Description

This is a continuation of issue #22945. It was closed out before I got a chance to provide additional info.

I feel that there is probably something wrong in my environment but cannot find it. (I have listed the details of my installation below)

Whenever pair-to-mac is active, it fails with "CreateBindingResourcePage" and I do not get a .dll in the bin folder. An AudioKitFrameworkProxyCore.Binding.dll only got created when "Pair-to-mac" was off (I didn't realize this is what had happened when I created #22945). Of course the dll is empty and is only 15 KB in size.

When Pair-to-Mac is active, the build fails with the message below. This doesn't make sense because the file it's looking for "arm64-apple-ios.swiftdoc" I believe is supposed to be created during the build process (note: I can create a basic MAUI app project from the template, build it and run it from the same Mac.):

Am I missing something in my setup or are there some incompatibilities with what I'm using?

Steps to Reproduce

Create a binding project and build against the same runtimes/sdks listed above.

Did you find any workaround?

No response

Build logs

No response

This looks like a MAX_PATH issue.

Enabling long paths in Windows might work around it, although potentially only when building from the command line. If that's the case, one workaround is to build on the Mac, and consume the binding dll/nuget from Windows instead of using the binding project as a project reference.

Can you try that and see if that works?

Hi @@sethom. We have added the "need-info" label to this issue, which indicates that we have an open question for you before we can take further action. This issue will be closed automatically in 7 days if we do not hear back from you by then - please feel free to re-open it if you come back to this issue after that time.

This was caused by the path to arm64-apple-ios.swiftdoc on my system being too long. I guess this can't be longer than 255 characters for Visual Studio. After copying the solution to c:\ this error went away.
