Hi, I'm starting programming with Xlib and I tried to compile a simple
program which came with a tutorial:

// program: prog-1.cc
#include <X11/Xlib.h>
#include <assert.h>
#include <unistd.h>
#define NIL (0)       // A name for the void pointer
main()
{
      Display *dpy = XOpenDisplay(NIL);
      assert(dpy);
      Window w = XCreateWindow(dpy, DefaultRootWindow(dpy), 0, 0, 
			       200, 100, 0, 
			       CopyFromParent, CopyFromParent,
CopyFromParent,
			       NIL, 0);
      XMapWindow(dpy, w);
      XFlush(dpy);
      sleep(10);
}

I compiled:

gcc -o prog-1 prog-1.cc -lX11 -L/usr/X11/lib

but when I ran:

~/./prog-1
    0       0 [main] C:\usr\local\xlib-tutorial\prog-1.exe 1054

    0   16529 [main] prog-1 1054 handle_exceptions: Dumping stack trace to

here goes the prog-1.exe.core:

Do you have any idea about this ?
Oh yeah, I'm using cygwin-b20.1 and X11R6.4 libraries.

Thank you.
