Maybe figuring out the reason why the `talker` fails helps in determining the cause for the `talker__rmw_connext_cpp`. I assume you have sourced the `local_setup.bash` file before trying to run any of the binaries? Can you test which library poco is failing to load. E.g. run the `talker` within `gdb` and print the `library_path`. --- [Visit Topic](https://discourse.ros.org/t/talker-example-issue-with-beta-1/992/8) or reply to this email to respond.
