Working rust setup is currently hacked around on x32 builder which consists of both rust.x32 and rust.x86_64 installed side by side. Few remarks/thoughts: - rust 1.47 on x32 built x86_64 compiler with target support for both x86_64 and x32 (two directories under /usr/lib/rustlib) - rust 1.48 and higher appears to build x86_64 compiler with single target support: x32 - since parts of build process require building things for host (which is x86_64) it started to fail with "can't find crate for `std`" due to missing target for x86_64 - that's why installation of rust.x86_64 next to rust.x32 helped -- it provides x86_64 target support - I haven't noticed that x32 patch was left commented out so I guess it's not required anymore? As for solution not sure which one is least bad: 1. Just R: rust(x86-64) in rust(x86-x32) 2. Package just target support files and R: rust(x86-64) for the rest 3. Package target independently ie rust-target-x86_64 and require it in rust(x86-x32) 4. Other Happy to pass over decision and implementation to somebody else :). _______________________________________________ pld-devel-en mailing list pld-devel-en@lists.pld-linux.org http://lists.pld-linux.org/mailman/listinfo/pld-devel-en
