OpenGLGraphicsContext(const Size& size,HDC hdc);
virtual ~OpenGLGraphicsContext();

// path primitive

Such things tend to happen when you try to use Win32-specific code on Linux.
Look here.

if u know how to write simple onengl code without X windows then please post here.
And any one know how to initialize opengl function??

Define «without».
What GUI toolkit do you want to use? Is it GTK+ or Qt?
Is there any graphic environment at all? If no, then use OpenGL ES over DRI.
