qws parameter for Qt-embedded is not working

Question

I created a basic Qt application for Qt-embedded but when I executed that application in my target platform using the -qws parameter then an error message always appear, please see below,

#./test_app -qws
QWSSocket::connectToLocalFile could not connect:: Connection refused QWSSocket::connectToLocalFile could not connect:: Connection refused QWSSocket::connectToLocalFile could not connect:: Connection refused QWSSocket::connectToLocalFile could not connect:: Connection refused QWSSocket::connectToLocalFile could not connect:: Connection refused QWSSocket::connectToLocalFile could not connect:: Connection refused
No Qt for Embedded Linux server appears to be running. If you want to run this program as a server, add the "-qws" command-line option. terminate called without an active exception Aborted

Please advice.

Thanks.

Answer 1

• Is "test_app" linked again qt/embedded?
• What print "strace ./test_app"
• Have you played with LD_DEBUG-environmnt variable?
