    Did you try "export LD_LIBRARY_PATH=/yourQTlibpath/" ?

      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)

      cross compiler

      CROSS_COMPILE = arm-linux-gnueabihf-

          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

          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 ?

                  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

                  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 ?

                        Yeah, Im sure. I created the make file for application using qmake of the qt5.2 crosscompiled.

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