Comment 1 Sebastien Pouliot 2013-08-15 08:04:49 UTC
There's likely a binding mistake that trigger the bug. Can you attach your binding source files ? (you can mark them private) so we can reproduce the issue and ensure we report a more useful error ? Thanks
Comment 2 Claudiu T 2013-08-15 08:13:09 UTC
Bonjour Sebastien,

Thank you for the quick reply. I actually find the error myself early this morning, but I just didn't have time to update this bug. All is good now, so should I just change the status to Resolved | Invalid?

Thanks
Comment 3 Sebastien Pouliot 2013-08-15 08:22:31 UTC
I'd prefer if you could give us the older code to reproduce the issue as the bug, as far as I'm concerned, it that the tool gives an inadequate error that is not helpful. 

IOW that should be fixed so other people won't run into the same issue (or at least gets something useful if they do).

Comment 5 Sebastien Pouliot 2013-08-15 16:35:19 UTC
I could not reproduce your error. OTOH I had to make my own PTSTATUS definition, so it's possible it could be related to this. Could you share your StructsAndEnums.cs file ?

Also can you give me the exact version you're using ?

The easiest way to get exact version information is to use the "Xamarin Studio" menu, "About Xamarin Studio" item, "Show Details" button and copy/paste the version informations (you can use the "Copy Information" button).
Comment 6 Claudiu T 2013-08-15 22:33:04 UTC
I'll start with the version info:

Next, the build error. I'm able to reproduce the error, which I found is related to the BaseType attribute for the BrotherPrinterTouchNetwork interface. If the Events and Delegates arguments are not having the same length, the error occurs:

[BaseType (typeof (NSObject), Name = "BRPtouchNetwork",
       Delegates = new string[] {"WeakDelegate"},
		Events = new Type [] { typeof (BrotherPrintTouchNetworkDelegate), typeof(NSNetServiceBrowserDelegate) })]
	public partial interface BrotherPrinterTouchNetwork {
...
}

I've removed the extra typeof(NSNetServiceBrowserDelegate) and everything built successfully. This was something I overlooked last night when I first did write the code, but noticed it later on.

I honestly don't think this is related to the PTSTATUS definition. Anyways, I'm including below the content of my StructsAndEnum.cs file:

Comment 7 Sebastien Pouliot 2013-08-28 09:42:24 UTC
Fixed in maccore e7a4d3e27c724fb64064cc1d3af0553aebda9eea

StructsAndEnum.cs was not needed. Another issue (fixed now) made the exception not displayed on the console.

I added a check for matching the Delegates and Events so a more useful message will be shown in the future. E.g.

> error BI1023: btouch: The number of events and delegates must match for `BRPTouch.BrotherPrinterTouchNetwork`

Thanks for your help.
