I think the docker file may need PATH=$PATH:/.redoxer/toolchain/bin:/rust/bin-> PATH=$PATH:/root/.redoxer/x86_64-unknown-redox/toolchain/bin

No idea then, perhaps @jackpot51 knows.

(On that note, maybe you'd like to add a second target maintainer for redox? Just so you're not the only one to get pinged)

xtqqczze · 2026-08-04T15:01:21Z

For uutils, we ended up switching CI for the Redox target to check-only: uutils/coreutils#10950.

I wonder if a similar approach would make sense for some of the libc targets as well.

tgross35 · 2026-08-04T17:02:55Z

We do ensure it builds at least,

libc/ci/verify-build.py

Line 154 in cc74750

Target("x86_64-unknown-redox"),

. Tests would just be nice if we could get them to work.

Alternatively if Redox happens to be mirroring libc and testing it in their repos somehow, we could just link it at #5209.

 RUN mv /root/.redoxer /.redoxer

-ENV PATH=$PATH:/.redoxer/toolchain/bin:/rust/bin \
+ENV PATH=$PATH:/root/.redoxer/x86_64-unknown-redox/toolchain/bin \


From the CI manual, it should be more reliable to do this

Suggested change

ENV PATH=$PATH:/root/.redoxer/x86_64-unknown-redox/toolchain/bin \

RUN ln -sf /root/.redoxer ~/.redoxer

ENV PATH=$PATH:$HOME/.redoxer/x86_64-unknown-redox/toolchain/bin \

I have no idea where EPERM could happen, I haven't fully tested run-docker.sh, at glance it looks like it should works (the requirement to get the toolchain to work is only glibc >= 2.41), but let me know if this suggestion still fail so I can test myself.

I'm the build maintainer for Redox OS, so feel free to ping me anywhere about CI for redox.

Right, we at least get build errors now.

Looks like a lot of work to do, can it be optional for now? I can also help in spare time.

There’s no way to make the whole job optional, but you can add a test skip for anything that’s not trivial to fix (see the skip_* functions in the libc-test/build directory)

I think I can send PR to that file separately

Is there a way forward for this PR? I don't have the expertise to resolve build errors so I'm minded to close it.

I can create another PR that start from this, but I don't have the time to do it yet. Feel free to close this one.

Issue opened: #5520. Perhaps this PR can be merged with the progress so far.

I'm happy to take this but please update the commit message, since this doesn't enable it anymore

ah, bad rebase, sorry for the pings
