QWSSocket::connectToLocalFile could not connect:: Connection refused

[shivcena]

Because "the Q_WS_* macros have been removed" in QT5
when I try to run export QT_QPA_EGLFS_FB=”/dev/fb0″ and try to execute the application like "./test12 -platform eglfs " without giving -qws at the end I get this error:

"QWSSocket::connectToLocalFile could not connect:: Connection refused".

How can I resolve this problem?

Also im having some doubts like,

1. i refered other forums for this same problems and they asked like Have you played with LD_DEBUG-environmnt variable? . what is LD_DEBUG-environmnt variable? how can i configure that?

2. What is eglfs? how to configure/install it. Whether i have to configure/install in qt creator or in target?

3. why the error "QWSSocket::connectToLocalFile could not connect:: Connection refused". is coming. What is the meaning of this error.
