Source: libimagequant Version: 2.12.2-1.1 Tags: patch User: debian-cr...@lists.debian.org Usertags: ftcbfs
libimagequant fails to cross build from source. It has a hand-written configure script that fails to understand the --host flag passed by dh_auto_configure. Instead, one is supposed to pass a CC assignment. That mostly fixes the build, except when building from a !x86 to an x86 architecture: There SSE is supposed to be detected from uname, so the build becomes unreproducible. Instead, a --enable-sse or --disable-sse flag should always be passed. Please consider applying the attached patch. Helmut
