Typedef redefinition with different types ('uint8_t' (aka 'unsigned char') vs 'enum clockid_t') #5504

🐛 Bug Report

When I build my react native projection XCode I get the following error:

/Users/owhittlef/code/Parea/ios/Pods/Headers/Private/RCT-Folly/folly/portability/Time.h:52:17 Typedef redefinition with different types ('uint8_t' (aka 'unsigned char') vs 'enum clockid_t')

When I try to run npm run ios I get another error. I believe this one's related with Flipper-Folly but not sure. The error is

The following build commands failed:
    CompileC /Users/owhittlef/Library/Developer/Xcode/DerivedData/Parea-fvqmxpilfyeylsflhumwxfsffatn/Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/RCT-Folly.build/Objects-normal/arm64/TimeoutManager.o /Users/owhittlef/code/Parea/ios/Pods/RCT-Folly/folly/io/async/TimeoutManager.cpp normal arm64 c++ com.apple.compilers.llvm.clang.1_0.compiler (in target 'RCT-Folly' from project 'Pods')

To Reproduce

Create a new react native project and try to build. I have included all of my specific packages and configurations in the following section.

Environment

My Podfile:

# Resolve react_native_pods.rb with node to allow for hoisting
require Pod::Executable.execute_command('node', ['-p',
  'require.resolve(
    "react-native/scripts/react_native_pods.rb",
    {paths: [process.argv[1]]},
  )', __dir__]).strip

platform :ios, 13.0
prepare_react_native_project!

# If you are using a `react-native-flipper` your iOS build will fail when `NO_FLIPPER=1` is set.
# because `react-native-flipper` depends on (FlipperKit,...) that will be excluded 
#
# To fix this you can also exclude `react-native-flipper` using a `react-native.config.js`
# ```js
# module.exports = {
#   dependencies: {
#     ...(process.env.NO_FLIPPER ? { 'react-native-flipper': { platforms: { ios: null } } } : {}),
# ```
flipper_config = ENV['NO_FLIPPER'] == "1" ? FlipperConfiguration.disabled : FlipperConfiguration.enabled

linkage = ENV['USE_FRAMEWORKS']
if linkage != nil
  Pod::UI.puts "Configuring Pod with #{linkage}ally linked Frameworks".green
  use_frameworks! :linkage => linkage.to_sym
end

target 'Parea' do
  config = use_native_modules!

  use_react_native!(
    :path => config[:reactNativePath],
    # Enables Flipper.
    #
    # Note that if you have use_frameworks! enabled, Flipper will not work and
    # you should disable the next line.
    :flipper_configuration => flipper_config,
    # An absolute path to your application root.
    :app_path => "#{Pod::Config.instance.installation_root}/.."
  )

  target 'PareaTests' do
    inherit! :complete
    # Pods for testing
  end

Getting same error on RN 0.73.8, XCode 15.3. Did you solve it?

nguyendinhdoan commented 5 months ago

I have the same issue. The code below used to work for me:

installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '13.4'
      config.build_settings["ONLY_ACTIVE_ARCH"] = "NO"
      `sed -i -e $'s/__IPHONE_[0-9][0-9]_[0-9]/__IPHONE_14_0/' Pods/RCT-Folly/folly/portability/Time.h`
    end
  end

Upgrading to RN 0.74 solved it for me
