Installing Kristall browser on Raspberry Pi 400
Kristall is a cute small browser supporting several protocols, including gemini, gopher and finger. This instruction works on recent versions of Raspberry Pi OS.
You can install it wherever you want, I chose to keep it in .local/share/.
Let's grab Kristall from GitHub and install missing QT5 and OpenSSL libraries.
It may take several minutes to finish.
git clone https://github.com/MasterQ32/kristall.git
sudo apt-get install qt5-default qtmultimedia5-dev libqt5svg5-dev libssl-dev
sudo make install
Now you can run Kristall.
