Craft is an open source meta-build system and package manager. It manages dependencies and builds libraries and applications from source on Windows, Mac, Linux, FreeBSD and Android.

Setting up Craft

Start crafting on Windows

Start crafting on Linux

Start crafting on macOS

Start crafting on FreeBSD

Start crafting on Android

Common Craft commands

Searching for a package

craft --search packagename

Installing a package and its dependencies

craft packagename

Note that installing prebuilt packages (libraries and some apps which are common dependencies of others) won't immediately generate their source directories. If you need them, see Installing a prebuilt package.

Uninstalling a package

craft --unmerge packagename

Updating a package

craft -i packagename

Updating Craft itself

craft -i craft

Updating Craft's KDE blueprints

craft -i craft-blueprints-kde

Updating all installed packages

craft --upgrade

Changing to the source directory of a package

cs packagename

Changing to the build directory of a package

cb packagename

Compiling a package

To compile and install a package for testing after modifying its source code, run

craft --compile --install --qmerge packagename

Creating an installer

To create a MacOS .dmg bundle, Windows .exe installer or Linux .AppImage for a package, run

craft --package packagename

When packaging for Windows, the PackageType option in CraftSettings.ini controls the type of installer created. Read the comments above it for more information.

If the package's source code has been modified, don't forget to compile and install it before creating a new installer.

Installing a prebuilt package

Libraries and certain apps which are common dependencies of other packages (such as Kate) will be pulled as prebuilt binaries from the "cache" stored on and built by KDE's servers, instead of their sources being cloned and built on your system. This is done to shorten compile times. The --no-cache option overrides this behavior, in case modifying the sources of prebuilt packages is necessary:

craft -i --no-cache packagename

Adding new blueprints

If you want to build a new application using Craft, you'll need a blueprint for it and all its dependencies first. Learn more about writing blueprints at Craft/Blueprints.

Advanced tips

Hard-code versions of packages

For non-prebuilt packages, the last release compatible with your environment is built by default. To build a non-default version, run

craft --set version=versionname packagename

Replace versionname with the desired branch name (like master) or a specific version number (like 0.57.0).

The version can also be set for an entire category, for example, for the KDE Frameworks, run

craft --set version=versionname kde/frameworks

Alternatively, you may also edit BlueprintSettings.ini:

[category/packagename]
version = versionname

Using Craft with an IDE

Using Craft with Qt Creator

To compile packages from within Qt Creator, we'll need to start it from a shell with the Craft environment set up:

$ source CraftRoot/craft/craftenv.sh
$ qtcreator

Now fire up another shell with the Craft environment set up as well. If you haven't already, install the package you want to work on. Now change to its source directory and take note of the path you've been switched to.

Back in Qt Creator, press Ctrl+O to open a project, and navigate to the aforementioned source directory. Inside of it, select the CMakeLists.txt file. Ensure you're looking at the Projects tab by pressing Ctrl+5 and make sure only the kit ending in in PATH (CraftRoot) is selected, then press the Configure Project button and let Qt Creator finish importing everything.

You can now try to start a build to see if everything went well!

Using Craft with VS Code

Note that this example demonstrates working on KDEConnect, but the same instructions should apply to other packages as well.

To use the debugging capabilities of VS Code, we will create a .code-workspace file and update it according to our use case. Create kde.code-workspace and paste one of the following example workspace configurations into it:

Windows development

Linux development

Now edit it according to your setup. Additional information can be found at https://code.visualstudio.com/docs/editor/workspaces.

Debugging a standalone app with symbols

Craft uses the RelWithDebInfo build type by default. As such, every library and executable is compiled with the release symbols stripped from its main file and saved separately in a corresponding .pdb file on Windows or .dSYM package on MacOS.

These symbols will not be included in the final redistributable package generated by Craft using the --package option, however, if PackageDebugSymbols is enabled in CraftSettings.ini, a separate archive will be created containing all the debug symbols.

If an issue you're trying to debug is specific to the packaged app only, you can use Qt Creator's Start and Debug External Application option to run the packaged app and automatically attach to it.

Example for packaged MacOS apps:

In Local Executable, provide a path to the executable file inside the .app container, such as /Volumes/External/CraftRoot/build/extragear/kmymoney/archive/Applications/KDE/kmymoney.app/Contents/MacOS/kmymoney
In Debug information provide a path to the folder containing the debug symbols package (kmymoney.app.dSYM) generated by Craft, such as /Volumes/External/CraftRoot/build/extragear/kmymoney/image-RelWithDebInfo-master/Applications/KDE
Check Break at main if this is your initial setup to make sure everything works as expected
Optionally add the Source Paths Mapping under Preferences -> Debugger if your local source code location doesn't match the one used to generate the package being debugged, resulting in the main() break showing disassembled code.

Troubleshooting

If a package fails to build, you'll probably be greeted with something similar to:

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 for errors, or have a look at the log file located in $HOME/.craft on MacOS/Linux and %USERPROFILE%\.craft on Windows, which should contain more details. You can additionally grep this file for the phrase error, narrowing down your search.

-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.
