We have to specify dedicated output files for these tests, since they rely on which standard library is used, as pointed out in the original commit https://github.com/dealii/dealii/commit/b83b4cf3007d141474d701579cc606ea52addb2b. Thus, we need updates on:\r\n- `tests/hp/dof_renumbering_04.output.clang-libc++`\r\n- `tests/hp/dof_renumbering_05.output.clang-libc++`\r\n\r\nCould someone provide these files, or give assistance on how to build `deal.II` with `clang-7.0` and `libc++-7.0`? I get horrible linker errors when trying the latter in the following configuration...\r\n```\r\ncmake -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_CXX_FLAGS=\"-stdlib=libc++\" -DCMAKE_EXE_LINKER_FLAGS=\"-lc++abi\" -DDEAL_II_WITH_THREADS=OFF ..\r\n```"},"comment":{"url":"https://api.github.com/repos/dealii/dealii/issues/comments/444500780","html_url":"https://github.com/dealii/dealii/issues/7500#issuecomment-444500780","issue_url":"https://api.github.com/repos/dealii/dealii/issues/7500","id":444500780,"node_id":"MDEyOklzc3VlQ29tbWVudDQ0NDUwMDc4MA==","user":{"login":"masterleinad","id":2423533,"node_id":"MDQ6VXNlcjI0MjM1MzM=","avatar_url":"https://avatars0.githubusercontent.com/u/2423533?v=4","gravatar_id":"","url":"https://api.github.com/users/masterleinad","html_url":"https://github.com/masterleinad","followers_url":"https://api.github.com/users/masterleinad/followers","following_url":"https://api.github.com/users/masterleinad/following{/other_user}","gists_url":"https://api.github.com/users/masterleinad/gists{/gist_id}","starred_url":"https://api.github.com/users/masterleinad/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/masterleinad/subscriptions","organizations_url":"https://api.github.com/users/masterleinad/orgs","repos_url":"https://api.github.com/users/masterleinad/repos","events_url":"https://api.github.com/users/masterleinad/events{/privacy}","received_events_url":"https://api.github.com/users/masterleinad/received_events","type":"User","site_admin":false},"created_at":"2018-12-05T14:19:52Z","updated_at":"2018-12-05T14:19:52Z","author_association":"MEMBER","body":"Configuring with\r\n```\r\ncmake -DCMAKE_BUILD_TYPE=Release -DDEAL_II_CXX_FLAGS=-stdlib=libc++ -DDEAL_II_LINKER_FLAGS=\"-stdlib=libc++ -lc++abi\"\r\n```\r\ncompiling works for me.
