Source: dialign-t Version: 1.0.2-9 Tags: patch User: helm...@debian.org Usertags: rebootstrap
dialign-t fails to cross build from source, because it determines compiler flags from the build architecture rather than the host architecture. Thus cross building for e.g. mips can include -mmmx. The attached patch goes a little further than s/BUILD/HOST/. It removes the need to invoke the shell for each make invocation by relying on dpkg's architecture.mk. It also enables -mmmx for more architectures that may be relevant by matching on the cpu. It will enable these flags on e.g.: * x32 * kfreebsd-amd64 * hurd-i386 * musl-linux-i386 Please consider applying it. Helmut
