RN62.0: Multiple targets match implicit dependency for linker flag '-lBugsnagReactNative

[enigmablue]

Description

I'm trying to upgrade my RN from 61.2 to 62.0

Issue

This looks like its causing my error

Multiple targets match implicit dependency for linker flag '-lBugsnagReactNative'. Consider adding an explicit dependency on the intended target to resolve this ambiguity. (in target 'app' from project 'app')

During archiving this is caused

Build system information
error: Multiple commands produce '/Users/runner/Library/Developer/Xcode/DerivedData/soqqle-dwfbawsdshbrmlchzzthidlmmbmv/Build/Intermediates.noindex/ArchiveIntermediates/app/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/libBugsnagReactNative.a':

I have tried to google but dosen't seem like its anywhere clear. Its only happening to bugsnag, and also realm. Anyone has tips?

Environment

Library versions:

├─ bugsnag-react-native@2.23.10
├─ react-native-code-push@6.1.1
└─ react-native@0.62.0

I'm using the new build system

• cocoapods version (if any) (pod --version):1.9.3

Hey @enigmablue, looks like the Bugsnag library is trying to be linked twice. Can you please share your Podfile for us to take a look?

There are also a large variety of different reasons this error can be seen, a lot of the solutions are discussed in this Stack Overflow thread: https://stackoverflow.com/questions/50718018/xcode-10-error-multiple-commands-produce do any of these solutions fix your issue?

Additionally, it may be worth cleaning out your React Native project, there are tools like https://www.npmjs.com/package/react-native-clean-project which can help with this, to ensure there are no multiple installations of these libraries.

Hi!

My podfile is just like this. Its only happening if i use the new build system. When i revert to the legacy it works fine. But i dont know the main differences between legacy vs new build system. (i have seen that thread and i have gone through them before).

I heard about the clean project today too. I'd give that a shot.

Thanks @enigmablue, we suspect it's a problem that can be solved by cleaning your build environment. In addition to the clean tool above, you may want to use XCode to clean out your ios dir:

$ cd ios
$ xcodebuild clean

thanks man i tried both the xcode clean and cleanproject but it didn't really help. but eventually i found the error. I had a duplicate xcodeproj in my libraries on the project folder. Deleted them and it worked. I found out because i did a fresh project init and compared the settings one by one.

My previous dev created them when we upgraded to RN60, and i dont think he knew what he was doing.
