LD_DEBUG=all cat

After cross compilng Qt creator executable , i try to execute on Grayhill 270 ARM board. The problem while executing is ,

1. if i run my application like "./myApp -qws" there is no error but application not displaying anything on the board
2. If i run my application without QWS like "./MyApp -platform eglfs " it is giving the error like "QWSSocket::connectToLocalFile could not connect:: Connection refused"
3. If i go to Help-->About Qt Creator , a pop up comes like " Qt Creator 3.4.2 (opensource) Based on Qt 5.5.0 (GCC 4.9.1 20140922 (Red Hat 4.9.1-10), 64 bit) " . Is this Qt5 or Qt3
4. After running the application like "./MyApp -platform eglfs " , i run LD_DEBUG=all cat now a list of lines coming like "file=libc.so.6 [0]; needed by cat [0] find library=libc.so.6 [0]; searching" . Is this lists releted to the application "./MyApp -platform eglfs"

That is a contradition. The executable for Qt Creator is called qtcreator, not "myApp"
So either you are launching the wrong example or you are not cross compiling Qt Creator.

Well, is your application executable called "cat"?
Then yes, this is relevant. If not, then obviously no.

1) i tried like LD_DEBUG=all ./myApp
where "myApp" is the name of the executable. now some lines are continuously coming but related to QT executable only. Can i track what is the problem exactly using this lines

2) At the end of debug i found like "symbol=_ZN15QAbstractSocket5errorENS_11SocketErro rE;" . What is this ? how to resolve this?
