Qrca

Qrca is a simple application for Plasma Desktop and Plasma Mobile that lets you scan many barcode formats and create your own QR code images.

Get it

Qrca is currently available on Linux as a nightly Flatpak:

flatpak install --user https://cdn.kde.org/flatpak/qrca-nightly/org.kde.qrca.flatpakref

Qrca is also available as a nightly for Android on F-Droid with the KDE F-Droid Nightly Build Repository.

The most well supported way to build Qrca is with kde-builder.

Follow the tutorial to get started with kde-builder, then run:

# To build
kde-builder qrca
# To run
kde-builder --run qrca

To build the project manually and install it locally, run:

# To build
cmake -B build/
cmake --build build/ --parallel
cmake --install build/ --prefix ~/.local
# To run
