Hi @282902479,

Fast DDS Python bindings require SWIG version 4.0 in order to build. I have checked the documentation and it is true that this dependency requirement is not clearly stated. Sorry for the inconvenient! Please, upgrade your SWIG version and try again, and let me know if you have any other issue. I will leave this ticket open until a PR is merged stating the minimum required SWIG version to build the Python bindings.

Thanks for your contribution!
