<![CDATA[Why all the graphics libraries included for a console app]]>I used the fortune server example to create my first app, then removed all aspects of the gui. It's a console only app now.

However, using ldd I see that my compiled app still depends on lots of libX11 etc. libraries (see below). Why? Is this left over from the fortune example - and if so how do I get rid of them?

CONFIG -=app_bundle
QT -=gui

and once I added those to my .pro it now looks right. Thanks!

Take a look "here":http://qt-project.org/doc/qt-5.0/qtdoc/qmake-reference.html to find out about other qmake options available.

Anyway, the easiest way is to create an empty console app and take a look at the generated config.

My Code is too big to post now...but are there other things I can look for?

Probably you are still using "QApplication" header instead of "QCoreApplication".

Maybe you can post your code here
