[Mono-osx] Beginner - Very Simple P/Invoke Example?

[cannyshammy]

Hi, 

Im new to Mono development tho I have done a fair bit of XNA stuff. For this
current project however I need to catch system-wide input events so I need
some native code for that.

Im trying to get a very simple P/Invoke example working on OSX. My C looks
like:

#include <stdio.h>

void myMethod( int x )
{
    printf("my method called: %d\n",x);
}

Which compiles to libXCodeMono.dylib

I have then copied that to my mono project bin dir and tried to use it with
the following code:

using System;
using System.Runtime.InteropServices;

namespace SimpleMacMonoHook
{
	public class MacHook
	{
		[DllImport("libXCodeMono")]
                static extern int myMethod (int x);
		
		public MacHook ()
		{
			myMethod(99);
		}
	}
}

But it throws me the following error:

Unhandled Exception: System.DllNotFoundException: libXCodeMono.dylib
  at (wrapper managed-to-native) SimpleMacMonoHook.MacHook:myMethod (int)
  at SimpleMacMonoHook.MacHook..ctor () [0x00006] in
/Volumes/SHARED/Dropbox/Projects/Personal/Live/Inputtie/Mono/SimpleMacMonoHook/SimpleMacMonoHook/MacHook.cs:25 
  at SimpleMacMonoHook.MainClass.Main (System.String[] args) [0x00000] in
/Volumes/SHARED/Dropbox/Projects/Personal/Live/Inputtie/Mono/SimpleMacMonoHook/SimpleMacMonoHook/Main.cs:22 

I have attached my project here:

Anyone got any ideas where im going wrong? Even better can anyone point me
in the direction of some good mac pinvoke resources?

Cheers,
Mike
