Any ideas on how to fix that ?</blockquote>

<div>Any particular invocation of Clang should only find the
built-in headers corresponding to that binary; it should
look in $(dirname $argv0)/../lib/clang/3.4/include for
those. Can you run the build command with -v and try to
figure out why the include path contains both
/usr/include/clang/3.4/include and
.../bin/../lib/clang/3.4/include? (Which of these
corresponds to the clang binary being used, and why is the
other one on the include path?)</div>
</div>
</div>

The Debian clang package is patched to search also in
/usr/include/clang/3.4/include<br>
<br>
Anyway, module.map should not included twice. <br>
