Hi.
I'm not sure if this error must be reported here, also sent this message
to Monodevelop-list.
I try to debug an openGL application, using OpenTK or using Tao, in both
the debug fails and crashes.
I'm not sure if the problem is related to Mono debugger, or Monodevelop.
Here I show when debugging using OpenTK.
This is the little app.
public static void Main (string[] args)
{
MainWindow mainWindow = new MainWindow();
mainWindow.Title = "OpenTK Test !!!";
mainWindow.Run();
}
class MainWindow : GameWindow {
protected override void OnLoad(EventArgs e) {
int a;
a=0;
GL.ClearColor(Color.MidnightBlue);
}
protected override void OnRenderFrame(FrameEventArgs e) {
GL.Clear(ClearBufferMask.ColorBufferBit |
ClearBufferMask.DepthBufferBit);
GL.MatrixMode(MatrixMode.Modelview);
GL.LoadIdentity();
}
GL.Color3(Color.Red);
GL.Begin(BeginMode.Triangles); // Drawing Using
TrianGL.es
GL.Vertex3(0.0f, 0.2f,
0.0f); // Top
GL.Vertex3(-0.2f, -0.2f,
0.0f); // Bottom Left
GL.Vertex3(0.2f, -0.2f,
0.0f); // Bottom Right
GL.End();
SwapBuffers();
}
}
The debug crashes inmediatly, displaying the application trace attached.
However, if I run not debugging, I not set any breakpoing, or in release
mode, the app runs fine.
Here is the trace of application displayed in Monodevelop.
Any help? It's a bug?
Thanks in advance!
Daniel.
