Build log

It has been fixed on Firefox ESR, but Spidermonkey 78.6.0 fails with rust 1.48.

There is a patch in Firefox ESR to change the dependencies from packed_simd to v0.3.4, but Spidermonkey also uses packed_simd v0.3.3 in `third_party/rust/rand/`.

Comment 1 Anthony Ruhier 2020-12-28 13:28:33 UTC

I tested with rust 1.47, and same thing.

I cannot reproduce, spidermonkeys-78.6.0 builds without any problems for me against rust-1.48.

Keep in mind we apply same patch set we apply to firefox:78esr and your build log shows '38-bmo-1667736-Update-packed_simd-to-compile-on-Rust-1..patch ...'.

Comment 3 Anthony Ruhier 2020-12-29 00:06:06 UTC

It's really weird, but it's due to a rustflag I set: `RUSTFLAGS="-Ctarget-cpu=native"`. Unset it for spidermonkey fixes the issue.

I'm closing the bug, sorry for the wrong report.
