dyld: Symbol not found: __ZN2v82V813InitializeICUEPKc

This occurs when server-rendering from React component.
The gem install command actually works fine.

Any idea what I can do here to debug?

Could this be a duplicate of #169?

This is on Mac OSX so it doesn't seem to be the case.

I am getting the same error on Mac OSX with an M1 chip (arm64). I also tried ruby 2.7.0 and 2.6.6 und tried installing mini_racer and libv8 as x86_64 with arch -x86_64 bundle install but had no luck

I had this issue as well with my Rails 6.1.1 Install on Apple Silicon.
I managed to get it fixed by updated to a beta version of mini_racer, and also updating Ruby to v2.7.2.

here's the relevant thread:
rubyjs/libv8-node#14

and the beta build for your Gem file:

# Gemfile
gem 'mini_racer', github: 'rubyjs/mini_racer', branch: 'refs/pull/186/head'
# or
gem 'mini_racer', github: 'sqreen/mini_racer', branch: 'use-libv8-node'

Is the issue still resolved for you, @sweetppro using the latest released version of mini_racer?

yup I'm running mini_racer (0.4.0) without any issues

[tisba]

There have been a ton of updates/fixes with current mini_racer versions. Can you check if the current 0.6.2 solves your issue, @Overload119?

[Overload119]

No longer can reproduce.

@tisba I found this thread because I've been fighting this same issue for 2 days on version 0.6.2 using an Intel Macbook Pro OSX Big Sur and more recently Monterey. The error I was getting on Monterey when attempting to start a rails server was

1: from /Users/kevin/.rvm/gems/ruby-2.7.5/gems/mini_racer-0.6.2/lib/mini_racer.rb:11:in `<main>'
/Users/kevin/.rvm/gems/ruby-2.7.5/gems/mini_racer-0.6.2/lib/mini_racer.rb:11:in `load': dlopen(/Users/kevin/.rvm/gems/ruby-2.7.5/extensions/x86_64-darwin-20/2.7.0/mini_racer-0.6.2/mini_racer_extension.bundle, 0x0005): symbol not found in flat namespace '__ZN2v811ArrayBuffer9Allocator19NewDefaultAllocatorEv' (LoadError)

Because @sweetppro said 0.4.0 worked for him I figured I would give that a shot

Is the issue still resolved for you, @sweetppro using the latest released version of mini_racer?

yup I'm running mini_racer (0.4.0) without any issues

I'm finally able to run my rails app again using mini_racer 0.4.0 where I could not on 0.6.2.

[tisba]

@scruff311 that's really odd. I'm on Monetery 12.1 (intel/x86), also using RVM like you and with Ruby 2.7.5, mini_racer 0.6.2 and libv8-node 16.10.0.0 it just works.

Can you tell us some more about your environment?

• Ruby: ruby --version (for me ruby 2.7.5p203 (2021-11-24 revision f69aeb8314) [x86_64-darwin21])
• Rubygems: gem --version (for me 3.1.6)
• GCC: gcc --version (for me Apple clang version 13.0.0 (clang-1300.0.29.30))
• gem list libv8-node mini_racer

The only thing I can think of at this time is to re-install mini_racer and libv8-node. If that doesn't help I'm lost /cc @SamSaffron

[tisba]

It's a stretch, but could you remove all versions of mini_racer and libv8-node and try 0.6.2 again? Just want to make 100% sure that not the wrong version of libv8-node gets picked up during compilation of mini_racer.

[tisba]

I noticed something else: Your ruby --version states x86_64-darwin20 as platform, but gcc says x86_64-apple-darwin21.3.0. Did you build 2.7.5 from source? maybe on an earlier version of macOS?

[scruff311]

🤯 i uninstalled mini_racer, libv8-node and sq_mini_racer and then reinstalled them and amazingly it now works with 0.6.2. I had uninstalled mini_racer countless times, but i guess i never also uninstalled libv8-node at the same time.

To answer your question, my Ruby 2.7.5 was installed with RVM when my mac was still on Big Sur (darwin-20). I have since updated to Monterey (darwin-21).

Thanks for your help!

[tisba]

Awesome! 🎉

I'm collecting these kinds of issues currently to compile a troubleshooting guide. This platform difference is an important piece of it!

[cjoulain]

Thank you for documenting these steps, @scruff311. I tried what you did (I was only uninstalling mini_racer) and was able to get my local working again.

@tisba When I run my local Rails server, I encounter this:

/Users/cj/.rbenv/versions/3.1.1/lib/ruby/gems/3.1.0/gems/mini_racer-0.6.2/lib/mini_racer.rb:11:in `load': dlopen(/Users/cj/.rbenv/versions/3.1.1/lib/ruby/gems/3.1.0/extensions/arm64-darwin-21/3.1.0/mini_racer-0.6.2/mini_racer_extension.bundle, 0x0005): symbol not found in flat namespace '__ZN2v811ArrayBuffer9Allocator19NewDefaultAllocatorEv' (LoadError)

I previously encountered this error while upgrading to Ruby 3.0.0 last month. I've just upgraded to Ruby 3.1.1. I was able to clear up this issue last time by uninstalling mini_racer and libv8-node at the same time. However, it didn't work this time around.

Any tips?

@cjoulain are you 100% certain that you've compiled Ruby, mini_racer and/or libv8-node on your current macOS (12.3 I would guess based on gcc --version). Any cases I know of for these errors are related to OS upgrades.

[cjoulain]

Thanks for checking in, @tisba. I had to uninstall and reinstall almost 10 times for my repo to work again. I can't say what helped -- it working again was arbitrary. But I did compile all three. Since you mention it's OS-related, I won't reach out here if it happens again.

[tisba]

I'm running out of ideas then :(

Is there some way to further analyse what's going on here, @SamSaffron/@lloeki?

[Saya221]

In my case, I resolved the issue by updating my clang++, clang, c++, gcc, and g++ on macOS to Apple Clang. Here's the setup for g++, gcc, and c++ in .bashrc or .zshrc files. Please ensure these lines are placed at the beginning of file:

# C++, Clang++, G++, GCC
export CXX=/usr/bin/clang++
export CC=/usr/bin/clang

# Adjust PATH to prioritize /usr/bin
export PATH="/usr/bin:$PATH"

After making these changes, check the versions of the following:

gcc -v
g++ -v
c++ -v
clang -v
clang++ -v

Apple clang version 14.0.0 (clang-1400.0.29.202)
Target: x86_64-apple-darwin21.6.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

Ensure that the versions match Apple Clang, as this error is likely caused by our compilation. Finally, restart machine, reinstall mini_racer, and it should work fine.
