How to add qt libraries to embedded board.

[Sung Sean]

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

[Vijaykumar Ponugoti]

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

Do you have libpng for ARM ?

[Vijaykumar Ponugoti]

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.

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 ?

[Vijaykumar Ponugoti]

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".

Hi Gaist,
Did you get any idea? what could be the probelm?
Plz help me.

[SGaist]

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

[Vijaykumar Ponugoti]

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