Elm 0.19.0 Linux x64 statically linked binary

This document describes how to build a statically linked binary of Elm 0.19.0 for Linux x64 using docker. The binary is built using Alpine Linux in order to easily link it statically to musl libc. This is how the official Elm 0.19.0 Linux binary was built.

Why?

Why build a statically linked binary?

Elm is currently distributed using npm. For Linux x64 (but this applies to any architecture), this requires to have a single x64 binary that works on all Linux x64 distributions. This is considerably easier to achieve by building a statically linked binary that will only depend on the Linux kernel ABI and System Call Interface but not on userpace libraries (see here for a compatibility survey of a dynamically built executable).

Why use docker?

You'll need to include two pollyfils before you include a code with your custom elements:

• webcomponents/webcomponentsjs/custom-elements-es5-adapter.js - this is for new browsers in order to understand ES5 syntax

• webcomponents/custom-elements/custom-elements.min.js - this is for old browsers without customElements support

You can add them to your index.html file in the following way:

<div id="custom-elements-adapter">
