cargo install wasm-bindgen-cli fails on windows (travis)

[najamelan]

Describe the Bug

It fails to compile with linker errors seemingly related to libcurl. Happens on both stable and nightly. I runs fine in linux and mac os.

Steps to Reproduce

1. Go to https://travis-ci.org/najamelan/async_executors/jobs/652183842
2. The travis.yml: https://travis-ci.org/najamelan/async_executors/jobs/652183842/config

I haven't found time to debug this further, but I thought I'd report it because others might start to see builds failing.

Last part of the log:

Thanks for the report! This is a build issue however with one of the dependencies, specifically curl-sys. The fix here should be in nightly Rust at this point and otherwise I'd recommend using the MSVC toolchain wherever possible. I don't think is a wasm-bindgen issue, however, so I'm going to close this.

[najamelan]

Thanks for clarifying, and good that it's already fixed. I suppose it should go away as soon as travis updates the rust nightly. I'll keep an eye out to see if it solves itself. The issue was detected on:

rustc 1.43.0-nightly (0176a9eef 2020-02-17)
$ rustup --version
rustup 1.21.1 (7832b2ebe 2019-12-20)
$ cargo --version
cargo 1.43.0-nightly (3c53211c3 2020-02-07)

Still seeing this on:

$ rustc --version
rustc 1.43.0-nightly (6d0e58bff 2020-02-23)
$ rustup --version
rustup 1.21.1 (7832b2ebe 2019-12-20)
$ cargo --version
cargo 1.43.0-nightly (e57bd0299 2020-02-21)

I doubt the problem was solved in rust-lang/rust#67429.

Ah ok, sorry you're still seeing this! In any case it's an issue for the curl crate or upstream rust-lang/rust rather than this crate.
