HUMBLE: Undefined symbol when launching bt_navigator about navigation2 HOT 5 CLOSED

Please review the package and try to find your error then :-) If this isn't an issue with Nav2 but rather your custom use of it, I can't provide much feedback or help beyond the fact that we have the nav2_bringup package & example for a reason 😄

from navigation2.

I tested the current humble binaries and don't have an issue - do you se this with ros2 launch nav2_bringup tb3_simulation_launch.py or only the TB3 launch files?

from navigation2.

Running ros2 launch nav2_bringup tb3_simulation_launch.py slam:=True it seems ok:

[component_container_isolated-5] [INFO] [1712736784.869636928] [lifecycle_manager_navigation]: Activating bt_navigator

Can send a goal to the robot and it goes by
The issue i reported earlier is also happening with my custom robot when trying to bringup nav2 with ros2 launch nav2_bringup navigation_launch.py use_sim_time:=True

Hi,
This problem occurs when nav2_bt_navigator node is run as a normal node and no issue when run as composable node.

In "tb3_simulation_launch.py" launch file, "use_composition" is set to True by default hence problem is not seen when "tb3_simulation_launch.py" is run with default configuration.

Use below command to see the issue with "tb3_simulation_launch.py".

ros2 launch nav2_bringup tb3_simulation_launch.py headless:=False use_composition:=False

Hope this will be fixed.

Using binaries

steve@reese:~$ apt info ros-humble-navigation2
Package: ros-humble-navigation2
Version: 1.1.14-1jammy.20240407.041637

I just tested your command and things work fine for me :-)

ros2 launch nav2_bringup tb3_simulation_launch.py headless:=False use_composition:=False

Its 1 version newer, but perhaps the issue is that you updated some dependencies below Nav2 but not Nav2 itself (like, BT.CPP) so that is causing the issue? That's a plausible explanation
