2018-10-31gitlab-ci: arm64 cross compilingDaniel Vetter
First I tried to build in a full sysroot, but I didn't figure out why ld never found the libraries (this was on fedora, which might have been part of the problem - if you just need a toolchain for kernel corss-building fedora is perfectly fine). Then I tried using debian's multiarch stuff, which worked a lot better, except there's some minor gotchas: - some libraries conflict and can't be multi-arch installed - some libraries are buggy and cause conflicts when installing - pkgconfig and ld get confused with some other libraries and pick the first one they find (i.e. the x86_64 one, not the arm64 one). That means we need a new docker image with just the cross libaries installed as -dev packages, and none of the native ones. Next up I tried to run the tests. Meson has really nice support for an exe wrapper, and qemu happily runs arm64 on x86_64. With that I managed to run some tests successfully (it's not even that slow!). But most are run through a script, and the script doesn't know about the exe wrapper and hence fails miserably. I discussed this a bit with Dylan and he filed an upstream meson issue: https://github.com/mesonbuild/meson/issues/4427#issuecomment-433553689 Another option would be to use binfmt-misc handling (which works neatly locally), but on the runners we have I can't control that. Maybe I can beg Daniel Stone ... For not let's just mark this stage as optional and that failures are allowed. v2: Use the new gitlab 1.4 feature to rebuild docker images when necessary.
