Source: traverso Version: 0.49.5-3 Tags: patch User: debian-cr...@lists.debian.org Usertags: ftcbfs
traverso fails to cross build from source from amd64 to non-amd64, because it tries to detect compiler flags from the current cpu. That makes it pass e.g. -msse to an arm compiler. The attached patch disables the detection and adds back some flags for amd64 explicitly. Doing so also fixes #916286. It also improves reproducibility of the package. Further flags can be added to debian/rules by checking DEB_HOST_* variables without compromising base lines or reproducibility as needed. Please consider using or extending the attached patch. Helmut
