I'm using the latest version of glibc

The problem appears to be in the includes declared in mini_racer's ext/mini_racer_extension/mini_racer_extension.cc file which was fixed in https://github.com/discourse/mini_racer/commit/c9f141b58eac9ef293237bcda1c3929b2d3b5c6f.

[sgerrand]

Ah, ignore my previous comment. That relates to an issue I had installing the mini_racer gem to reproduce the issue.

[sgerrand]

I can only find one reference to fprintf in the mini_racer gem's ext/mini_racer_extension/mini_racer_extension.cc file. Have you tried recompiling the gem?

[fusillicode]

Same problem here and it's kind of sad :( Because of this I can not build a react-on-rails app :(

[3den]

same problem

[ggwzrd]

I also have the same problem, is this issue solved?

[mosheka]

Same here :-(

[mosheka]

Same here :-( In the meantime another soluton by be using multistage builds, and do the assets precompile on ubuntu and copy the results to alpine

[benoist]

I'm also running in to this problem

[Antiarchitect]

Same for me.

Hello all!

mini_racer depends on the libv8 gem which distributes a statically linked (against glibc) V8. At this point rubygems has no support for distributing binary gems that are linked against a specific standard library :(. I would really like to see this implemented there so I can release libv8 linked against musl.

Please take a look at these sections in libv8's README. I hope they're helpful for you:

https://github.com/cowboyd/libv8#use-with-different-standard-c-libraries

https://github.com/cowboyd/libv8#source-and-binary-releases

[andreimc]

Any work arounds for this ?

[sgerrand]

Not unless you can make the debugging symbols being referenced available to the runtime. Without those this will continue to happen.

[andreimc]

Is there a way to compile libv8 from source with the symbols?

[ignisf]

@andreimic, how exactly do you want to do that? Make Rubygems compile the gem from source or create a binary .gem file you can distribute?

[ignisf]

You can do both.

I have the same problem. But, btw, would asset-precompilation on ubuntu, and copying to the main image (that uses alpine) work?

It's worth trying. 👍
