Hello everyone,

I'm new here, and want to setup the development requirement ... however, I have a problem which I don't understand fully.

When I start ./kdesrcbuild (System: Kubuntu 18) , the build stops
"""

In the kcoreaddons log, the following message appears:

CMake Error at CMakeLists.txt:32 (find_package):
Could not find a configuration file for package "Qt5" that is compatible
with requested version "5.12.0".

The following configuration files were considered but not accepted:

/usr/lib/x86_64-linux-gnu/cmake/Qt5/Qt5Config.cmake, version: 5.9.5


My Qmake version is
QMake version 3.1
Using Qt version 5.12.9

I don't understand " Could not find a configuration file for package "Qt5" that is compatible
with requested version "5.12.0"."
Any suggestion what to do that the kcoreaaddons build correctly?

Thank you for your time!

Hello!

The easiest* would be to set up a Kubuntu 20.04 which ships a more recent version of Qt . But using Kubuntu for building KDE is a long way, as I just tried it myself ending up in compiling Qt5.15.1 myself and installing all available headers and libraries, just to get an Okular with the latest Poppler-library running. The basic headers could be found here: https://community.kde.org/Guidelines_and_HOWTOs/Build_from_source/Install_the_dependencies


*: Well, the easiest would be to use ArchLinux
