Ubuntu LTS 14.04 has 4.8 as the default compiler.

Someone / the wiki claimed 2017 is already working, which is a difference to the previous 2015 bump, which apparently took some time to fix the fallout of the update. > * For --enable-compiler-plugins, Clang 3.4 > (<https://cgit.freedesktop.org/libreoffice/core/commit/?id=733198de1b7fc3907609217147704f493f6146e6> > "Remove support for Clang < 3.4") > > The latest version is Clang 4 (just released the other day).

Ubuntu doesn't have any official clang compiler, but provides a clang-3.8 in the 14.04 repo, which I use for cross-checking. I would just like to keep the 14.04 baseline because it makes backports easier. We'll hopefully stay with 5.2 for a while, but I also thought so about a 5.0 release, which was dropped. JMG P.S. 16.04 has gcc 5.3 as default and 5.4 as an update, clang still 3.8. _______________________________________________ LibreOffice mailing list LibreOffice@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice
