Well yes, there will be conflicts. Those conflicts are entirely independent of the M-A value though. You see gcc-i686-linux-gnu:amd64 will contain /usr/bin/i686-linux-gnu-gcc. gcc:i686 presently contains the same file. You cannot coinstall gcc-i686-linux-gnu:amd64 and gcc:i386 in any case. > And how about if multi foreign architecutures are added, for example: > i686> dpkg --add-architecutre amd64 arm64 ppc64el > ? Well, you install only one compiler targeting i386. You get to choose from which of these architectures you want to install the compiler. You can only install one package owning /usr/bin/i686-linux-gnu-gcc at a time. This seems pretty normal to me. What's the issue? Helmut
