build fails with musl target

[opensourcegeek]

When I run cargo build --target i686-unknown-linux-musl I get the following error

error[E0463]: can't find crate for proc_macro
--> /home/opensourcegeek/.cargo/registry/src/github.com-1ecc6299db9ec823/proc-macro-hack-0.3.3/src/lib.rs:159:1

159 | extern crate proc_macro;
| ^^^^^^^^^^^^^^^^^^^^^^^^ can't find crate

Seems like proc-macro-hack depends on proc_macro crate - I cannot find it in crates.io, there is only proc-macro2. I'm not sure how the build works fine on gnu target, I'll dig more but thought I'll report here as well.

Which version of rustc are you running? We currently test on v1.17.0 and above but the proc_macro crate should be available from v1.15.0 IIRC.

Edit: We don't test against the musl target though...

@opensourcegeek According to dtolnay/proc-macro-hack#6 (comment) we need to disable default-features for proc-macro-hack to fix this.

@rushmorem Thanks - I've forked the project and disabled default features and it seems to work.

Thanks for the feedback. I'm reopening since the fix hasn't been applied to this repo yet. Mind submitting a pull request with your changes?

Now fixed in version 0.0.10.
