Move group diying

[t-glez]

Description

I am using ROS2 to control a UR5e with the UR_ROS2_Drivers. It works when using the binary release. When using the source built version move group dies.

ROS Distro

Humble

OS and version

Ubuntu 22.04

Source or binary build?

Source

If binary, which release version?

No response

If source, which branch?

Main

Which RMW are you using?

CycloneDDS

Steps to Reproduce

Code for calling the move_group node

Move group should upload the libraries and publish the planning scene

Backtrace or Console output

Could you share your full console log? Usually there are other errors above the part you shared that indicate the actual problem.

launch.log

[mikeferguson]

I would suggest uninstalling the moveit debians, and rebuilding your workspace. There are some ABI incompatibilities between what is in debs and what is in source and that definitely leads to some of these stranger crashes
