  • Ticket #59584

    • Property Summary changed from macports-clang versions < 5.0 don't understand -stdlib=macports-libstdc++ to macports-clang versions <= 3.7 don't understand -stdlib=macports-libstdc++

  • Ticket #59584 – Description

    initial v2  
    11currently base will try to pass `-stdlib=macports-libstdc++` to clang 3.4 or 3.7 under certain circumstances of blacklisting and whitelisting when the  compiler c or c++ standards are set to >= 2011.

    5 we don't have `macports-clang-3.9` any more, so practically for us macports-clang versions < 5.0 can only be used for compiler.cxx_standard >= 2011 or compiler.c_standard >= 2011 if `configure.cxx_stdlib=libc++`.
     5macports-clang versions <= 3.7 can only be used for compiler.cxx_standard >= 2011 or compiler.c_standard >= 2011 if `configure.cxx_stdlib=libc++`.
