For another thing, libmesh doesn't actually use the LIBMESH_HAVE_CXX11_TYPE_TRAITS for anything, so it would only matter if you are somehow using this #ifdef in your app. That said, I use clang 3.9.0 and it passes this test, so I'm not sure what might be different with your clang 4.0.0 install. Also, it looks like you are somehow passing -std=c++14 to the configure test (manually setting libmesh_CXXFLAGS?) which I haven't tested myself, but should not make any difference to this particular test. -- John ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
