Guidelines and HOWTOs/Build from source/Windows
Craft is a tool to build the sources and its third-party requirements. It is the easy way to build software.
Setting up craft
While Craft is capable of installing a embedded Python version we recommend to install Python yourself. The embedded version is completely sufficient for most packages, some may require a full installation of Python. Download Python 3.6+
Setting up a powershell
Powershell is required to be at least version 5.0. If your running Windows 10 you most probably won't need to update Powershell.
You can check the version with $PSVersionTable.PSVersion .
Setting up a compiler
Currently Craft supports both the MinGW and Microsoft Visual Studio (msvc) compiler. While MinGW can be installed by Craft, Visual Studio must be installed independently by the user.
Direct X SDK
If you are using the MinGW compiler, in order to compile the Qt5 qtbase package you will also need to install the Microsoft DirectX SDK. Make sure to open a new command line window after the installation for the environment variables to be set.
- Start a powershell environment.
- Allow execution of powershell scripts.
Set-ExecutionPolicy -Scope CurrentUser RemoteSigned
- Install Craft and folow the instructions

To use Craft you need to start a Powershell window, point that to KDEROOT\craft and run the initalization script. For example:
This tells Craft about your environment settings (e.g. paths). It will load your configuration from KDEROOT\etc\kdesettings.ini. If there are any error messages Craft will not work as expected. The output should look similar to this one (of course with your paths):
PS C:\kderoot\craft>.\kdeenv.ps1 KDEROOT : C:\kderoot\ KDECOMPILER : msvc2015 KDESVNDIR : C:\kderoot\download\svn KDEGITDIR : C:\kderoot\download\git DOWNLOADDIR : C:\kderoot\download PYTHONPATH : C:\kderoot\python PS C:\kderoot\>
Common Craft commands
- Installing a package and its dependencies: Simply run
- Updating an installed package: Once you have packagename built, type to update packagename.
craft -i packagename
- Updating Craft:
To build a non default version, append a line to kderoot/etc/kdesettings.ini of form:
category/packagename = branch
For example, to install master branch of kdevelop, the line to be appended should look like:
extragear/kdevelop = master
To find the category of the package you want to install, run this in powershell:
craft --search packagename
The second line of the output will be of form: category/packagename
If a package fails to build, you'll be greeted with something like:
... craft warning: while running make cmd: jom craft warning: Action: compile for libs/qt5/qtbase FAILED *** Craft all failed: all of libs/qtbase failed after 0:07:25 *** craft error: fatal error: package libs/qtbase all failed
In order to figure out what failed, grep the command line output above for errors.
Or have a look at the log file located in %USERPROFILE%\.craft which will contain much more details.
Search for "error", or "error:" in the file.
