4. 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 proper Python binding is generated building the provided solution using SWIG.
After generating the files using eProsima Fast DDS-Gen with the -python option your workspace will include the SWIG interface files (.i) required to build the data type’s Python modules; use the generated CMakeFile to build the data types and create the Python bindings:
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.
