Support for Alpine Linux prebuilt binaries

[jcallin]

If anyone is wondering about this and needs a quick fix, I've published prebuilt binaries for v4.4.0 for Alpine Linux here https://github.com/jcallin/headless-gl-alpine-prebuilt/releases and have included steps to including the binaries to be found by gl

I might have opened a PR here, but Travis CI doesn't readily support Alpine Linux build environments in which the binary could be created (correct me if I'm wrong, just gave it half an hour of Googling)

Hi thanks for doing that.

We'd be interested in somehow adding this to this repo in the future.

Are these are the options you passed into prebuild:

node=10.14.2
arch=x64
libc=musl
platform=linux

Perhaps libc=musl can still be built from Ubuntu?

Hm I did it a slightly hackier way. I cloned gl inside an Alpine Docker image and ran npm install. After the bindings were built I cleaned the build and build/Release folders of everything except for the .node file, tar'd build/ and uploaded.

I am not super experienced here, I was doing this for a better CI integration for our front-end project. I didn't want to mess around acquiring musl and passing it to prebuild, so I just let the environment handle it all by building within the docker container.

Another thing I'm thinking is that I may have built the bindings for gl instead of headless-gl. Should I have cloned this repo and done the process I described above instead?

I see that using prebuild is definitely the preferred option and I agree that you could probably just build on Ubuntu and pass the musl libc to it.

Note: This repo (headless-gl) is found on npm as gl, I believe.

That hacky way is how a lot of prebuilds were done a couple of months ago when our CI environment was busted. Since then, linux and osx releases have

Perhaps on the next release, I'll try to remember to update the prebuild script to also build for musl. Hopefully it's as simple as that.
