Problem come from your linker with libgomp : ../libs/rawengine/libraw/liblibraw.a(demosaic_packs.cpp.o): multiple common of '.gomp_critical_user_.var' Typically, at linking time, it found 2 symbols from this library. Check your system Gilles Caulier
Thanks Gilles. I was compiling with clang which I think has its own built-in version of libgomp. I switched to compiling with gcc and it works. This bug can be closed.
