RCT-Folly error when using hermes with iOS

Question

When enabling hermes in the Podfile and rebuilding the build it fails due to RCT-Folly. No idea what it does.

To re-initialise everything I use the following:

rm -rf node_modules && rm package-lock.json && npm install && cd ios && rm -rf Pods && rm Podfile.lock && pod deintegrate && pod setup && pod install && cd ..

I also start the metro bundler with:

npx react-native --reset-cache

Anyone has a solution?

The app uses react-native v0.64 and we want to have a better performance using hermes.

Answer 1

XCode 15 introduced breaking changes to its C++ compiler that caused all kinds of havoc with the React Native iOS build process.

Upgrading to react-native 0.72.5 addressed this issue for me. React Native team indicated the fixes are coming to other lower versions as well soon including 0.70.

If upgrading is not an option, you may be able to work around this by adding the following to Podfile:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)', '_LIBCPP_ENABLE_CXX17_REMOVED_UNARY_BINARY_FUNCTION']
    end
  end
end

Answer 2

It seems like you've changed the version of the dependency RCT-Folly somehow, it could happend when user try to copy podfile or dependencies from other existing project and it differs from the version stored in Pods/Local Podspecs. You should run pod update RCT-Folly --no-repo-update to apply changes made locally. if this is your case then try this command

pod update RCT-Folly --no-repo-update

Answer 3

Another solution is to run:

pod update && pod install

this should fix the issue.

Answer 4

I have find one simple solution for react native project run on mac m1 chip. you are try multiple solution to run a project so some config change on your current project, so easy solve

1. create new project npx react-native init Project_name. And do not run your project instantly
2. To navigate to pod file comment # use_flipper!().
3. pod install
4. npx react-native run-ios

Answer 5

I deleted Podfile.lock, then npx pod-install. That solved my problem

Answer 6

I'm on a 2020 M1 Apple MacBook and none of these solutions worked for me. The folder where I had the project created in was named 'React Native' with a space in-between. Apparently that had an adverse effect on running the pod install properly. I renamed the folder to 'React_Native' and ran pod install and everything started working.

Answer 7

What worked for me:

I'm using react native version 0.67.3 MacOS Monterey(Intel Mac)

1.Open the project in Xcode using the .xcworkspace file 2.Run the app from Xcode.

Seems to work without the error.

Answer 8

The solution is to remove white spaces from project root folders.

See below:

Project/ReactNative/MySampleProj

Answer 9

I faced some errors for this version { 'Flipper' => '0.87' }

So I have done some changes and this Podfile setup is working for me

use_flipper!({ 'Flipper-Folly' => '2.5.3', 'Flipper' => '0.87.0', 'Flipper-RSocket' => '1.3.1' })

  post_install do |installer|
    react_native_post_install(installer)
    flipper_post_install(installer)

     find_and_replace("Pods/Headers/Private/RCT-Folly/folly/synchronization/DistributedMutex-inl.h",
     "atomic_notify_one(state)", "folly::atomic_notify_one(state)")

     find_and_replace("Pods/Flipper-Folly/folly/synchronization/DistributedMutex-inl.h",
     "atomic_wait_until(&state, previous | data, deadline)", "folly::atomic_wait_until(&state, previous | data, deadline)")
  end
end

Answer 10

After lots of trial and error I found a working solution. It's a bit strange, but I had to enable Flipper. I did not find a way without it.

Thanks to this answer: https://github.com/facebook/react-native/issues/31179#issuecomment-831932941 I found out about fixing Pods.

This is my Podfile now:

  ...

  # Enables Flipper.
  #
  # Note that if you have use_frameworks! enabled, Flipper will not work and
  # you should disable these next few lines.
  use_flipper!({ 'Flipper' => '0.87' })
  post_install do |installer|
    flipper_post_install(installer)

    find_and_replace("Pods/Headers/Private/RCT-Folly/folly/synchronization/DistributedMutex-inl.h",
    "atomic_notify_one(state)", "folly::atomic_notify_one(state)")

    find_and_replace("Pods/Flipper-Folly/folly/synchronization/DistributedMutex-inl.h",
    "atomic_wait_until(&state, previous | data, deadline)", "folly::atomic_wait_until(&state, previous | data, deadline)")
  end
