KDeltaChat is a Delta Chat client using Kirigami framework.


KDeltaChat build depends on libdeltachat, Kirigami framework and several QML modules.


libdeltachat is not packaged for most distributions, so the easiest way is to install it system-wide from the source.

Building libdeltachat requires Rust. Install it from https://rustup.rs/ with

$ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y --default-toolchain none

Then, clone the source, build libdeltachat and install it:

$ git clone https://github.com/deltachat/deltachat-core-rust.git
$ cd deltachat-core-rust
$ cmake -B build . -DCMAKE_INSTALL_PREFIX=/usr
$ cmake --build build
$ sudo cmake --install build


Install QtQuick and required QML modules using your system package manager.


Build time dependencies:

  • qtbase5-dev
  • qtdeclarative5-dev (for /usr/lib/x86_64-linux-gnu/cmake/Qt5Quick/Qt5QuickConfig.cmake)
  • qtwebengine5-dev
  • cmake
  • extra-cmake-modules
  • pkg-config

Runtime dependencies:

  • qml-module-qtquick-controls
  • qml-module-qtquick-controls2
  • qml-module-qtquick-dialogs - used for account import file dialog
  • qml-module-qtquick-layouts
  • qml-module-qtmultimedia
  • qml-module-qtwebengine
  • qt5-image-formats-plugins - WebP support

#Arch Linux

Install Kirigami:

  • kirigami2

Install FileDialog:

  • qt5-quickcontrols

Install extra-cmake-modules(https://api.kde.org/ecm/manual/ecm-kde-modules.7.html):

  • extra-cmake-modules

WebP support:

  • qt5-imageformats

HTML view:

  • qt5-webengine

Media player:

  • qt5-multimedia


OpenSUSE Leap 15.2:

# Install Rust core dependencies
zypper install -y curl
zypper install -y libopenssl-devel perl-FindBin-Real

# Install KDeltaChat dependencies
zypper install -y cmake gcc-c++
zypper install -y libqt5-qtbase-devel libQt5QuickControls2-devel libqt5-quickcontrols


Install system package for Kirigami, such as kirigami2-dev on Debian or Ubuntu, kirigami2 on Arch Linux or kirigami2-devel on OpenSUSE.


In kdeltachat directory, run:

cmake -B build .
cmake --build build


Run build/kdeltachat. Import existing account from backup or setup a new one.

#Using kdesrc-build

If your distribution does not package recent enough versions of the Kirigami framework, or you don't want to install libdeltachat system-wide, you can use kdesrc-build.

Install it with:

mkdir -p ~/kde/src
cd ~/kde/src
git clone https://invent.kde.org/sdk/kdesrc-build.git
cd kdesrc-build
./kdesrc-build kirigami


source ~/.config/kde-env-master.sh

in your shell to enter kdesrc-build environment.

To build libdeltachat with kdesrc-build, add module into ~/.kdesrc-buildrc as follows

module deltachat
   repository https://github.com/deltachat/deltachat-core-rust.git
end module

Then build libdeltachat with kdesrc-build deltachat.

Build Kirigami with kdesrc-build kirigami.

Then build kdeltachat as described above.


#Button icons are replaced with black rectangles

On Debian/Ubuntu, run apt purge libqt5quick5-gles. When apt offers to install libqt5quick5 as a replacement, agree.

Debian bugreport: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=976389

#Buttons have no icons

If you are not using KDE or another desktop environment with Qt 5 integration, you can install qt5ct, configure icon theme for Qt 5 there and set QT_QPA_PLATFORMTHEME=qt5ct or XDG_CURRENT_DESKTOP=qt5ct environment variable.

Setting XDG_CURRENT_DESKTOP=GNOME environment variable has also been reported to help in this case. This results in usage of Adwaita icon theme.
