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 DX Packages, which is subscribed to unity in Ubuntu.
