I am trying to compile it with the following command on OSX but I wasn't able to get it working:

  clang  -std=c++11  -g -O0 -fno-builtin -arch x86_64   -fno-limit-debug-info -I$LLVM_ROOT/lldb/packages/Python/lldbsuite/test/make/../../../../../include -include $LLVM_ROOT/lldb/packages/Python/lldbsuite/test/make/test_common.h  -stdlib=libstdc++ -DLLDB_USING_LIBSTDCPP --driver-mode=g++ -c -o main.o main.cpp

Compile error (first few):

  main.cpp:12:8: error: no member named 'unique_ptr' in namespace 'std'
    std::unique_ptr<char> nup;
    ~~~~~^
  main.cpp:12:23: error: expected '(' for function-style cast or type construction
    std::unique_ptr<char> nup;
                    ~~~~^
  main.cpp:12:25: error: use of undeclared identifier 'nup'; did you mean 'dup'?
    std::unique_ptr<char> nup;
                          ^~~
                          dup

  int      dup(int);
           ^
  main.cpp:13:8: error: no member named 'unique_ptr' in namespace 'std'
    std::unique_ptr<int> iup(new int{123});
    ~~~~~^

    std::unique_ptr<int> iup(new int{123});
                    ~~~^
  main.cpp:13:24: error: use of undeclared identifier 'iup'; did you mean 'dup'?
    std::unique_ptr<int> iup(new int{123});
                         ^~~
                         dup

  int      dup(int);

I think the problem is that this is testing libstdc++ what is not available on OSX.
