View Full Version : [SOLVED] Ubuntu 11.10: Qt Creator can't locate QApplication header and include it

October 22nd, 2011, 01:17 PM

I am trying to start developing QT applications on Ubuntu 11.10, and I downloaded and installed Qt Creator (v 2.2.1, based on Qt 4.7.3) from the Software Center.

The following add-ons were also installed: gdb, qt4-demos, qt4-dev-tools, qt4-doc, qt4-qmlviewer and qtcreator-doc.

I try creating a new project in Qt Creator like this:

Create project...->Other Project->Qt Console Application

In the main.cpp that is created, however, if I try to include simple headers like:

#include <QApplication>then the Qt Creator complains about:

QApplication: No such file or directoryI can include headers like this one though:

#include <QtCore/QCoreApplication>Under Tools->Options->Qt4, I can see that the path to qmake-qt4 is auto-detected and set as:


What am I missing in order to get Qt Creator to find QApplication header?

Thanks in advance.

Kind Regards,

Please ignore the question above; I choose Qt Gui Application when creating a new project instead, and everything is fine.

I consider this issue solved.
