Running DeltaTouch on Arch Linux

1

DeltaTouch can be run natively on Arch Linux. Here are some notes on how to build and run it without proper packaging.

DeltaTouch depends on lomiri-ui-toolkit, which needs to be installed from AUR first: AUR (en) - lomiri-ui-toolkit
This in turn depends on another dependency not officially packaged, qt5-pim, which can be installed from AUR (en) - qt5-pim-git

Building DeltaTouch also requires installing AUR (en) - quirc

You also need to build libdeltachat.so, I assume it is available at /path/to/libdeltachat.so.

After installing the dependencies, I checked out the commit Making sure you're not a bot!

#!/bin/sh
set -eu

sed -i 's/VERSION 3.0.0/VERSION 4.0.0/' CMakeLists.txt

cmake -B build

mkdir -p build/plugins/DeltaHandler/
mkdir -p build/plugins/XdcPickerEngineProfile/

cp /usr/lib/libquirc.so build/plugins/DeltaHandler/libquirc.so.1.2

for plugin in DeltaHandler XdcPickerEngineProfile HtmlMsgEngineProfile WebxdcEngineProfile; do
        cp /path/to/libdeltachat.so "build/plugins/$plugin/"
        cp plugins/$plugin/qmldir build/plugins/$plugin/$plugin/
done

# Build
cmake --build build

Then run it with this script in the source dir:

#!/bin/sh
export QML2_IMPORT_PATH="$PWD/build/plugins/DeltaHandler/:$PWD/build/plugins/XdcPickerEngineProfile/"
build/deltatouch

Now when checking out commit 73f0e72d763de4af2d8f0f91ff86d3ce39dfe6b3 with PR #34 - Import libdeltachat and libquirc without copying them into the bulid tree - lk108/deltatouch - Codeberg.org merged it is enough to run this:

cmake -B build -D CMAKE_INSTALL_PREFIX=/usr
cmake --build build
DESTDIR="$PWD/pkg" cmake --install build/

export QML2_IMPORT_PATH="$PWD/pkg/lib/"
pkg/usr/deltatouch

DeltaTouch is available in AUR now:
