Most of these are the same RFC 1214 errors we’ve already seen. Here’s the new stuff:

• codegenta, eligos, genetic - RFC 1214
• servo-skia - weird custom build error

Since some important crates haven’t been updated for RFC 1214 seems we should submit PRs.

servo-skia - weird custom build error

I can't reproduce this on beta locally. Looking at the error I suspect it may be a race condition in our makefile, unrelated to any changes in Rust/Cargo.

@mbrubeck how’d you reproduce it? just running cargo build with beta?

how'd you reproduce it? just running cargo build with beta?

Yes. I used multirust to install rustc 1.7.0-beta.2 (f4b756e6c 2016-02-03) and ran cargo build. I tried a few times with different -j options (trying to test my race condition theory) but the build succeeded every time for me.

Oh sorry! I misread “can’t reproduce this” as “can reproduce this”, my bad! Carry on…
