Building Cython-compiled python code with PyInstaller

Building a Cython-compiled Python code with PyInstaller involves a few steps to ensure that the Cython-compiled code is properly integrated into the final executable created by PyInstaller. Here's a general outline of the process:

  1. Write and Compile Cython Code: Write your Python code that includes Cython extensions. Save it with a .pyx extension. Use the cythonize command to compile the .pyx file into C code.

    cythonize -i your_module.pyx

  2. Create PyInstaller Spec File: Create a PyInstaller spec file that specifies the configuration for building your executable. You can generate a spec file using the pyinstaller command with the --name parameter and the --noconfirm flag:

    pyinstaller --name your_app_name --noconfirm your_script.py

  3. Modify the Spec File: Open the generated .spec file in a text editor and locate the EXE section. You'll need to add information about the compiled Cython module to the spec file. Add the following lines to the EXE section:

    a = Analysis(['your_script.py'],
             ...
             datas=[('your_cython_module.c', '.')],  # Add this line
             ...
             )

  4. Build the Executable: Build the executable using the modified spec file by running PyInstaller with the spec file as an argument:

    pyinstaller your_app_name.spec

    PyInstaller will then build the executable based on the spec file, which includes the Cython-compiled module.

  5. Test the Executable: After building the executable, test it to make sure that it functions as expected and that the Cython-compiled code is working properly.

Keep in mind that the specific steps and details might vary depending on your project's structure and requirements. It's also important to note that Cython-compiled code can introduce platform-specific considerations, so thorough testing on different platforms is recommended.

For more advanced scenarios or specific use cases, you might need to adjust the PyInstaller spec file further or use additional options.
