Hi everyone, We have had a discussion about c++11 for at least 2 years. We have decided to allow c++11 features in 2.8, and this implies compiling in c++11 mode with a supporting compiler. This email is not about that.
What i want to propose is to build master ( 2.7x ) in c++11 mode against libraries that are in c++11 ABI ( on platforms that make this distinction. That does not imply allowing c++11 only features or dropping the possibility of being able to compile in c++03 mode. Why would we want to do that ? 1) we are already sort of doing it on windows. MSVC does not really allow you to disable its c++11 support. 2) Modern systems are defaulting to it. this should have nothing to do with us except that it does. We have users trying to use python extensions with blender that we ourselves do not ship. On MacOS the compiler and thus things like homebrew compile against libc++ for some time now people who try to compile extensions need to jump through a lot of hoops in order for things to work. 3) It fits very well with preparing our build-system and libraries for the future / Blender 2.8. We decided to go that way and while i agree we should not make 2.7x depend on c++11 i think building it by default as c++11 does not contradict that decision. 4) We could start to use llvm versions greater then 3.4 for release builds as those need a c++11 compiler I would like to move to msvc2015 for Windows and darwin/libc++/c++11 for MacOS for 2.7x. and 2.8 The only mayor downside i see is that we would effectively drop OS X 10.8 and earlier.
