=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.
=================================================================

My code is:

using OpenTK;
using OpenTK.Graphics;
 
namespace OpenGL4
{
     public class App
    { 
        public static void Main()
        {
			var wnd=new GameWindow(800, 600, new GraphicsMode( ), "OpenGL4", GameWindowFlags.Default,DisplayDevice.Default,4,0,OpenTK.Graphics.GraphicsContextFlags.Default);
			wnd.Run();
        }
    }
}

Same code with version 3.3 in constructor arguments works fine.

My system is:

Ubuntu 10.04
Catalist 10.6 drivers
opentk-1.0-rc1 (and svn version so, both debug and release variants)
Mono 2.6.3 (and 2.4 so)
Radeon 5450
Phenom X3

fglrxinfo output is:

display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Radeon HD 5400 Series
OpenGL version string: 4.0.9901 Compatibility Profile Context

Is this a driver bug? I do something wrong?

Thanks!

Update: this error doesn't depend on opentk and mono version

Update:
Following C program works good on my system:

#include "GL/glus.h"
int main(int argc, char* argv[])
{
	glusPrepareContext(4, 0 , GLUS_FORWARD_COMPATIBLE_BIT);
	glusCreateWindow("Example Window", 800, 600, GLUS_FALSE);
	glusRun();
	return 0;
}

There is a similar issue reported here: http://www.opentk.com/node/1884#new

Can you please try compiling and running your project in release mode? (outside of monodevelop) Does it still crash?

Not sure I understand what do you mean saying

Quote:

I try folowing commands

gmcs -debug- -r:/media/Data/PROJECTS/OpenTK/1.0/Binaries/OpenTK/Release/OpenTK.dll Main
mono Main.exe

The result is same.

Thanks for testing. I'll update my drivers to 10.6 and try to reproduce.
