Need help with this build error - BTOUCH : error BI0000: Unexpected error #20609

Hi,

I am creating an iOS binding library for a native library from https://github.com/FutureWorkshops/RANDA-RulesOfGolf-iOS-PodRepo.

I could not get past this error and there are no other details on why it is failing

BTOUCH : error BI0000: Unexpected error - Please file a bug report at https://github.com/xamarin/xamarin-macios/issues/new [/Users/kennethylaya/Projects/RANDARulesOfGolf.iOS/RANDARulesOfGolf.DotNet.Bindings/RANDARulesOfGolf.DotNet.Bindings.csproj]

Steps to Reproduce

  1. Built the native framework as described in the README from https://github.com/FutureWorkshops/RANDA-RulesOfGolf-iOS-PodRepo
  2. Create an iOS Binding library project in VS for Mac.
  3. Add a reference to the framework.
  4. Build the iOS binding library project.

Expected Behavior

Compiles successfully and creates an iOS binding library DLL that can be reference in the .NET for iOS project.

Actual Behavior

BTOUCH : error BI0000: Unexpected error - Please file a bug report at https://github.com/xamarin/xamarin-macios/issues/new [/Users/kennethylaya/Projects/RANDARulesOfGolf.iOS/RANDARulesOfGolf.DotNet.Bindings/RANDARulesOfGolf.DotNet.Bindings.csproj]

Can you try with this ApiDefinition.cs?

ApiDefinition.cs.zip

Changes:

  1. Remove any constructors taking an NSCoder argument: these constructors are already automatically generated, so there's a duplicate member error.
  2. Don't inherit from protocols in categories (this might be a bug on our side, I'll have to investigate a bit more).
  3. Comment out ROGTabBarController.SupportedInterfaceOrientations - this is the property causing the reported exception - because it seems to conflict somehow with the definition on the base type UITabBarController (this is certainly a bug, I'll investigate this too).

Note to self: test cases implemented here: https://github.com/rolfbjarne/xamarin-macios/commit/b4ecdad02a67a7600a18aee571dece418ecf223b

@rolfbjarne Thanks for your feedback and sending the updated ApiDefinition.cs file. The iOS bindings project compiles successfully now but I can't seem to use the library on my app, it just crashes.

I have created a simple .NET iOS app and referenced the bindings library project but it crashes due to this runtime error (full message is in the attached text file)

nz.co.golf.mygolf: 72190 dyld[72190]: Library not loaded: @rpath/DTCoreText.framework/DTCoreText

RoG-runtime.log.txt

Is DTCoreText.framework another native library that needs a bindings library?

Also, I have attached my solution (Test app and the bindings library) for reference. Archive.zip

The relevant text is:

Library not loaded: @rpath/DTCoreText.framework/DTCoreText
  Referenced from: [...]/RandRulesOfGolfTestApp.app/Frameworks/RANDARulesOfGolf.framework/RANDARulesOfGolf

So DTCoreText.framework is referenced from RANDARulesOfGolf.framework, and as such must also be included in the app somehow. The easiest way to do this is to add it to the same binding project as another NativeReference (unless you need to call any of the APIs in this framework from managed code, you shouldn't need to do anything else).

Thanks @rolfbjarne - hope to get back on this next week.
