How to Build Manually
The application is built using Python and PyQt6, and packaged into a standalone executable using PyInstaller. A helper script build_app.py is provided to streamline the process.
Prerequisites
- Python 3.10 or higher
- Install dependencies:
pip install -r requirements.txt
Build Steps
- Open a terminal in the project's root directory.
- Run the build script:
python build_app.py - The build script will clean previous builds, detect your OS, and run PyInstaller with the correct configuration.
- Once complete, the standalone executable will be available in the
dist/folder:- Linux:
dist/TeletextEditor_Linux - Windows:
dist/TeletextEditor_Windows.exe
- Linux:
Note for Cross-Compilation: The build script produces an executable for the current OS running the script. To build the Windows executable on Linux, you can use Wine (as configured in the Gitea workflow) or run the script natively on a Windows machine.
