The GUI requires a python installation with tkinter

git clone https://github.com/CSCfi/crypt4gh-gui
pip install -r requirements.txt

python crypt4gh_gui.py

Standalone executable build requires:

• pyinstaller

The GUI can be built into a standalone executable and distributed to machines that don't have python installed. After running the pyinstaller command, the standalone executable file can be found in the dist/ directory.

pip install pyinstaller

pyinstaller --onefile crypt4gh_gui.py

This has been tested on Linux and Windows.

To run the executable on Linux:

./crypt4gh_gui

To run the executable on Windows:

• Double click on crypt4gh_gui.exe or run the following in cmd:

crypt4gh_gui.exe

You can download a pre-built executable from the releases page.

1. Download a zip archive for your current operating system
2. Extract the archive to get the executable

Note that the Linux and Windows builds are created with amd64 architecture, and the MacOS build is created with arm64 architecture. For other architectures you must build the executable yourself with the instructions above.
