mitmproxy won't build

Been trying to emerge net-proxy/mitmproxy, but net-proxy/mitmproxy-rs always fails with the "ld: file format not recognized" error, see the log here. Anyone know how I can fix this? I have a bunch of other packages that fail with the same error, so maybe whatever solves this will solve those, too.

You post build.log is for net-proxy/mitmproxy-rs.

You can't use Rust LTO unless you build with Clang.

sam_, I'm not building it with LTO. pingtoo, yes, I'll correct that.

The log has '-C linker-plugin-lto' (and later -C lto) but it might be being forced by the upstream project if you're not doing that.

OK, so should I try forcing clang to be the C compiler, just for this build?

Yes, please give it a go. But please file a bug at bugs.gentoo.org with the build.log and emerge --info.

I tried forcing clang, and there was a slightly different error message: "lto can only be run for executables, cdylibs and static library outputs". Pretty sure it's an upstream problem.
