Re: QT4: Single Application without GUI
Message 1 in thread
I'd like to know if anyone's tried to build a subset of Qt4 without
the GUI components, and if there is an easy way to do that. How nice
it would be if there was a -no-gui option to the configure script!

Message 2 in thread
I could be misunderstanding the problem, but I run several single instance
applications with no GUI components. I simply use the QCoreApplication and
a single class. I use a QSetting that tells me if the application is
running or not.
I then drive all the necessary events using QTimers from within the single
class.
I have one Timer that checks to see if there is a "stop" file present. When
the file is present, I delete the "stop" file and exit the application.
(This allows me to turn the application on and off with a script.)
Is this not what you have in mind?

You should be able to use QCoreApplication in the solution.

Thanks, I plan to... I was just saying that in order to build Qt
without gui, I had to edit the src.pro file after doing a configure,
removing the svg and gui references. Which I suppose is no big
deal... but it would be nice if there was a -no-gui option for
configure that would switch off those subdirs before I started
building it.

I don't think youll have a problem with building it with the GUI, and
only using the non-gui portion in your project.

You're assuming I'm building qt in an environment that contains all
the x11 libs and headers. Which I am not.

I completely agree with you. There's no way to turn off GUI components at
configure/build time if you want to just build and install QtCore on an Xl-ess
machine.
I would also love a -no-gui switch...
