Hello everyone,
I’m trying to implement the ROS2 bridge with RTMAPS, and facing dependency issues:
OS: Ubuntu 22.04
ROS2: Humble
RTMaps : v4.12.0
I installed the ros2 humble and ros2 bridge rtmaps packages:
ros2_humble from Link
ros2 bridge from Bridge Link
i’ve installed everything as needed and can see the files under /opt/rtmaps/packages, but when i try to load the package i get the following error:
Error: Unable to load package /opt/rtmaps/packages/rtmaps_ros2_bridge_core_function.pck: third party dependencies may be missing (.dll/.so/.dylib files). liblibstatistics_collector.so: cannot open shared object file: No such file or directory
register <</opt/rtmaps/packages/rtmaps_ros2_bridge_core_function.pck>>
i check the existence of the said liblibstatistics_collector.so file, and this is the output
regastation@regastation-System-Product-Name:~$ find /opt/ros/humble -name liblibstatistics_collector.so
/opt/ros/humble/lib/liblibstatistics_collector.so

according to the ros bridge trouble-shooting page -
I tried both option 1 & 2, but i still get the error
Please help sort this out.
