Musl LibC Support

[theoparis]

What is the problem this feature will solve?

It will allow bun to be used in linux distributions such as Alpine Linux or BunOS. This could also potentially solve #255.

What is the feature you are proposing to solve the problem?

I have already attempted to implement this by creating a patched dockerfile, build.zig and makefile for building bun under alpine linux. However, it is missing proper FFI support, which seems to be an issue with the internals of bun (as FFI and static linking seems to work with deno).

What alternatives have you considered?

Found this closed issue that suggests JavaScript Core may run on musl https://bugs.webkit.org/show_bug.cgi?id=187485

I'm also using Alpine Linux and being unable to run bun.

Please add a 👍 to the first post instead of adding "me too" comments 🙏

WebKit is shipped on some musl Linux distros, which implies support for JavaScriptCore.

Why was the above comment marked as "off topic"? It is showing a temporary solution to the issue and it would help contribute torwards a permanent fix in the future.

It would be nice if you could send the patches as well.

I need motivation to write a "normal" patch

@Nyaa97 Would it not have been faster to type git diff and paste the result here instead of typing out all the steps?

That aside, do you still have your working code that you could share here?

This issue/feature request is the most upvoted and probably the most viewed by people trying to get Bun works on Alpine but lack an official statement from the core team about the plans around it.

Is the progress on this feature blocked by other issues? Is it complex/time consuming to do? Is it complex to maintain? Is it just low priority? Is it on the 2025 roadmap?

Thanks a lot, can't wait to use Bun on Alpine.

I have updated my patch to musl, but it still needs some tweaking
If anyone is willing to help, I would be grateful
musl branch

Im waiting the feature to be supported as well

Good news everyone!

At some point, I will create a bot to match Jarred's tweet with github issues

This is now in a state we're happy with and will be available as of Bun v1.1.35, which will be out tomorrow Tue Nov 19 🎊

What about adding linuxmusl to CompileTarget?

Running bun build --compile --sourcemap --minify --target bun-linux-x64-modern src/index.ts on Alpine will fail with:

error: Unsupported compile target: bun-linux-x64-musl-v1.1.36

[nektro]

let's track that in a new issue
