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