emscripten is installed by emsdk install latest.

The way that test works is that it builds the same code twice - once for native, and second time for Emscripten, and then compares the two that they get the same result.

This error message seems to come from the native compilation side. Tried this out on my Linux Mint 18 box, which passes the test, so this seems to be something configuration specific.

Check out this line https://github.com/kripken/emscripten/blob/incoming/tests/test_core.py#L5067, which is running the build. Two things come to mind here:

1. that line is missing -msse compiler directive passed to Clang. I wonder what happens if that is added?

2. If the above does not resolve it: can you search your system to find where the header file xmmintrin.h is located? Perhaps there's an include directive that we are missing that should be added. Note that here the xmmintrin.h from inside Emscripten repository should not be getting used, but the one that is available in the native system compiler.

[saschanaz]

1. No difference.
2. It's in /usr/lib/gcc/x86_64-linux-gnu/5/include, but this seems not clang-compatible as -I /usr/lib/gcc/x86_64-linux-gnu/5/include causes several compile time errors.
