The problem is in apt-build, as it seems to be wrapping the toolchain binaries and either appending or replacing specific values (like “-mtune”). This occurs as bzip2 is using the toolchain multilib support to build amd64 executables on i386, and then fails as it gets passed “-mtune=pentium-m” which conflicts with the requested “-march” argument. Thus the reassignment. A solution would for apt-build to not replace/append the “-mtune” arguments (and possibly other arch bound ones) when multilib is in use, so it would come down to checking if the -m(32|64) argument is passed and it does not match the current host architecture bits. Newer dpkg-architecture provides a DEB_HOST_ARCH_BITS variable, that could be used for that. > It is likely that this problem also occoured on oether packages. Possibly all multilib enabled packages. regards, guillem -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
