Source: gcc-7 Tags: patch User: helm...@debian.org Usertags: rebootstrap Hi Matthias,
there is yet another issue with the current cross compiler build (using -$arch-cross packages, not the with_deps_on_target_arch patchset). In the unstaged cross compiler build, unannotated dependencies on the multilib libc packages are emitted. See this installation failure for instance: | Setting up gcc-7-cross-base (7.1.0-5) ... | Setting up gcc-7-mips-linux-gnu-base:amd64 (7.1.0-5) ... | dpkg: dependency problems prevent configuration of lib64atomic1-mips-cross: | lib64atomic1-mips-cross depends on libc6-mips64 (>= 2.24); however: | Package libc6-mips64 is not installed. | | dpkg: error processing package lib64atomic1-mips-cross (--install): | dependency problems - leaving unconfigured | dpkg: dependency problems prevent configuration of lib64gcc-7-dev-mips-cross: | lib64gcc-7-dev-mips-cross depends on lib64atomic1-mips-cross (>= 7.1.0-5); however: | Package lib64atomic1-mips-cross is not configured yet. Here, we can see that lib64atomic1-mips-cross depends on libc6-mips64. For lib64atomic1, that would be the correct dependency, but for a dpkg-cross'ed package, it should have transformed the dependency to libc6-mips64-mips-cross. The updating should happen in a sed expression transforming the corresponding substvars file in debian/rules.defs. The attached patch fixes the sed expression. In principle, this bug also applies to gcc-6, but I don't think it is worth fixing there. Helmut
