Hi, I'm using macports version 2.11.5 on macos 10.15.7 catalina.
I'm trying to install atlas via the command sudo port install atlas +gcc15 I have gcc15 installed and selected. I have clang-5.0 installed and selected. When i try to install atlas, i get this message: clang-3.7 is known to fail. Try to install anyway? [y/N] Sure enough, it does fail. But i don't want to use clang-3.7, i want to use clang-5.0. This is not because i expect anything better from clang-5.0, but just so i can try to get past the failure: if clang-5.0 fails, then i would try other versions of clang. 'port select clang' lists 6 versions i can try. And clang-3.7 is not even listed among the possibilities. So . . . how can i get gcc15 to use something besides clang 3.7? TIA for any answers or suggestions or other info. dan
