I’ve been pretty busy in my life recently, but I finally got around writing this blog post. Hopefully, things are sorted out in my personal life and I should be able to be more regular about these updates in the future.
I’m very happy to see good progress towards rustup distribution (thanks to Kobzol again!).


Oh, and
clean alldoesn’t work reliably. Since trying to build inreleasemode after building indebugmode thencleaning is weirdly broken.And It’s not clear from the README how to build in
releasemode without runningtest --release. And the fact that all combinations of--release-sysrootand--release --sysrootand--release --release-sysrootexist doesn’t help 😉Thanks for reporting this! I cannot reproduce with the following:
y prepare y build --release y build y clean all(it shows:
Successfully ran clean all)Could you please provide the commands you ran to get this? (It might also be easier for me to track this if you open an issue on GitHub since I don’t come here often.)
Also, thanks for the suggestion for better documentation: I created an issue for this.
Yeah, apologies for not communicating the issue clearly.
cp config.example.toml config.toml ./y.sh prepare ./y.sh build --sysroot ./y.sh clean all # above commands finish with success # below, building succeeds, but it later fails with "error: failed to load source for dependency `rustc-std-workspace-alloc` ./y.sh test --releaseAnd then trying to use the “release” build fails:

The issue here is that you didn’t provide
--build-sysrootto./y.sh test --release, so it cannot find thestdcrate.But running
./y.sh prepare ./y.sh test --releasedoes work. That’s what gave me the impression that
clean alldoesn’t actually clean everything!It does actually clean everything. You need to call
./y.sh prepareagain if you ranclean all; otherwise, it will fail to find some stuff likerustc-std-workspace-alloc.I opened an issue to improve the documentation in this regards. Thanks for testing all this: this will help me improve the documentation.
Aha! Good to know. And yes, improved documents would be of great help.
Thanks again for working on this.
