## 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:
|
|
```bash
|
|
pip install -r requirements.txt
|
|
```
|
|
|
|
### Build Steps
|
|
|
|
1. Open a terminal in the project's root directory.
|
|
2. Run the build script:
|
|
```bash
|
|
python build_app.py
|
|
```
|
|
3. The build script will clean previous builds, detect your OS, and run PyInstaller with the correct configuration.
|
|
4. Once complete, the standalone executable will be available in the `dist/` folder:
|
|
- **Linux:** `dist/TeletextEditor_Linux`
|
|
- **Windows:** `dist/TeletextEditor_Windows.exe`
|
|
|
|
> **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.
