Build error when adding crate `cpal` #2203

Closed zhpixel517 closed 1 month ago

Describe the bug

I'm trying to use the cpal crate for some DSP and audio processing in my flutter app. However, when I try to upload the app to a physical iOS device, I get this error: 

Launching lib/main.dart on chorb in debug mode...
Automatically signing iOS for device deployment using specified development team in Xcode project: 27J95Y9584
Xcode build done.                                            9.3s
Failed to build iOS app
Could not build the precompiled application for the device.
Error (Xcode): Undefined symbol: _AudioComponentFindNext

Error (Xcode): Undefined symbol: _AudioComponentInstanceDispose

Error (Xcode): Undefined symbol: _AudioComponentInstanceNew

Error (Xcode): Undefined symbol: _AudioUnitInitialize

Error (Xcode): Undefined symbol: _AudioUnitRender

Error (Xcode): Undefined symbol: _AudioUnitSetProperty

Error (Xcode): Undefined symbol: _AudioUnitUninitialize

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

I know for a fact that cpal supports iOS, so my thought was that there must be some configuration issue here with my Flutter application. I also went into Xcode > Build Phases > Link Binary With Libraries and added CoreAudio.framework to the list, still no luck. I'm not sure what I am doing wrong.

Steps to reproduce

run cargo add cpal, run the code generator again, and try uploading the app to a physical device

Hi! Thanks for opening your first issue here! :smile:

fzyzcjy commented 1 month ago

Hi, it looks like errors related to rust compilation instead of frb core, thus maybe good to check/ask in cargokit or rust itself. Also, maybe search the history issues https://github.com/fzyzcjy/flutter_rust_bridge/issues?q=%22cpal%22, since there are some people who successfully use cpal iirc.

zhpixel517 commented 1 month ago

Fixed the build error from this issue. In my case I had to remove the -framework AudioUnit flag. Sorry I should have checked that one haha. I'm still a little skeptical of cpal working correctly on iOS, but I'll be sure to open an issue if I run into anything (after a more thorough look at existing issues) :)

fzyzcjy commented 1 month ago

Happy to see it works!

but I'll be sure to open an issue if I run into anything

Sure :)
