I’m building llvm-project from a historical version and trying to build mlir upon it.
I’m trying to use clang+±15 during building, but got error saying lack of libcxx. I assumed it would be needing libcxx15 although I was not sure. But when I started to build mlir after llvm is built, it kept giving errors during linking, so suspecting something to do with libcxx I installed.
So would anyone give advice how should I confirm which version of libcxx that I would be needing?
