Alpine linux - symbol not found while launch

[quolpr]

Gem was installed, but when rails is launching I get the error:

LoadError: Error relocating /usr/local/bundle/gems/mini_racer-0.1.12/lib/mini_racer_extension.so: __fprintf_chk: symbol not found - /usr/local/bundle/gems/mini_racer-0.1.12/lib/mini_racer_extension.so

Hello @quolpr, thank you for taking the time to file this issue.

Could you please paste the output of gem env for the system you are experiencing the issue on?

[quolpr]

@ignisf yes, of course:

Ah, I see

  - RUBYGEMS PLATFORMS:
    - ruby
    - x86_64-linux

Your error is probably due to rubygems downloading a version of the libv8 gem linked against glibc. Please take a look at the note here for more info: https://github.com/cowboyd/libv8#use-with-different-standard-c-libraries.

You could try to lock the libv8 version to the latest source release and try again. See https://github.com/cowboyd/libv8#source-and-binary-releases for more info.

I'm hoping that at some point there will be a mechanism for us to provide musl-linked binaries :(. Unfortunately at this point rubygems has no such feature.

Wow, thank you! I think your solution will work, but I can't test it :(. We took Debian-slim instead and everything work fine. When I will use alpine - I will test it.

Big thanks!

Closing this for now as it is in essence not a bug in mini_racer :)
