Vagga compiled from source using RUST docker image ( https://github.com/tailhook/vagga/blob/master/docs/installation.rst#building-from-source-using-docker )

I added option key --target=x86_64-unknown-linux-mus as recommended here: #6 (comment)

so, commandline is:

docker run --rm --user "$(id -u)":"$(id -g)" -e VAGGA_VERSION=v0.8.1-24-g1afd5a0 -v "$PWD":/usr/src/vagga -w /usr/src/vagga rust cargo build --release --target=x86_64-unknown-linux-musl

Result:

As recommended, I run:

→ docker run --rm --user "$(id -u)":"$(id -g)" -e VAGGA_VERSION=v0.8.1-24-g1afd5a0 -v "$PWD":/usr/src/vagga -w /usr/src/vagga rust rustc --explain E0463
A plugin/crate was declared but cannot be found. Erroneous code example:


> #![feature(plugin)]
> #![plugin(cookie_monster)] // error: can't find crate for `cookie_monster`
> extern crate cake_is_a_lie; // error: can't find crate for `cake_is_a_lie`


You need to link your code to the relevant crate in order to be able to use it
(through Cargo or the `-L` option of rustc example). Plugins are crates as
well, and you link to them the same way.
