Redox CI

[jackpot51]

This does the following:

• Fix compilation on Redox
• Add Redox (x86_64-unknown-redox) to the tier2 CI targets
• Bump version to 0.2.59, so that the broken version 0.2.58 is superseded

Redox CI should be tested before merging, I know it compiles for Redox locally but I do not know if it will work on Travis.

This may require rust-lang/rust#60547

[gnzlbg]

There appear to still be lots of errors even when using ctest 0.2.14. Do the tests pass for you locally?

[gnzlbg]

If the tests don't pass, you might want to add this CI job to the allowed_failures list for the moment, and once things are fixed upstream, try to get the test passing here.

[gnzlbg]

Triggering a new CI-build. This still had lots of CI errors last time. Would you mind fixing those?

[mati865]

I think it's blocked on rust-lang/rust#60547

☔ The latest upstream changes (presumably c8aa8ec) made this pull request unmergeable. Please resolve the merge conflicts.

[newpavlov]

Can you also add this fix?

[mati865]

It won't be necessary after rust-lang/rust#60547

[newpavlov]

Right now libc is completely unusable on Redox target. And we don't know how long it will take for the rust-lang PR to get merged, while this PR can be merged relatively soon after the CI issues get fixed. Plus, even with the merged PRs, you will still have this bug on current and previous stable releases.

[gnzlbg]

This needs rebasing.

[gnzlbg]

@jackpot51 any chance of getting back to this soon ? It would be great if you could run libc-test on redox, and update this to be "ABI compliant".

[jackpot51]

Yes, I am very interested in that too. I'm just busy with trying to get rustc running on Redox

I'm going to close this as inactive, feel free to re-open it or submit another PR when you find some time to work on (I've made some progress on #1934 so rebooting should be simple).
