I think there might be something wrong with your installation. clang++ -std=c++0x hello.cpp clang++ -std=c++11 hello.cpp Both works fine here and creates an exe a.out Which version of clang/llvm are you using?

C K Kashyap <ckkashyap at gmail.com> writes:> I'd really appreciate some pointers in this regard.Possibly gcc 4.6 libstdc++ is incompatible with Clang's C++11 mode. I remember having problems with Clang, C++11 and libstdc++ until some Kubuntu release "fixed" them.
