I was trying to cross compile 32-bit Mesa in 64-bit Debian testing some time ago, and while it used to work well in the past using i386 llvm and clang dependencies with gcc-multilib and related tools, at some point it stopped working because of packaging changes.

Namely, libclang-8-dev:i386 became non co-installable with gcc-multilib g++-multilib. It boils down to libc6-i386 conflicting with libc6-amd64:i386.

Debian developers said, they can't do anything about that change, and recommended for example splitting llvm/clang packages into regular and multilib variants.

See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=890801 for details.

Can you please make such kind of split for packages in apt.llvm.org to enable cross compilation?

Is it something for this bug tracker, or rather belongs in the Debian one?

Quuxplusone commented 5 years ago

Yeah, should be on the debian side
