    can i use openGl ES 1 instad of openGl ES 2

    I want to use openGl ES 1 instead of openGl ES 2 and i have made below changes in .pro file

    .pro
    Code:
    QT += opengl
    
    DEFINES +=  QT_OPENGL_ES_1  \
                GL_GLEXT_PROTOTYPES
    
    LIBS +=  -llibGLESv1_cm
    when i call glGetString(GL_VERSION) it give OpenGL ES 2.0 .

    I want to use openGl ES 1.

    And does N8 and E7 support openGL ES 1

    Take a look at this game example:

    https://projects.forum.nokia.com/eponggame

    It uses GLES2 but just change the EGL initialization code to support GLES1 from QtGameEngine.cpp file and link to correct GLES1 libraries in qtepong.pro file.

    .pro should contain: (at least for me, Linux-64bit Qt-SDK 4.7.4-32bit )
    DEFINES += USE_GLES11
    DEFINES += QT_OPENGL_ES_1
    LIBS += -llibGLESv1_CM
