WIP - Add x86_64-musl as a host architecture #57359

martell · 2019-01-05T21:06:14Z

ignore this I am just looking at #55163 and trying to trigger the build bot

The musl-target doesn't automatically disable static linking of musl when building a dylib, and then complains it can't build a dylib. As a workaround, disable static linking via RUSTFLAGS, to see how far the build gets. The proper fix is to have rustc figure that out automagically.

…arget binaries

This reverts commit e52ea15.

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @nikomatsakis (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see the contribution instructions for more information.
