Hi.
I'm not sure if this error must be reported here, or in Mono-list.
I try to debug an openGL application, using OpenTK or using Tao, in both
the debug fails and crashes.
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.
