I copied the Project Template and experimented with the tutorial and successfully made some changes to the sample app.

 

My problem is when I add the .a library file that the barcode scanner provides I am getting link errors.  I added it to the Plugin.xcodeproj and it builds successfully but when I open up the App.xcodeproj and build I get the following error:

I have searched and searched and have tried changing various flags for Deadcode stripping, other linker flags, and library search paths.  

 

If I create a blank brand new xcode project and add the library and headers it builds fine.

 

Any ideas?

 

Thanks

If I add the library and header files to the App.xcodeconfig proj vs the plugin proj.  I get the following error:

For future reference I fixed it by adding an ExternalAccessory.framework reference to the project.

 

"_OBJC_CLASS_$_EASession", referenced from: error. It was fixed by adding ExternalAccessory.framework to Targets > myApp > Build Phases > Link Binary with Libraries
