wxPython is required. In Windows, Microsoft Visual C++ redistributable is required. I find that everything works with Python 3.7.3 in Debian and Python 3.8.6 in Windows 10, but Python 3.9.0 does not appear to work on Windows 10.
Debian requires python3-wxgtk to be installed via your package manager. For example, on a Raspberry Pi 4 as of this writing, the version is python3-wxgtk4.0-4.0.4+dfsg-2.
This python script can be run using "python3 -m mechcalc" on the command line or by creating a shortcut.
In Debian, a desktop shortcut can be created by creating a file with a .desktop extension (e.g., "MechCalc.desktop"). Make the contents this:
Exec=python3 -m mechcalc
In Windows, right-click on the desktop or in file explorer and create a shortcut. Right click again and select Properties. Enter "<your python install directory>\pythonw.exe -m mechcalc" in the "Target:" field, and <your python install directory> in the "Start in:" field. ("pythonw.exe" starts the script without a command line console.)
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
