I tried to compile a C++11 program with clang-cl under Windows. Clang-cl is the wrapper around clang to be more compatible with cl (Visual Studio compiler). I tried to add -std=c++11 and /std=c++11 and both get rejected. This is to no surprise as cl has no C++11 flag.
But I can not use C++11 features with clang-cl.
How can I enable C++11 support in clang-cl?
In the documentation mentioned before says: http://clang.llvm.org/docs/UsersManual.html#clang-cl
clang defaults to C++11 for Windows targets.
Maybe you don't need to pass any flag to clang-cl.
From official docs:
/std:<standard>
