Error (Xcode): duplicated symbols `_wrapped_os_log_error` #2271

Closed patmuk closed 2 weeks ago

patmuk commented 2 weeks ago

Describe the bug

after code generation, when I run flutter run I get this error:

Launching lib/main.dart on iPhone 15 in debug mode...
Running pod install...                                             660ms
Running Xcode build...                                                  
Xcode build done.                                           14.2s
Failed to build iOS app
Error (Xcode): 7 duplicate symbols

Error (Xcode): Linker command failed with exit code 1 (use -v to see invocation)

Could not build the application for the simulator.
Error launching application on iPhone 15.

Steps to reproduce

flutter pub get
flutter_rust_bridge_codegen generate --config-file flutter_rust_bridge.yaml
dart run build_runner build
flutter run

I did this on my own project, not the frb sample, but after upgrading to the latest frb version. Any idea what might be the issue? Or how I can debug this?

First guess: Is it possible because of https://github.com/fzyzcjy/flutter_rust_bridge/pull/2245?

You can disable log feature to avoid compiling that log lib and keep it the old way.

But I wonder why it will have "duplicated symbols"... One wild guess: is it possible you setup your logging, and thus this other logging somehow conflicts?

patmuk commented 2 weeks ago

Oh, that is a very good tip! Indeed, I set up my own logging, and I saw the logging support in the changelog - but did not connect the dots.

I will change that later and reply to this issue!

patmuk commented 2 weeks ago

Yes, that was the issue! I created an instance of the OsLogger - and had the crate specified in the cargo.toml. I assume that this lib got added twice, resulting in duplicated symbols.

Code removed, problem solved. Thanks!
