Hello! The GNU Hurd is now continuously cross-built on Hydra from GNU/Linux:
http://hydra.nixos.org/jobset/gnu/hurd-master There are 3 ‘jobs’ there: - The ‘tarball’ job, which does “make dist”. - The ‘xbuild’ job, which cross-builds off the tarball. - The ‘xbootstrap’ job, which does the full cross-bootstrap procedure (i.e., what the ‘cross-gnu’ script does) using the tarball produced above instead of the Hurd snapshot currently in Nixpkgs. Getting ‘make dist’ to work was surprisingly tedious, presumably because the project has a long tradition of not publishing source releases. ;-) There’s a series of patches at <https://svn.nixos.org/repos/nix/hydra-config/gnu/trunk/hurd/>. Most of them should be obvious. I can provide proper ChangeLog entries so that they can go in (I’ve already assigned copyright), and I’m of course open to discussions. The ‘xbootstrap’ job is the most interesting: it reuses the whole cross toolchain packaging from Nixpkgs and simply overrides the source of the Hurd package. This can be seen from the build steps and run-time dependency graph of a build: http://hydra.nixos.org/build/416968#tabs-buildsteps http://hydra.nixos.org/build/416968/runtime-deps [*] Eventually, it’d be nice to have it override Mach, MIG, and libpthread as well, so we get complete regression testing for the cross toolchain. Similarly, glibcs (sourceware.org and sv.gnu.org repositories) are (about to be) continuously built: http://hydra.nixos.org/jobset/gnu/glibc-master (always fails to build) http://hydra.nixos.org/jobset/gnu/glibc-hurd (‘make dist’ fails) Hydra can send email notifications when the status of a build changes (e.g., from ‘succeeded’ to ‘failed’.) I can add whoever feels like receiving Hydra news. Thanks, Ludo’. [*] If you look carefully, there’s a small glitch: two glibcs, instead of one, are built; one is built with the old Hurd headers and is used only to build ‘hurd-minimal’ (which contains only libihash). I think it can’t hurt, but it’s unpleasant to the eye. ;-)
