Can you please post the content of one of these files (e.g. `share/ament_index_cpp/environment/library_path.sh`). Just to make sure it extends the environment variable as it is supposed to. In the list of sourced files is there an entry for RTIs Connext? Maybe that one overwrites the environment variable? The failing test in `osrf_pycommon` happens the same for me. Don't worry about that one. Happy New Year for you too! --- [Visit Topic](https://discourse.ros.org/t/talker-example-issue-with-beta-1/992/23) or reply to this email to respond.
