Building Python auxiliary libraries

eProsima Fast DDS-Gen can generate the required source files and CMake project to build the Python modules that allow the use of the IDL defined data types within a Fast DDS Python-based application. Each IDL file will result in a new Python module that will contain all the data types defined in the file. The Python binding is generated building the provided solution using SWIG.

Calling eProsima Fast DDS-Gen with the option -python will generate these files. eProsima Fast DDS-Gen will generate a .i file which will be processed by SWIG and a CMake project to call SWIG first generating C++ files (for connecting C++ and Python) and Python files (Python module for your type) and then compiling the C++ sources.

Before calling CMake, the :ref:`fastddsgen_python_build` process needs several :ref:`fastddsgen_python_deps` to be met.

Dependencies

Building

Call CMake:

mkdir build
cd build
cmake ..
cmake --build .

This will create the Python files (.py) with the modules (one per each IDL file) that have to be imported within the Python script.
