Hi there, I learned recently that central parts of KDE Platform 4 are depending on C++11 features:
http://ivan.fomentgroup.org/blog/2012/08/02/module-giveaway-sessions-and- activities-updated/ Using C++11 features in central parts of KDE Platform 4 effectively means that a C++11 compiler is needed for all of KDE Platform 4 (If you start with a non C++11 compiler, you'll only hit the hard requirement later after hours of compiling). So if any part of the KDE Platform 4 requires C++11, we need to have a CMake check in kdelibs ensuring that the required features of C++11 are available. So, that surprised me, because it was not discussed at all here. I tried to find out what code is relevant to what Ivan wrote. It's presumably in 241f48a01d9d33e9d3bb193ac1aace4cf0f19737 "Merged activity-manager-v3 branch", which is not a merge at all, but a single giant patch (therefore making git blame git log and gitk useless in the entire repo from now on. Don't we care about history??? Ivan, please use --rebase when you pull, you're creating a lot of needless merges that don't communicate what a 'merge' usually needs to communicate). So I don't even know which C++11 features are required now by KDE4, whether they are optional (eg guarded by macros), whether there is significant feature degradation without them, etc. Notes: * I didn't state my opinion on whether I think we should have a hard requirement C++11 in KDE4. I'm saying it was never discussed here. * The question/answer for KDE Frameworks 5 is independent * I think it's important to even attempt to discuss things like that with the community before going ahead and just doing it unilaterally. So, lets do it now: C++11 as a hard requirement for KDE Platform/Workspaces/Applications 4. Discuss. Thanks, Steve.
