On Ubuntu 18.04 make vagga fails with error `x86_64-unknown-linux-musl` target may not be installed`

[bieli]

I need vagga app. on my Ubutu 18.04 desktop (DELL Intel machine): $ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu Bionic Beaver (development branch) Release: 18.04 Codename: bionic

$ uname -a Linux machinename 4.15.0-13-generic #14-Ubuntu SMP Sat Mar 17 13:44:27 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

After I checkout vagga source code and try cmd: "make vagga" I got error like this:

   Compiling quick-error v1.2.1
error[E0463]: can't find crate for `core`

  = note: the `x86_64-unknown-linux-musl` target may not be installed`

It's possible to make, when I change Makefile like this:

Hi,

If you don't want to build vagga by vagga : vagga make, you need to install musl stdlib. From the top of my head it's:

rustup target add x86_64-unknown-linux-musl

You may also need installing musl-tools and these packages setting some environment like this

[tailhook]

building it with gnu libc makes vagga unrunnable because glibc needs some shared libraries, and vagga often runs itself in a container where shared libraries from your host system aren't available.

Doesn't look like anything actionable left here.
