    Default OpenVG EGL supprt in 4.6.0-tp1 + OpenGL questions

    1.
    I was trying to build 4.6.0-tp1(with msvc2005) on WindowsXP with '-openvg' option in configure.exe.
    During the config step it did gave me "openvg support - yes" . But when I ran nmake, it gave error while finding for <EGL/egl.h>. Its obvious from the configure help -
    -openvg ............ Enables OpenVG functionality
    Requires EGL support, typically supplied by an OpenGL
    or other graphics implementation
    What I want to know is,,,how do we enable support for EGL ? do we have to install some libraries ? some installer ? copy some headers ? I havent jumped into opengl yet and dont know much about the configurations. Can someone guide me ?

    2.
    I also have few more questions related to OpenGL...are various OpenGL versions (1.5,2.0,3.x) dependent on hardware ? For example in Boxes example in Qt Demos, I used to get message that OpenGL 1.5 or higher is required. What do we mean by this ? How do we install or enable the higher OpenGL versions ?

    3.
    Also in configure I saw for Windows CE we have option for
    -opengl-es-cm ...... Enable support for OpenGL ES Common
    -opengl-es-cl ...... Enable support for OpenGL ES Common Lite
    -opengl-es-2 ....... Enable support for OpenGL ES 2.0
    Can someone explain these too ?

    FYI : My system is Intel 2.66 GHz with 512 MB RAM...running WindowsXP SP3.

    What happened to '-direct3d' option in 4.6.0-tp1 configure.exe ???
