Musl LibC Support

Open theoparis opened this issue 3 years ago • 12 comments

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 :+1: to the first post instead of adding "me too" comments :pray:

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

Easy to compile against musl libc. I need motivation to write a "normal" patch, but its possible. This requires: add musl flag to tcc build in Makefile -fPIC in build.zig turn off checking GLIBC version in build.zig turn off force GLIBC in workaround-missing-symbols.cpp rebuild JSCore

If you are trying to build using only clang, some additional patches are required.

Tested and works well for musl+clang image

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.

Great. Could you please upload the binary so that I can temporarily use?

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

@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?
