ERROR: Undefined symbols for architecture arm64: "_OBJC_CLASS_$_TealiumReactNative"

[Fedd9]

Hello everyone, we're having a problem related to a RN migration from v0.63 to v0.73: while upgrading all the libraries and used frameworks, we've encountered this error:

Undefined symbols for architecture arm64: "_OBJCCLASS$_TealiumReactNative", referenced from: objc-class-ref in libtealium-react-native.a(TealiumReactNative.o) _OBJC$_CATEGORYTealiumReactNative$_RCTExternModule in libtealium-react-native.a(TealiumReactNative.o) "_OBJCCLASS$_TealiumWrapper", referenced from: objc-class-ref in libtealium-react-native.a(TealiumReactNative.o) _OBJC$_CATEGORYTealiumWrapper$_RCTExternModule in libtealium-react-native.a(TealiumReactNative.o) ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

Now, considering everything, we managed to understand a solution related ([https://github.com/Tealium/tealium-react-native/issues/129]) but this is not working for us.

pre_install do |installer|
    Pod::Installer::Xcode::TargetValidator.send(:define_method, :verify_no_static_framework_transitive_dependencies) {}

    installer.pod_targets.each do |pod|
      if pod.name.start_with?('tealium-react-native')
        def pod.build_type;
          Pod::BuildType.static_library # >= 1.9
        end
      end
    end
  end

We can't use use_frameworks! :linkage => :static because it is not compatible with Flipper. For reference, I'm also attaching the podfile.

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

platform :ios, '13.4'
prepare_react_native_project!
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

Hope you can help me

@Fedd9 sorry for the delayed reply. We are looking into this for you.

[trne]

is there any update on this?

[Enricoza]

It looks like this issue was missed, sorry about that. @Fedd9 and @trne were you able to resolve it?

By having a look at your Podfile it seems that you are missing a line:

  pod "tealium-react-native-swift", :path => '../node_modules/tealium-react-native/tealium-react-native-swift.podspec'

That is necessary starting from tealium-react-native 2.2.0 onwards as written in the documentation here.

Let us know if you are still facing the issue and sorry again for missing this.
