Reintroduce using system v8 (for Alpine Linux support)

[volkanunsal]

I'm trying to install libv8 on Alpine. As has been noted here, libv8 build doesn't support Alpine's muslc library. So I thought I could use the system library with --with-system-v8, but saw that it had been removed in an earlier version. Is there an alternative? What is the best way to install libv8 on Alpine?

We're interested in this as well. You could install the libv8 package via apk and get things into system ruby, but we're doing things via bundler, Gemfiles, and Gemfile.lock so this really isn't viable.

Hello,

Could you point me to a packaged V8 for Alpine? I would like to see how they managed to build the package and explore ways to use it.

I have been thinking about reintroducing linking against a shared library for of V8, however I want to do it correctly this time by verifying version compatibility as well.

Is there any update on this? It has become a huge problem for us...

[ignisf]

@ciroque are you having issues with Alpine as well?

Hi, we support Alpine in a product that rely on V8, so we built and made available the libv8 version we use here. I think the repo we use to build V8 is here but it might be outdated.

so how do we get bundler to see libv8-alpine as libv8?

bundle complains libv8 is not installed...

EDIT: burned it down and built Debian-stretch-mini ruby dev container instead. (guess I won't be using alpine in prod for ruby apps then)

[Taiki-San]

They're different packages, a the Gemfile need to detect when it's running on Alpine and gem libv8-alpine instead of libv8. The requesting gem also need to aware of the changes in names.
The fix would be to integrate those in the main libv8 package, but I don't know how it's done in other Ruby gems.

This would be useful for us in Nixpkgs as well.

Made a comment here regarding musl support and a possible partially upstream solution: #270 (comment)

[lloeki]

libv8-node has Alpine support now.

Closing as musl is supported by libv8-node.
