QT Application on Linaro ubuntu Desktop for ZC702 ARM

[prashantkumar.agrawal]

Hi,
I have created a QT application for ARM architecture by using Xilinx linux arm toolchain.
So If I am checking the file type it is coming as it is built for ARM.
But when I am executing it it is throwing an error as bash: ./App: No such File or Diretory but this file is present in the diretory from where i am executing it.

What i have done on target is-
1) Copied all the libraries and binary for ARM at /opt/Qt-arm__
2) Configured the load path as export LD_LIBRARY_PATH=/opt/Qt-arm/lib

So is there anything I am missing which is preventing me to run the application on the traget board.

did you create it with ARM? if yes, your the things you are suspicious to are irrelevant. But, I don't think so, if you really want to understand where the problem comes from, run qt application and create a new project. build something, see if everything goes fine. (the conditions 1 & 2 you mentioned are properly set). if you receive errors again paste it here.

Hi,
I created with the "ARM" only but the problem was of wrong toolchain as we were using arm-xilinx-linux-gnueabi but the Linaro was not supporting that rather it was supporting arm-linux-gnueabihf.
So that problem is solved and i am getting some different type of issue and not able to fire up the GUI steps i followed are as:

1) qt-everywhere-opensource-src-4.7.3.tar.gz(Extract It)
2) qmake.conf: Replace: arm-none-linux-gnueabi-gcc by arm-linux-gnueabihf-gcc in qt-everywhere-opensource-src-4.7.3/mkspecs/qws/linux-arm-gnueabi-g++/qmake.onf

3) Set the path: export CROSS_COMPILE=arm-linux-gnueabihf- export PATH=/usr/bin:$PATH export ZYNQ_QT_BUILD=/home/user/qt-everywhere-opensource-src-4.7.3 export ZYNQ_QT_INSTALL=/usr/local/Trolltech export PATH=$ZYNQ_QT_INSTALL/bin:$PATH

4) ./configure -embedded armv7l -xplatform qws/linux-arm-gnueabi-g++ -little-endian -opensource -host-little-endian -confirm-license -prefix $ZYNQ_QT_INSTALL -qt-zlib -qt-libtiff -qt-libpng -qt-libmng -qt-libjpeg -no-openssl -no-nis -no-cups -iconv -no-pch -no-dbus -qt-freetype -no-opengl -qt-gfx-linuxfb -qt-gfx-vnc -qt-gfx-qvfb

5) make make -install copied the libraries to the target board.

6) ./appname -qws -display QVFb:0 error: driver cannot connect Aborted
./appname -qws LinuxFb:mmwidth=1024:mmheight=768 this dsnt give any error but, its not launching the GUI but printing the log messages in terminal.

can you tell What steps are missing here?
