Question

I started with a functioning bindings project, but I needed to add a global int for a status flag and I can’t get it to bind without error. I started with the sample code and can’t get this to work.

The code I add to my bindings file is:

[Static]
interface CameraEffects {
    [Field ("kCameraEffectsZoomFactorKey", "CameraLibrary")]
    NSString ZoomFactorKey { get; }
}

I get three errors:

obj/Debug/ios/PDFExpert/CameraEffects.g.cs(34,94): error CS0117: `MonoTouch.Constants' does not contain a definition for `CameraLibraryLibrary'
obj/Debug/ios/PDFExpert/CameraEffects.g.cs(34,76): error CS1502: The best overloaded method match for `MonoTouch.ObjCRuntime.Dlfcn.dlopen(string, int)' has some invalid arguments
obj/Debug/ios/PDFExpert/CameraEffects.g.cs(34,76): error CS1503: Argument `#1' cannot convert `object' expression to type `string'

If I leave the library off it tried to assign it to another unknown constant. This seems really screwed up as it is strait from the documentation.

Answer 1

I guess this should be bound like this

[Static]
interface CameraEffects {
    [Field ("kCameraEffectsZoomFactorKey", "__Internal")]
    NSString ZoomFactorKey { get; }
}

This is due to on the final app, the executable and the libxxx.a will be linked and merged together so it should work.
