undefined symbol: rmw_time_equal

[kpwelsh]

Hi,

I am trying to run this project with ROS2-Humble on Ubuntu-22.04 with UE5.1. Everything is a fresh install.

It seems that I have almost gotten it to run, but when I try to launch this project, I receive the following error:

symbol lookup error: /opt/ros/humble/lib/librmw_fastrtps_shared_cpp.so: undefined symbol: rmw_time_equal

Perhaps unrelated, but also whenever I make the editor I can no longer run "fastdds discovery -i 0" until I restart. That yields:

024-01-31 17:00:43.854 [RTPS_PARTICIPANT Error] Discovery Server wasn't able to allocate the specified listening port. -> Function createParticipant
Server creation failed with the given settings. Please review locators setup.
2024-01-31 17:00:43.856 [DOMAIN_PARTICIPANT Error] Problem creating RTPSParticipant -> Function enable
fastdds discovery <discovery-args>

 fast-discovery-server tool not found!

Any tips would be appreciated :).

Nevermind.

I had a mismatch of branches checked out. Getting messages now.
