Description paubreil 2017-06-07 15:05:34 UTC

The error is :

Comment 1 Timothy Risi 2017-06-07 21:42:44 UTC
Hello,

Do you have a simple repro case you could share?  Full environment info would also be helpful.

Easiest way to get exact version information:
 - On Visual Studio for Mac: "Visual Studio" menu, "About Visual Studio" item, "Show Details" button.
 - On Visual Studio for Windows: "Help menu", "About Microsoft Visual Studio" item.
 Then copy/paste the version information (you can use the "Copy Information" button).

I was able to get my app to successfully compile by using the iOS Build Option -> Linker Behavior -> "Don't Link"
Comment 4 paubreil 2017-06-15 09:02:17 UTC
Hello, 
Sorry I don't know this is the same error.
The problem you show is only a warning which doesn't affect the build.

I think it come from a biding problem between iOS and Xamarin like that lines :

 Undefined symbols for architecture arm64:
      "_AVCaptureSessionPreset1280x720", referenced from:
          -[ZebraSDA init] in libZebraSDA.a(libZebraSDA.a.bc.o)
      "_AVCaptureSessionPresetHigh", referenced from:
          -[ZebraSDA init] in libZebraSDA.a(libZebraSDA.a.bc.o)
          -[ZebraSDA viewDidLoad] in libZebraSDA.a(libZebraSDA.a.bc.o)
      "_AVLayerVideoGravityResizeAspectFill", referenced from:
          -[ZebraSDA viewDidLoad] in libZebraSDA.a(libZebraSDA.a.bc.o)
      "_AVMediaTypeVideo", referenced from:

          -[ZebraSDA observeValueForKeyPath:ofObject:change:context:] in libZebraSDA.a(libZebraSDA.a.bc.o)

These class exist in Xamarin but with name AVCaptureSession.Preset1280x720 not in single word.
can it be a MTOUCH bug binding?
Comment 5 Rolf Bjarne Kvinge [MSFT] 2017-06-15 10:16:39 UTC
This is a problem with the binding project: it needs to state that the native library requires AVFoundation, CoreGraphics, and UIKit.

This is done by adding the following to the LinkWith attribute for the native library:

    [assembly: LinkWith (..., Frameworks = "AVFoundation CoreGraphics UIKit")]
Comment 6 paubreil 2017-06-15 14:16:20 UTC
Hello,
Thank you to your help , this solve my first bug

I add to my libZebraSDA property the Framework : AVFoundation CoreGraphics UIKit CoreMedia Security CoreVideo SystemConfiguration MobileCoreServices
And I add the Linker Flag : -lz -lstdc++  too

But I still have one bug :

Can you execute the following command (copy/paste, it's a single line) in a terminal and see if you get the same error or if it works:

Hello,

Your command doesn't work but I found the solution by removing the isC++ parameter from the libraries properties.
With that , it remove the -lgcc_eh command then the library is importing successful.

Thank you all.
