PyOpenDDS

PyOpenDDS is a framework for using OpenDDS from Python. It has the goal of providing the standard full DDS API in OpenDDS in a Pythonic form.

This project is still a work in progress though. It currently only supports what is necessary for tests/basic_test and little else. See the GitHub issues for the current status of the limitations.

Requirements

• Tested on Linux, macOS, and Windows
• CPython >= 3.7
  • This uses the C API of CPython, so other Python implementations like PyPy are not offically supported.
  • If building Python from source, make sure to run the configure script with --enable-shared. PyOpenDDS doesn't currently support building with the statically-linkable Python library.
• OpenDDS >= 3.16
• CMake >= 3.12
• A compiler that supports C++14 or later.

Building PyOpenDDS and Running the Basic Test

Once $DDS_ROOT/setenv.sh has been sourced or the equivalent, run the commands below in this directory.

# Build and Install PyOpenDDS
pip install .

# Build Basic Test
cd tests/basic_test
mkdir build
cd build
cmake ..
make

# Build and Install Basic Test Python Type Support
itl2py -o basic_output basic_idl opendds_generated/basic.itl
# If using OpenDDS 3.19 or before, then just specify basic.itl
cd basic_output
pip install .

# Run Basic Test
cd ../..
bash run_test.sh
