Can you give some information on what steps you followed to install Humble?

deepak-anzo commented 7 months ago

Thank you for your reply. I followed the the official documentation https://docs.ros.org/en/humble/Installation/Ubuntu-Install-Debians.html

clalancette commented 7 months ago

So it kind of looks like the installation isn't correct, for some reason. Can you tell us:

1) What commands you were running at the time 2) What ls /opt/ros/humble/lib/x86_64-linux-gnu/libddsc* shows?

I have the same situation, you can try sudo apt-get install -y ros-humble-rmw-cyclonedds-cpp

@deepak-anzo can you go through https://docs.ros.org/en/humble/Installation/DDS-Implementations/Working-with-Eclipse-CycloneDDS.html? i think you are just missing the cyclone dds package.

deepak-anzo commented 4 months ago

I found the solution for this. Just put /opt/ros/humble/lib/x86_64-linux-gnu in your ld config file.
