> All packages that use glibmm would be required to be updated in Ubuntu to build with C++11 for this transition
It's the libstdc++ ABI break that causes the need for apps to be rebuilt. glibmm using C++11 in its API should not require anything to be rebuilt, and we'd definitely like to know if it does. I wouldn't call use of C++11 a transition. It's inconvenient for you that the ABI break (libstdc++) and API change (glibmm using C++11) happened at around the same time in Ubuntu, but now that you've now managed to rebuild (because of the libstdc++ ABI break), for instance, subtitleeditor, with glibmm 2.44 (without C++11), updating glibmm to 2.45/46 should have no effect whatsoever on how well the already-built subtitleeditor works. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to glibmm2.4 in Ubuntu. https://bugs.launchpad.net/bugs/1478367 Title: FTBFS: warning: identifier 'noexcept' is a keyword in C++11 [-Wc++0x- compat] Status in glibmm2.4 package in Ubuntu: Fix Released Bug description: Hi, while subtitleeditor builds fine with glibmm2.4 version 2.44.0-1 [1] it fails with 2.45.40-0ubuntu1 [2]. The error is: /usr/include/gtkmm-3.0/gtkmm/textiter.h:1231:5: error: 'exception_handlers_invoke' is not a member of 'Glib' The diff between both versions of glibmm2.4 show some changes with 'exception_handlers_invoke' [3] so I suspect the error comes from this changes.
