Package: rustc Version: 1.10.0+dfsg1-2 Severity: normal Dear Maintainer,
armhf currently fails to build on buildds but does build successfully on porterbox harris.debian.org This is because rust upstream assumes arm-unknown-linux-gnueabi has neon: src/librustc_back/target/armv7_unknown_linux_gnueabihf.rs: features: "+v7,+vfp3,+neon".to_string(), whereas Debian's armhf targets machines without neon, including all current buildds, but only harris has it: infinity0@harris:~$ grep neon /proc/cpuinfo Features : swp half thumb fastmult vfp edsp thumbee neon vfpv3 tls vfpd32 The build fails running the upstream stage0 compiler because that contains neon instructions. To fix this we'll have to 1) patch rustc to not use neon, and 2) do a binary-only upload for armhf, either by a) building on harris, but this takes 2-3 days b) finding a faster armhf machine with neon to build it on, or b) cross-compiling from another architecture X -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (990, 'testing'), (500, 'stable'), (300, 'unstable'), (200, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.6.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_GB.utf8, LC_CTYPE=en_GB.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages rustc depends on: ii gcc 4:5.3.1-3 ii libc6 2.23-4 ii libc6-dev [libc-dev] 2.23-4 ii libjs-jquery 1.12.4-1 ii libstd-rust-dev 1.12.0~~nightly.20160805+dfsg1-1 Versions of packages rustc recommends: ii rust-gdb 1.10.0+dfsg1-1 Versions of packages rustc suggests: ii rust-doc 1.10.0+dfsg1-1 -- no debconf information
