I already explained how to workaround the issues you saw. The compilers do
work in most normal situations, i use them extensively, even for linking to
rust software (macOS and Linux), the only caveat being that you should
instead so conda cdt packages on Linux for system library dependencies and
on macOS you need to get an old SDK.
