[cfe-dev] libclang cannot find its resource dir on linux?

[Erik Verbruggen]

Hi,

I have a small test program that behaves differently on linux and mac:

     CXIndex idx = clang_createIndex(1, 1);
    struct CXUnsavedFile unsaved[1];
    unsaved[0].Filename = "tst.c";
    unsaved[0].Contents = "#include <xmmintrin.h>\n";
    unsaved[0].Length = strlen(unsaved[0].Contents);
    CXTranslationUnit tu = clang_parseTranslationUnit(idx, "tst.c", 0, 0, unsaved, 1, 0);

On macos, the translation unit is fine: when running clang_getInclusions on it, I get the full path of xmmintrin.h. However, on linux this fails with "tst.c:1:10: fatal error: 'xmmintrin.h' file not found". Running it on the command-line works fine though. 

So, is this expected behaviour, or a bug?
