On a relevant note, today I tested some experimental packages built with the new C++11 ABI. [1] Judging by this test run, we should be able to do the rebuilds, in a mostly automated way, within about 3 days once we decide to implement the ABI change. [2] My regular Xfce desktop seemed to work fine (incl. Firefox and Chromium). I also tried KDE's Plasma desktop with no issues. I did, however, see two crashes listed in coredumpctl but I didn't notice them during normal usage, probably because they happened at program termination. [3] We'll certainly need to look into these crashes at some point. Disclaimer: As mentioned in the README.txt file, these builds should never be installed on a live system; I was just lazy and tried them anyway. :P [1] http://nymeria.archlinux.org/cxx11abitest/README.txt [2] https://github.com/foutrelis/arch-rebuilds [3] http://pkgbuild.com/~foutrelis/backtraces/
