Cannot run application - Qt5 - Linux Embedded - QIconvCodec::convertToUnicode: using Latin-1 for conversion, iconv_open failed, Illegal instruction

[perez.sgo]

Hi,

i'm trying to run a demo application to check if my Qt5's configuration and installation is ok, but cannot figure out the problem. The output it's always the same:
@QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv_open failed
QIconvCodec::convertToUnicode: using Latin-1 for conversion, iconv_open failed
Illegal instruction@
I run the application with the following script:
@#!/bin/sh
appname=basename $0 | sed s,\.sh$,,

dirname=dirname $0
tmp="${dirname#?}"

if [ "${dirname%$tmp}" != "/" ]; then
dirname=$PWD/$dirname
fi
LD_LIBRARY_PATH=$dirname
export LD_LIBRARY_PATH
$dirname/$appname "$@"@

The libraries files are copied to the folder where the compiled program is. I cannot run it without the script, because otherwise it cannot find the libraries:
@./analogclock: error while loading shared libraries: libGLESv2.so: cannot open shared object file: No such file or directory@
The demo i'm trying to run is analogclock. Also tried another ones, with no succes.

Any help please?. Thanks in advance,

Santiago

Adding the QT_DEBUG_PLUGINS=1 flag, the output while executing the program is:
@QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv_open failed
QIconvCodec::convertToUnicode: using Latin-1 for conversion, iconv_open failed
QFactoryLoader::QFactoryLoader() checking directory path "/usr/local/Qt5.1.0-ARM-sgo/plugins/platforms" ...
QFactoryLoader::QFactoryLoader() looking at "/usr/local/Qt5.1.0-ARM-sgo/plugins/platforms/libqlinuxfb.so"
Illegal instruction@
