Package: mini-soong Version: 0.20201028 Tags: patch User: [email protected] Usertags: ftcbfs cross-satisfiability Control: affects -1 + src:libldac
libldac cannot be cross built from source, because its mini-soong dependency is not satisfiable. In general, Arch:all packages can never satisfy cross Build-Depends unless marked Multi-Arch: foreign or annotated :native. Most build systems tend to be annotated Multi-Arch: foreign so I suggest doing it here as well. However, it defaults to the build architecture compiler. While mini-soong consumes DEB_HOST_* variables for a lot of things, it does not yet seed the compiler from them. Doing so is relatively easy using dpkg's buildtools.mk as buildflags.mk already is being used. I'm attaching a combined patch and once it is applied, libldac actually cross builds. What do you think about it? Helmut
