Hi, Danny Milosavljevic skribis: > Do we support lib32 a la "gcc -m32" ? How can we provide a working glibc for that? It seems that rustc bootstrap is trying to use that option. We don’t support multilib, so glibc provides only 64-bit headers on x86_64 (if you try -m32 there you’ll get an error about missing or something like that.) Ludo’.
