Hi,

I'm trying to build packages with flang-21 and flang-22 simultaneously.

(Building with dh-fortran which keeps the libraries/modules separate; the aim is to get modules for
both compilers simultaneously).
flang-21 and flang-22 (etc) can't be co-installed because libmlir-x.y conflict. However it appears they are
distinct and should be able to co-install; is this a relic of previous versions or am I missing
something?

Best regards
Alastair

Will do.

I am currently testing flang-21 and flang-22 co-installation, and
testing a patch.

Multiple llvm-toolchain builds make this a slow process on my test VM :-(

Will reply soon
