With the Qt6.4 release last month and the ongoing porting of most KDE Frameworks and Applications to Qt6, it’s time to write a post about how to build KDE applications on Qt6. This guide is intended for developers who want to port their own applications build on KDE frameworks.

The dependencies of a package can be viewed as a directed graph. It does not have to be a tree, as sub-dependencies can be shared. However, it is important to ensure that there are no circular dependencies. Circular dependencies can cause dynamic library builds to fail, and in the worst case, there are cyclic references in your project. Introducing memory leak in reference counting based garbage collectors.
