Configuring Qt creator for KDE applications

Question

I want to build some KDE applications. Here's what I did so far:

1. sudo apt-get install kde-full
2. add LIBS += -lkdeui in the .pro file of a project which used KDE libraries.

I am using the QtCreator and the above mentioned steps don't seem to be enough. Error message: KApplication: no such file or directory.

What are the steps to configure my system for KDE application development?

Answer 1

The recommended way to build a KDE project is use CMake, not QMake. I really recommend you this approach because some KDE applications, like plasmoids, can not be build correctly using QMake.

In addition you can use KDevelop, but if you prefer Qt Creator, you can use it with a CMake project without problems.

KApplication.h is typically located in /usr/include/KDE folder. Make sure you have it in your include path (i.e. INCLUDEPATH += /usr/include/KDE).
