I would get a trunk code. C ++ support has improved significantly since 2.6.
The make file clag-tools / clang / tools / driver uses the CLANG_IS_PRODUCTION command to control whether C ++ is turned on or off. CLANG_IS_PRODUCTION means C ++ is off. By default, there is no CLANG_IS_PRODUCTION for the trunk assembly (i.e. development assembly).
