duplicate symbols for architecture x86_64

[mikehardy]

Hi there! You might try npx react-native-clean-project after making absolutely sure that you have removed the old version so there are not two. Then after that command re-try pod install and rebuild

[tarasvakulka]

@srfaytkn I look forward to your reproducible example. Until then though, how exactly should anyone trying to help you proceed 🤔 ? (rhetorical question: no one should burn any time trying to reproduce someone else's problem, it is on you the reporter, to cleanly reproduce it and demonstrate it)

Reproducible example: https://github.com/tarasvakulka/RnFbsdkExample.git

Looks like needed update FacebookSdk to 11.0.1 in react-native-fbsdk-next, because FBSDKCoreKit (9.3) from react-native-fbsdk-next and FBSDKCoreKit_Basics (11.0.1) from FBAudienceNetwork (6.5.1) make duplicate symbols:

duplicate symbol '_FBSDKAppEventExternalId' in:
/Users/username/Library/Developer/Xcode/DerivedData/RnFbsdkExample-embqdzudpolhhtbozqhfuvgazhef/Build/Products/Debug-iphonesimulator/FBSDKCoreKit/libFBSDKCoreKit.a(FBSDKUserDataStore.o)
/Users/username/Library/Developer/Xcode/DerivedData/RnFbsdkExample-embqdzudpolhhtbozqhfuvgazhef/Build/Products/Debug-iphonesimulator/FBSDKCoreKit_Basics/libFBSDKCoreKit_Basics.a(FBSDKUserDataStore.o)

Xcode: 12.5.1

For everyone who have this problem, just use FBAudienceNetwork (6.5.0) for compatibility with react-native-fbsdk-next (4.3.0)

The project finally build succeeded after i manually delete duplicate lib on FBSDKCoreKit_Basics. It's not fully fixed, because i should always do that after do pod install. Hopefully it will fully fixed on the next version. Thank you

[mikehardy]

fbads and fbsdk-next may conflict.
We need a https://stackoverflow.com/help/minimal-reproducible-example in order to investigate - best if based off a fork of this repo and the example provided

[mikehardy]

No, if it's the sdk update we're tracking that elsewhere. Obviously the sdk must be included once and only once, in a single version. This is an open source repository and it relies on community contributions, someone needs to forward port to sdk v11. Until then, you must use versions that line up on the v9 sdk

[mikehardy]

@srfaytkn it is closed for the reasons written above, and tracked authoritatively in the link to the forward-port needed here before you can start including newer versions of facebook-ios-sdk in other modules.

[mikehardy]

For anyone else reading this:

Until someone does the work to forward-port this module to facebook-ios-sdk newer versions ( ---> #55 ) you must ensure that all other modules use only the facebook-ios-sdk that this module is compatible with.

If you attempt to mix-and-match, whether you knew that is what you were doing or not, you will have this problem.

Thank you for your reply, but it still the same on me.

[mikehardy]

Unfortunately, unless you can reproduce this in the sample app (or a minimal reproducible example https://stackoverflow.com/help/minimal-reproducible-example) I must conclude this is a project-specific issue - specific to your project. I don't expect anything discovered here will result in a change in this module as the current version is working correctly in my projects and the example, so I'm not dedicating any effort to it personally.

[mikehardy]

Glad to hear you are moving forward. If you can make a reproducible example that shows the module's at fault we can fix something but otherwise I'd definitely dig into your project, something seems seriously wrong there if you have to manually do something

We deleted node_modules, Pods & Podfile.lock
Then did
yarn
cd ios && pod install --repo-update

The only thing being used from the app itself was just

import { Settings } from 'react-native-fbsdk-next';
Settings.initializeSDK();

[mikehardy]

@seamive "being used" != "compiled in with possibly duplicate symbols from different versions of things"

[srfaytkn]

i have the same issue as @jacow

[mikehardy]

@srfaytkn I look forward to your reproducible example. Until then though, how exactly should anyone trying to help you proceed 🤔 ? (rhetorical question: no one should burn any time trying to reproduce someone else's problem, it is on you the reporter, to cleanly reproduce it and demonstrate it)

[tarasvakulka]

@jacow @mikehardy Reopen this issue please.

[thebergamo]

We're eager to see new contributors :)

[mikehardy]

Note, a useful byproduct of your investigation could be a docs pr that tells people which versions of this lib and others all depend on ios sdk v9...

[mikehardy]

We're eager to see new contributors :)

Hear hear on that. I definitely have not had the time and may not ever have the time to do the v11 forward port. Here's the link though for completeness, apparently someone sort of had it working but then went silent and no PR 😭 #55

[AmirDoreh]

my problem starts when one of the packages i am usinng (Admost) start installing 'FBSDKCoreKit_Basics ~> 11.1' , then it makes tons of duplications which all of them are related to this .
how can i avoid manage it ?

[AmirDoreh]

why this issue is closed? @mikehardy

[srfaytkn]

@AmirDoreh you can try pod 'AMRAdapterFacebook', '~> 6.5.0.0

[AmirDoreh]

@srfaytkn Thanks for your offer , i directly started using your package for Admost.
