1320269 - Can't build unicode-bidi Rust crate on GNU/Linux ARMv7hf

Status: RESOLVED WORKSFORME

(Firefox Build System :: General, defect)

Description

[Henri Sivonen (:hsivonen)]

Steps to reproduce:
 1) Obtain an ARMv7 hard float system with 2 GB of RAM. (I used Debian Jessie on the virt device of qemu-system-arm.)
 2) Install Rust from rustup.rs. (For me, rustc --version says "rustc 1.13.0 (2c6933acc 2016-11-07)".)
 3) Apply the workaround from bug 1320022 comment 2.
 4) --enable-rust in mozconfig (I also enabled optimize and disabled debug.)
 5) ./mach build

Actual results:

You may want to try 1.14 beta. Rust 1.13 is broken for ARM targets. See https://blog.rust-lang.org/2016/11/10/Rust-1.13.html

Good point. Thanks.
cd third_party/rust/unicode-bidi/; cargo build
compiles seemingly successfully with 1.13, but I'll try Rust 1.14.

All the Rust crates in the tree build with Rust 1.14.
