Guidelines and HOWTOs/Build from source/edk

edk is a Python script that can be used to easily build KDE projects. Once edk is properly installed and configured, building any KDE project is as easy as invoking edk from the git root of the project.


You may be interested in edk if:

  • You are a new contributor looking for a simple development environment
  • You are a new contributor and you want to build just one application
  • You want to build KDE projects on top of an existing Plasma environment
  • You want to build KDE projects on top of a third party environment (e.g. Gnome or Unity)
  • You are tired to manually call cmake, make, make test, ...

How does it work?

edk is designed to just build, install and (optionally) "run" your project (as edk is primarily designed for applications with a single executable). You don't need to worry about setting up a development environment (besides installing edk itself).

edk is not a replacement of kdesrc-build. It doesn't download source code and it doesn't resolve dependencies (in fact, edk assumes that all build-dependencies are already satisfied). If you want to build the whole KDE stack, kdesrc-build is still the way to go.


git clone git://anongit.kde.org/scratch/elvisangelaccio/edk.git
# assuming that $HOME/bin is in your $PATH
ln -s $PWD/edk/edk.py $HOME/bin/edk
mkdir ~/.config/edk
cp edk/config.ini.example ~/.config/edk/config.ini
cp edk/env.sh.example ~/config/edk/env.sh
You can replace ~/.config with $XDG_CONFIG_HOME, if you have this variable set


Build a project

From the git root of the project:


The script will perform the following operations:

  • Source whatever environment variables are exported in $XDG_CONFIG_HOME/edk/env.sh
  • Build the CMake-based project found in $(pwd) in a build subdirectory
  • Install the project in $EDK. This variable must be defined in env.sh so that edk can automatically pass the -DCMAKE_INSTALL_PREFIX argument to cmake.
  • Run the project tests (if available)

Run the project

Once the project is built, you can run it with:

 edk -r

This assumes that you have configured the project key in the [global] section of the config file. The value of this key is used as the name of the executable to run, unless you define an executable key in the [project] section.

If you don't have the project key (or if you want to override it), you can use as alternative:

 edk -p foo -r

If you want to pass arguments to the project:

 edk -r --foo --bar=XXX

Debug the project

Similarly to the -r option, it's also possible to run the project with a debugger (only gdb for now):

 edk -d

This will execute gdb <executable>.

The -r and -d options are mutually exclusive.

Clean build

 edk -c

This will delete the build directory before performing a new build.


Build with Ninja

Add -GNinja in the cmake-options of your config.ini file (either in the [global] section on in a project-specific section).
