    Question "applet not found" error when trying to run an application created with QTembedded

    Hi,

    I am working on a sbc6000x board (at91sam9261 micro and linux 2.6.24) and i am trying to crosscompile application for this board from my pc (ubuntu 14.14).
    When i try to run the application (after copying it in /bin and chmod 755 it) i have an error "applet not found". The applicaion is a qt widget application, a push button with a msgbox.

    To help understand this error i will explain what i did to have this application.

    I am using :
    qt-everywhere-opensource-src-4.8.5 ou autre source
    gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux
    tslib-1.0 (because i need to use the touch screen and when trying to configure qt with -qt-mouse-tslib i need the lib and inclue of tslib).

    Configuration and installation of tslib

    Qt Code: 
    1. cd /home/spi/installQt/tslib-1.0/tslib-1.0/
    2. chmod a+x autogen.sh
    3. ./autogen.sh
    4. ./configure CC=/home/spi/installQt/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/bin/arm-linux-gnueabihf-gcc CXX=/home/spi/installQt/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/bin/arm-linux-gnueabihf-g++ --prefix=/home/spi/installQt/tslib-arm --host=arm-linux-gnueabihf --enable-shared=yes --enable-static=yes
    To copy to clipboard, switch view to plain text mode 

    I comment the line #define malloc rpl_malloc in the file config.h or i will have an error in the make

    Qt Code: 
    1. make
    2. make install
    To copy to clipboard, switch view to plain text mode 

    No error at this point.

    Configuration and installation fo QTembedded

    First i modify the qmake.conf file to respect the path of my compiler and to put the include/lib of tslib :

    Qt Code: 
    1. #
    2. # qmake configuration for building with arm-none-linux-gnueabi-g++
    3. #
    4.  
    5. include(../../common/linux.conf)
    6. include(../../common/gcc-base-unix.conf)
    7. include(../../common/g++-unix.conf)
    8. include(../../common/qws.conf)
    9.  
    10. # modifications to g++.conf
    11. QMAKE_CC = /home/spi/installQt/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/bin/arm-linux-gnueabihf-gcc
    12. QMAKE_CXX = /home/spi/installQt/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/bin/arm-linux-gnueabihf-g++
    13. QMAKE_LINK = /home/spi/installQt/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/bin/arm-linux-gnueabihf-g++
    14. QMAKE_LINK_SHLIB = /home/spi/installQt/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/bin/arm-linux-gnueabihf-g++
    15.  
    16. # modifications to linux.conf
    17. QMAKE_AR = /home/spi/installQt/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/bin/arm-linux-gnueabihf-ar cqs
    18. QMAKE_OBJCOPY = /home/spi/installQt/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/bin/arm-linux-gnueabihf-objcopy
    19. QMAKE_STRIP = /home/spi/installQt/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/bin/arm-linux-gnueabihf-strip
    20. QMAKE_INCDIR += /home/spi/installQt/tslib-arm/include
    21. QMAKE_LIBDIR += /home/spi/installQt/tslib-arm/lib 
    22.  
    23. load(qt_config)
    To copy to clipboard, switch view to plain text mode 

    Then i configure QT :

    Qt Code: 
    1. cd /home/spi/installQt/qt-everywhere-opensource-src-4.8.5/
    2. ./configure -opensource -confirm-license -prefix /usr/local/Qt-4.8.5-arm-linux -embedded arm -little-endian -no-pch -xplatform qws/linux-arm-gnueabi-g++ -qt-mouse-tslib -no-webkit -no-qt3support -no-cups -no-largefile -optimized-qmake -no-openssl -nomake tools -static
    To copy to clipboard, switch view to plain text mode 

    I use -qt-mouse-tslib because i want to use the touch screen and i use -static because i read that (even if the application would be heavier and less "flexible) i would only have to transfert and executable and not "care" about libraries or other dependencies.

    Qt Code: 
    1. make
    2. sudo make install
    To copy to clipboard, switch view to plain text mode 

    Still no error.

    Configuration in QT creator

    I create a kit with the qmake and the compiler which are in the paths :
    Qt Code: 
    1. /usr/local/Qt-4.8.5-arm-linux/bin/
    To copy to clipboard, switch view to plain text mode 
    and
    Qt Code: 
    1. /home/spi/installQt/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/bin/arm-linux-gnueabihf-g++
    To copy to clipboard, switch view to plain text mode 

    In my project i add this argument to the make :
    Qt Code: 
    1. ARCH=arm CROSS_COMPILE=/home/spi/installQt/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/bin/arm-linux-gnueabihf-
    To copy to clipboard, switch view to plain text mode 

    On the target i add this to the environment :
    Qt Code: 
    1. export QWS_MOUSE_PROTO=tslib:/usr/input/ts
    2. export QWS_DISPLAY=LinuxFB:mmWidth=480:mmHeight=272
    To copy to clipboard, switch view to plain text mode 

    I feel i must not be far from having something running but i am now stuck on this.
    Thank you for your future answers or advices !

    EDIT 1 : After some research i added "CONFIG += static" to my .pro file. It changed nothing.
