    Hi,
    Thank you for the support. I have cross compiled Qt4.8.4 and its working on my board.
    Now I am trying to cross compile Qt 5.2. I need few other options to get enabled so I am working on Qt 5.2. But Im getting the following error.
    My qmake.conf file is

    qmake configuration for building with linux-omap5-g++

    MAKEFILE_GENERATOR = UNIX
    CONFIG += incremental gdb_dwarf_index
    QMAKE_INCREMENTAL_STYLE = sublib

    include(../common/linux.conf)
    include(../common/gcc-base-unix.conf)
    include(../common/g++-unix.conf)

        Hi SGaist ,
        Thanks for the reply. As you said I have installed libpng and zlib for arm (in my toolchain folder). Now I am able to do configure, make and make install on Qt5.2. But I am still facing problems.
        I have copied all the installed libraries on to my board and when I tried to run application I am facing the following problem.
        **root@dra7xx-evm:~# ./Wid1
        QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv_open failed
        QIconvCodec::convertToUnicode: using Latin-1 for conversion, iconv_open failed
        This application failed to start because it could not find or load the Qt platform plugin "xcb".

        Available platform plugins are: eglfs, kms, linuxfb, minimal, minimalegl, offscreen.

        Reinstalling the application may fix this problem.
        Aborted
        root@dra7xx-evm:~# ./Wid1 -platform kms
        QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv_open failed

        root@dra7xx-evm:~# **

        And I observed that when I gave make install in qt5.2 the log contains some errors as followed(sample of Log).

              I didn't doubt that you had them (otherwise you wouldn't have been able to cross-compile at all) However can you confirm that "~/CC/gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux/bin" is in your PATH environment variable ?

                medha@C528:~$ export PATH=$PATH:/home/medha/CC/gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux/bin

                Actually, If something went wrong how the libraries are being created.? And when I gave "file" command on any of the created library file, it informs that the library is cross compiled for arm.
                And I tried copying the created libraries onto the filesystem and run some Qt application as follows, after setting the LD_LIBRARY_PATH variable.
                But I am getting problem.
                On the target

                root@dra7xx-evm:~# ./Wid1
                QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv_open failed
                QIconvCodec::convertToUnicode: using Latin-1 for conversion, iconv_open failed
                This application failed to start because it could not find or load the Qt platform plugin "xcb".

                Available platform plugins are: eglfs, kms, linuxfb, minimal, minimalegl, offscreen.

                Reinstalling the application may fix this problem.
                Aborted
                root@dra7xx-evm:~# ./Wid1 -platform kms
                QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv_open failed

                QSocketNotifier: Can only be used with threads started with QThread
                root@dra7xx-evm:~#

                What could be the problem? Am I running the application properly?
                Please help me.

                    Are you sure that you are using the same Qt on your target than the one you cross-compiled ?

                        Cross-compiling is one thing, how did you install Qt on your board ?
