My windows program use OpenGL, it runs fine in Mac OS X 10.6.x, but failed to
run in Mac OS X 10.7.

My windows program code fragment is :

-----------------------------------------------
 PIXELFORMATDESCRIPTOR pfd =
 {
  sizeof(PIXELFORMATDESCRIPTOR),
   1,
   PFD_DRAW_TO_WINDOW | /*PFD_DOUBLEBUFFER |*/ PFD_SUPPORT_OPENGL,
   PFD_TYPE_RGBA,
   24,
   0,0,0,0,0,0,
   0,0,0,0,0,0,0,
   32,
   0,0,
   PFD_MAIN_PLANE,
   0,
   0,0,0,
 };

 int wglPixelFormat = ::ChoosePixelFormat(m_hDC, &pfd);
 BOOL bSuccess = ::SetPixelFormat(m_hDC, wglPixelFormat, &pfd);
---------------------------------------------

the function SetPixelFormat() doesn't return, the process dead blocked.

I dig into wine source, it is block in the following function call :
pglXCreateGLXPixmap(display, vis, parent);
