Hello Guix! I noticed the recent rust changes on core-updates, so I was eager to try and get rust working on aarch64 again, but I noticed I couldn't bootstrap because the pthread tests from findutils-boot0 were failing. I was just about to send a patch for that and then saw we had disabled the tests all together. So, here's an updated patch that re-enables them again, but disable only pthread tests. Let me know what you think of this patch, I've tested it on aarch64 and currently building rust 1.29, but I wasn't able to test it on x86, I'm getting the following failure: --8<---------------cut here---------------start------------->8--- starting phase `compress-documentation' compressing documentation in '/gnu/store/fl4xmk5pln6lw81ixjk3w24hhdn1zi26-findutils-boot0-4.8.0/share/man' with "gzip" and flags ("--best" "--no-name") sterror: unknown error: /gnu/store/fl4xmk5pln6lw81ixjk3w24hhdn1zi26-findutils-boot0-4.8.0/share/man/man1/find.1 sterror: unknown error: /gnu/store/fl4xmk5pln6lw81ixjk3w24hhdn1zi26-findutils-boot0-4.8.0/share/man/man1/locate.1 sterror: unknown error: /gnu/store/fl4xmk5pln6lw81ixjk3w24hhdn1zi26-findutils-boot0-4.8.0/share/man/man1/updatedb.1 sterror: unknown error: /gnu/store/fl4xmk5pln6lw81ixjk3w24hhdn1zi26-findutils-boot0-4.8.0/share/man/man1/xargs.1 sterror: unknown error: /gnu/store/fl4xmk5pln6lw81ixjk3w24hhdn1zi26-findutils-boot0-4.8.0/share/man/man5/locatedb.5 error: in phase 'compress-documentation': uncaught exception: srfi-34 # phase `compress-documentation' failed after 0.0 seconds command "gzip" "--best" "--no-name" "/gnu/store/fl4xmk5pln6lw81ixjk3w24hhdn1zi26-findutils-boot0-4.8.0/share/man/man1/find.1" "/gnu/store/fl4xmk5pln6lw81ixjk3w24hhdn1zi26-findutils-boot0-4.8.0/share/man/man1/locate.1" "/gnu/store/fl4xmk5pln6lw81ixjk3w24hhdn1zi26-findutils-boot0-4.8.0/share/man/man1/updatedb.1" "/gnu/store/fl4xmk5pln6lw81ixjk3w24hhdn1zi26-findutils-boot0-4.8.0/share/man/man1/xargs.1" "/gnu/store/fl4xmk5pln6lw81ixjk3w24hhdn1zi26-findutils-boot0-4.8.0/share/man/man5/locatedb.5" failed with status 1 builder for `/gnu/store/g64zjdljpk4wawimf44v7ysgf23ywg30-findutils-boot0-4.8.0.drv' failed with exit code 1 build of /gnu/store/g64zjdljpk4wawimf44v7ysgf23ywg30-findutils-boot0-4.8.0.drv failed View build log at '/var/log/guix/drvs/g6/4zjdljpk4wawimf44v7ysgf23ywg30-findutils-boot0-4.8.0.drv.bz2'. --8<---------------cut here---------------end--------------->8--- I'm a bit confused what's going on, anybody has a clue? By the way, I'm glad we no longer have to pass all the tests for every stage of the rust bootstrap, getting this working on different platform was quite tedious :-). Thanks, Pierre
