Consuming a Static Library created in c++ in MAUI for iOS Deployment.

Question

Hello,

I have a c++ library that is for Signal Processing. This is being built for arm64, arm64e. I have created an iOS Binding Library that consumes *.a static library and imports methods.

I am referencing this binding library in my MAUI Project.

I have paired Visual Studio on Windows with a M1 MAC and an iOS Device is connected. I am trying to deploy on this iOS device, but when I build the MAUI Project I am getting below error:

===================

clang++ exited with code 1:

Undefined symbols for architecture arm64:

  "_Analysis", referenced from:

      <initial-undefines>

  "_SetTestConfig", referenced from:

      <initial-undefines>

  "_Startup", referenced from:

      <initial-undefines>

 

ld: symbol(s) not found for architecture arm64

 

clang++: error: linker command failed with exit code 1 (use -v to see invocation)

 ===================

The static library was previous being used in Xamarin.iOS and it was working correctly. This is a Migration project.

Answer 1

Hello,

clang++: error: linker command failed with exit code 1 this error means that some method(_Analysis,_SetTestConfig,_Startup) is referenced that does not have an implementation in the arm64 binary (.a file) or some objects are null. The root issue is in the library.

You could check these methods in your library and see if they are not implemented.
