React-native: Duplicate symbols after upgrading react-native

[fuzunspm]

🐛 Bug Report

Today after i upgraded my react-native via react-native-git-upgrade i'm getting duplicated symbols for libFolly.a and libReact.a files.

Edit: it works on android

Error Output

ld: 32 duplicate symbols for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

To Reproduce

building the app from xcode or by running react-native run-ios

Expected Behavior

able to build and run the app as before upgrading react-native

Code Example

Podfile

target 'AverageSpeedRN' do
    rn_path = '../node_modules/react-native'
    rn_maps_path = '../node_modules/react-native-maps'

    pod 'yoga', path: "#{rn_path}/ReactCommon/yoga/yoga.podspec"

      'RCTNetwork',
      'RCTSettings',
      'RCTText',
      'RCTVibration',
      'RCTWebSocket',
    ]

    pod 'DoubleConversion', :podspec => "#{rn_path}/third-party-podspecs/DoubleConversion.podspec"
    pod 'glog', :podspec => "#{rn_path}/third-party-podspecs/glog.podspec"
    pod 'Folly', :podspec => "#{rn_path}/third-party-podspecs/Folly.podspec"

    pod 'react-native-maps', path: rn_maps_path
    pod 'react-native-google-maps', path: rn_maps_path
    pod 'GoogleMaps' 
    pod 'Google-Maps-iOS-Utils'
    pod 'RNGestureHandler', :path => '../node_modules/react-native-gesture-handler'

    pod 'react-native-location', :path => '../node_modules/react-native-location'

  end

  post_install do |installer|
    installer.pods_project.targets.each do |target|
      if target.name == 'react-native-google-maps'
        target.build_configurations.each do |config|
          config.build_settings['CLANG_ENABLE_MODULES'] = 'No'
        end
      end
      if target.name == "React"
        target.remove_from_project

I'm having the same problem. Upgrading from a custom 0.56.0 build to 0.58.5

[reyalpsirc]

@fuzunspm Okay my project is working again
I just removed my Pods directory and the Podfile.lock and the run pod install again.

[fuzunspm]

I was trying to fix this for a few days but today I just gave up and removed iOS folder then re built it with tons of settings I had to configure but in the end it’s running again

[michalchudziak]

Hello there 👋 by using the repro / the list of steps to reproduce, we can't actually see the reported bug on RN 0.59.5 so we'll close this issue. It may have something to do with your local setup, please double check that you are using the correct version of Android Studio / XCode / Android NDK / Yarn / etc.

[luketgriffith]

had the same issue but @reyalpsirc 's fix worked for me

[noway]

You need to manually fix OTHER_LDFLAGS which is coming from pods config.

Browse Config file for the pods and remove -L"Folly" from there

[misterpoloy]

@noway This actually fix my issue, thanks! But also gave me the error library not found for -lDoubleConversion All this happened after a react-native update

[defghy]

For me, delete all Link Binary With Libraries and run pod install fix it;

[steinarsa]

For me, delete all Link Binary With Libraries and run pod install fix it;

@defghy That shit worked, have a rocket!

[jbethuel]

rm -rf Podfile.lock
pod deintegrate
pod install

works for me.

[thecodecafe]

For me, delete all Link Binary With Libraries and run pod install fix it;

@defghy Removing the linked binary causes the application not to build when developing, only when archiving, but the funny thing is I have Pods installed, so I don't understand why it's requiring the Linked Binary when building for development, also even if it archives when I remove the linked binaries I think it will only crash, when a user installs it. Will be going to 3 weeks now and I've been exactly here, done with my clients app but can't upload to the AppStore, I honestly am starting to look at using Flutter, RN has given me way too many problems developing, now I just feel stupid convincing my friends to learn RN instead of Flutter. Most things aren't explained and prior knowledge of how iOS or Android development works is just assumed when in reality most of the people who choose to use React Native are web devs who want to enter the mobile dev world, but I digress.

Do you mean to delete them from the Libraries folder or remove them from Link Binary in Build Phases?

@steinarsa Did you delete them from the Libraries folder or remove them from Link Binary in Build Phases?

Delete items from Link Binary in Build Phases works for me.

@tonynguyenit18 I was able to resolve my issue, here's the link to the answer on StackOverflow for anyone who tried everything here and it didn't work.

[rajeshsmallarc]

@defghy Thanks. Worked like a charm.

[kumarutsav111]

do not use pod install. instead, In Libraries folder drag .xcodeproj of the library from node modules. This helped me and it always works.

[laurentrivard]

I upgraded to RN0.60.4, and I had to delete every *.a file in Link Binary with Libraries manually. I then ran pod install so that only libPods-{projectName}.a was on that list and everything is back to building normally! Hope this helps
