Build error: https://github.com/mariocao/actix-p2p #60

Closed PlaneB closed 5 years ago

PlaneB commented 5 years ago

First of all great work! The project is very much appreciated.

Anyway, building https://github.com/mariocao/actix-p2p outside of rust-musl-builder works without error on my Debian GNU/Linux 9 (stretch) 64 Bit machine with cargo 1.30.0 (36d96825d 2018-10-24) . However if I try to build inside the rust-musl-builder, I get the following errors:

E0658:

An unstable feature was used.

Erroneous code example:

#[repr(u128)] // error: use of unstable library feature 'repr128'
enum Foo {
    Bar(u64),
}

If you're using a stable or a beta version of rustc, you won't be able to use any unstable features. In order to do so, please switch to a nightly version of rustc (by using rustup).

If you're using a nightly version of rustc, just add the corresponding feature to be able to use it:

I had the same problem with using it for a project that I moved to the 2018 edition on stable.

Turns out, I had used it earlier, and to update the version of rust in the docker image, you need to pull an update.

docker pull ekidd/rust-musl-builder

After that it worked like a charm.

emk commented 5 years ago

Yup! Please run docker pull ekidd/rust-musl-builder to update your build image. Or you can hard-code a specific Rust release in your Dockerfile:

FROM ekidd/rust-musl-builder:1.31.0

I try to re-build this image once every 6 weeks, generally on the day when a new stable Rust is released, and to tag the individual versions.

If you try this and still encounter this problem, please feel free to re-open this issue, or to file a new one.
