This is, I'm afraid, out of the test runners hands. The issue is that clang (the same binary) works fine on these platforms if we disable c++11, not sure why enabling c++11 triggers missing cstddef header problems.
That's because you use libstdc++ in a C++03 mode and libc++ (-stdlib=libc++) in a C++11 mode.
1. What's your system? Mac OS X 10.6?
Same failure pattern on both Darwin and Linux. Yes Darwin is: System Version: Mac OS X Server 10.6.8 (10K549)
2. Did you install libc++? If not, please install it. See the instruction "Get it and get involved!" at http://libcxx.llvm.org/ .
Sorry, missed this crucial step.
3. If you already installed libc++ but the error happens, then your libc++ is not installed to the standard location. Could you check which directories are searched by clang (by compiling with "-v" option) and where your libc++ headers are installed? If you don't want to install libc++ to the standard location, you can pass -IPATH_TO_YOUR_LIBCXX_INCLUDE_DIR and -LPATH_TO_YOUR_LIBCXX_LIB_DIR as clang's command line options to specify the location of your libc++.
The instructions suggest this: To build on Mac OS X 10.6 (Snow Leopard), you need a helper library and header found here. cp cxxabi.h to /usr/include, and cp libc++abi.dylib to /usr/lib. But I'm not a sysadmin so I can't write into those locations. Do you know if clang will work correctly if those files are located elsewhere?
P.S. -stdlib=libc++ should be added to <linkflags>, too.
Ah yes, I probably forgot to add this, thanks for pointing that out. Thank you very much for the detailed instructions, links, etc.. that really helps me out. -- Noel
