# KDeltaChat
KDeltaChat is a [Delta Chat](https://delta.chat/) client using [Kirigami](https://develop.kde.org/frameworks/kirigami/) framework.
# Dependencies
KDeltaChat build depends on
[libdeltachat](https://github.com/deltachat/deltachat-core-rust/),
Kirigami framework and several QML modules.
## libdeltachat
`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
```
## Qt
Install QtQuick and required QML modules using your system package manager.
### Debian
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
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
```
## Kirigami
Install system package for Kirigami, such as `kirigami2-dev` on Debian
or Ubuntu, `kirigami2` on Arch Linux or `kirigami2-devel` on OpenSUSE.
# Building
In `kdeltachat` directory, run:
```
cmake -B build .
cmake --build build
```
# Running
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](https://kdesrc-build.kde.org/).
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-setup
./kdesrc-build kirigami
```
Run
```
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.
# Troubleshooting
## 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](https://sourceforge.net/projects/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.
