* '''Updating an installed package''': Once you have ''packagename'' built, type <syntaxhighlight lang="text">craft -i packagename</syntaxhighlight> to update <tt>packagename</tt>.

    ## The version of Qt.
    Version = 5.9
    ## The compiler version, if you are not sure what to use, have a look at the directory set in QtSDK/Path.

== Troubleshooting ==
== Using Craft ==
 
To use Craft you need to start a Powershell window, point that to <tt>KDEROOT\craft </tt> and run the initalization script. For example:
If a package fails to build, you'll be greeted with something like:


  ...
C:\CraftRoot\craft\craftenv.ps1
  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.
This tells Craft about your environment settings (e.g. paths). It will load your configuration from <tt>CraftRoot\etc\CraftSettings.ini</tt>. 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):


Or have a look at the log file located in <tt> %USERPROFILE%\.craft</tt> which will contain much more details.
PS C:\CraftRoot\craft>.\craftenv.ps1
Craft              : C:\CraftRoot
Version            : master

Craft is a tool to build the sources and its third-party requirements. It is the easy way to build software.

Setting up craft

Installing python

While Craft is capable of installing an embedded Python version sufficient for most packages, we recommend a full installation of Python. The current version is 3.7. Download Python 3.6+

Setting up a powershell

Powershell is required to be at least version 5.0. If you're running Windows 10 you most probably won't need to update Powershell.

You can check the version by invocating $PSVersionTable.PSVersion in a Powershell terminal.

In case you need a newer one, we recommend Powershell Core.

The latest version of the standard powershell can be found here.

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 (only for MinGW setups)

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.

(Optional) Enable development mode

Windows 10 supports the creation of symbolic links, but only if the development mode is activated. Allowing symbolic links allows faster (much faster) extraction of archives. Enable development mode

Installing Craft

  1. Start a PowerShell environment (Do not use PowerShell ISE, it doesn't work very well with python). It might be required to run it as administrator.
  2. Allow execution of powershell scripts by executing the following command:
    Set-ExecutionPolicy -Scope CurrentUser RemoteSigned
  3. Install Craft and follow the instructions by executing the following command:
    iex ((new-object net.webclient).DownloadString('https://raw.githubusercontent.com/KDE/craft/master/setup/install_craft.ps1'))
  4. Consider adding exception for the entire craft root directory to your antivirus' exceptions, otherwise build of some packages can fail (example: build of kde/frameworks/tier2/kdoctools when AVG is used).


Note: For Microsoft Visual Studio compiler, it's necessary to have VCTOOLSREDISTDIR environment variable pointing to: "C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Redist\MSVC\xx.xx.xxxxx" for MSVS 2017 and VCINSTALLDIR environment pointing to "C:\Program Files (x86)\Microsoft Visual Studio\2015\Community\VC\" for MSVS 2015.

Using the stock Qt SDK

This will skip all Qt packages and use the official Qt builds instead. It will work fine for most CMake based recipes but definitely cause problems with QMake based projects. You will of course also miss all patches we usually apply to Qt. This is only recommended when you know what you are doing and you won't get support for in our channel.

To activate the SDK mode adapt the [QtSDK] section in your etc/kdesettings.ini to something like:

   [QtSDK]
   ## Whether to use prebuild Qt binaries.
   Enabled = True
   ## The path to the Qt sdk.
   Path = C:\Qt
   ## The version of Qt.
   Version = 5.9
   ## The compiler version, if you are not sure what to use, have a look at the directory set in QtSDK/Path.
   ## The compiler must be of the same type as General/KDECOMPILER.
   ## If you are using mingw please make sure you have installed the mingw using the Qt installer.
   Compiler = msvc2017_64

Using Craft

To use Craft you need to start a Powershell window, point that to KDEROOT\craft and run the initalization script. For example:

C:\CraftRoot\craft\craftenv.ps1

This tells Craft about your environment settings (e.g. paths). It will load your configuration from CraftRoot\etc\CraftSettings.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:\CraftRoot\craft>.\craftenv.ps1
Craft               : C:\CraftRoot
Version             : master
ABI                 : windows-msvc2017_64-cl
Download directory  : C:\CraftRoot\download

Then start crafting
