In this project I'm trying to compile a staticlib with musl and install that with a Ruby gem.
./run build will compile the Rust staticlib with musl on debian using
clux/muslrust's docker image.
After compilation it will move the compiled staticlib to an Alpine linux container ruby:2.3.1-alpine and try to install it in a Ruby gem.
./run clean will remove all target directories and caches.
Building the staticlib seems to go fine, but once it's trying to be installed in the Ruby gem the following error is thrown:
$ ruby extconf.rb
