I am puzzled as to why SuiteSparse_GraphBLAS drags in clang17 and
SuiteSparse_LAGraph drags in both clang16 and clang17 as build
dependencies. I don't see anything in the SuiteSparse Portfile showing
those dependencies.
LLVM 17 is a few versions back, LLVM 18 and 19 are both available, so it
could be its just too old for macOS15. Can you please try forcing any
build that is falling back to using clang-17 to use clang-18 and/or
clang-19 instead ? you can do that by appending
configure.compiler=macports-clang-18
to your port install command, e.g.
> sudo port install foo configure.compiler=macports-clang-18
If that works we should then veto adding 17 (or older) as fallbacks on
macOS15, at least until someone has time to investigate the problems there.
