _ZNK6Magick5ColorcvNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEEv This is because the python3-pgmagick library was built with the newer GM++ library, which declares the same soname/shlibs as the older library, but the exported symbols differ because of the libstdc++ C++11 ABI change <https://wiki.debian.org/GCC5#libstdc.2B-.2B-_ABI_transition>. You can compare the exported symbols from each version of libgraphicsmagick++-q16-12: readelf -s -W /usr/lib/libGraphicsMagick++-Q16.so.12 | awk '{ print $8 }' | sort -u Diffing the symbol lists, you can see some changes related to the C++11 ABI change: -_ZNK6Magick5ColorcvNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEB5cxx11Ev +_ZNK6Magick5ColorcvNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEEv There are also some other changes not necessarily related to the libstdc++ ABI change. So I think the soname should have been incremented in version 1.3.31-1 to prevent packages getting dependencies that are too weak and allow broken installations. Incrementing it now and rebuilding all dependent packages would fix them. -- System Information: Debian Release: 9.6 APT prefers stable APT policy: (990, 'stable'), (500, 'stable-updates'), (500, 'unstable'), (500, 'testing'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.18.0-3-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages libgraphicsmagick++-q16-12 depends on: ii libc6 2.27-8 ii libgcc1 1:8.2.0-10 ii libgomp1 8.2.0-10 ii libgraphicsmagick-q16-3 1.3.30+hg15796-1~deb9u2 ii libstdc++6 8.2.0-10 libgraphicsmagick++-q16-12 recommends no packages.
