    driver not found is because of I not set envionment variables.

    when I set envionment variables like this :

    export QT_PLUGIN_PATH=/plugins
    export TSLIB_CONSOLEDEVICE=none
    export TSLIB_FBDEVICE=/dev/fb0
    export TSLIB_TSDEVICE=/dev/input/event0
    export TSLIB_CALIBFILE=/etc/pointercal
    export LD_LIBRARY_PATH==/lib:/usr/lib:/usr/local/lib:/usr/local/XSGX/lib
    export set QWS_MOUSE_PROTO="Tslib:/dev/input/event0 intelliMouse:/dev/input/mouse0"

    driver not found error not occur.But new error has appear.

    The error message is :./hellogl_es2: symbol lookup error: /lib/libQtOpenGL.so.4: undefined symbol: _ZN15QGraphicsSystem16createPixmapDataEP11QPixmapData

    So I had search my file system.where is libQtOpenGL.so.4 file .there is only one file named libQtOpenGL.so.4 underside lib folder.

    I am puzzle! This lib is build out of QT. QT configure error? Graphics_SDK build error?

    QT configure is:

    -prefix /home/selfworkdir/filesys_01_06/rfs -opensource -confirm-license -little-endian -host-little-endian -embedded arm -platform qws/linux-x86-g++ -xplatform qws/linux-TIarmv7-sgx-g++ -depths 16,24,32 -no-mmx -no-3dnow -no-sse -no-sse2 -no-glib -no-cups -no-largefile -no-accessibility -no-openssl -no-gtkstyle -qt-mouse-pc -qt-mouse-linuxtp -qt-mouse-linuxinput -plugin-mouse-linuxtp -plugin-mouse-pc -fast -opengl es2 -qt-gfx-transformed -qt-gfx-vnc -qt-gfx-linuxfb -qt-gfx-multiscreen -qt-mouse-tslib -plugin-gfx-powervr -D QT_NO_QWS_CURSOR -D QT_QWS_CLIENTBLIT

    Graphics_SDK_4_05_00_03(build with make BUILD=release OMAPES=6.x SUPPORT_XORG=1 all)

    Someone can help me ! what is wrong?

    Thank you very much!

    The prefix should indicate where Qt should be installed with respect to the target file system. For example, if Qt should be installed under /usr/local on the target the prefix should be "/usr/local". Your prefix seems to be relative to the host. 

    Follow the steps given in the links below to build and install Qt:

    Hi

    finally i might be able to help out myself here !

    i had this symbol lookup error when i was mixing qt 4.6.3 with qt-4.7.5 libs .. then obviously one lib trys to find symbols which might not be in a older version of its dependant lib ..

    maybe try to bring your qt installation in your target on a update and same version level !

    Good luck
