If the ABI will change with each new upstream version of g++, and the library soname / package name should be changed at the same time, then these packages *should* have build-dependencies on a specific version of g++, to avoid accidental ABI incompatibilities. > Packages in main affected are: > dbus-cpp > libcolumbus > firefox > mir > process-cpp > libreoffice (only the clang plugin which is not built) > qtbase-opensource-src > unity Thanks for researching this! Not all of the packages in the phone are in main. Can you do the same review for the set of packages that are in the ubuntu-touch seed? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to dbus-cpp in Ubuntu. https://bugs.launchpad.net/bugs/1329089 Title: g++-4.9 binary incompatibilties with libraries built with g++-4.8 Status in “dbus-cpp” package in Ubuntu: Confirmed Status in “firefox” package in Ubuntu: New Status in “gcc-4.9” package in Ubuntu: Confirmed Status in “gcc-defaults” package in Ubuntu: Fix Released Status in “location-service” package in Ubuntu: Invalid Status in “mir” package in Ubuntu: New Status in “process-cpp” package in Ubuntu: New Status in “qtbase-opensource-src” package in Ubuntu: New Status in “unity” package in Ubuntu: New Bug description: The location-service 0.0.3+14.10.20140512-0ubuntu1 package in utopic, when rebuilt against libdbus-cpp3 3.0.0+14.10.20140604-0ubuntu1 (built with gcc-4.8) and with current gcc-defaults (which makes g++-4.9 the default), fails the package build in its test suite. 2/14 Test #2: acceptance_tests ..................***Failed 30.54 sec DBus daemon: unix:abstract=/tmp/dbus-HdW1T5UHNB,guid=188551aa5d797b663dade1425398d71b task-0: Started with PID: 13031 task-0: [==========] Running 2 tests from 1 test case. task-0: [----------] Global test environment set-up. task-0: [----------] 2 tests from LocationServiceStandalone task-0: [ RUN ] LocationServiceStandalone.SessionsReceiveUpdatesViaDBus ** (dbus-test-runner:13025): WARNING **: Timing out at maximum wait of 30 seconds.
