Lots of errors in the build.log related to compiling C++11 code (included from libsigc++) without enabling C++11. Reproducible: Always Steps to Reproduce: 1. emerge =dev-libs/libsigc++-2.6.2 2. emerge =dev-cpp/glibmm-2.44.0 Actual Results: Compilation errors. Expected Results: Not sure. Either blocked it at the ebuild level if they are fundamentally incompatible, or enabled C++11 if that is a reasonable step in this case.

Created attachment 423410 [details] build log with errors related to C++11
you need to use glibmm-2.46
(In reply to Pacho Ramos from comment #2) > you need to use glibmm-2.46 Well, I think that's a bit of a hasty reply because actually what I needed to do was downgrade libsigc++ back to 2.4.1. (I can't remember why I had it keyworded in the first place.) Anyway, doesn't really matter, I guess the moral of the story is that when you keyword packages you run this risk of incompatibility.
hasty? Well, sorry if it sounded like that... I was at job and simply looking to a few bugs on a small gap that I was free In summary -> Either you run all the "mm" part from testing or from stable, but mixing them can lead to issues like this ;) See you
