Undefined Symbol when compiling in different workspace [closed]

edit

System details:

ROS Noetic, Ubuntu 20.04

Mambaforge environment with Robostack installed, for one robostack_catkin_ws

System ROS-noetic installed for another catkin_ws

I have a package that is an octomap_server overlay, and it compiles and runs fine within the system ROS catkin_ws. The package compiles but does not run in the robostack_catkin_ws, in the mambaforge environment. The error is as follows:

``` catkin_ws/devel/lib/octomap_server/octomap_server_node: symbol lookup error: /home/joe/mambaforge/envs/change_env/lib/liboctomap_server.so: undefined symbol: _ZN3pcl13FilterIndicesINS_8PointXYZEE11applyFilterERNS_10PointCloudIS1_EE [octomap_server-1] process has died [pid 3155514, exit code 127, cmd /home/joe/softgroup_catkin_ws/devel/lib/octomap_server/octomap_server_node cloud_in:=/vilens/point_cloud_transformed_processed __name:=octomap_server __log:=/home/joe/.ros/log/5a0ad4da-35d0-11ee-b198-43fb6e5adf08/octomap_server-1.log]. log file: /home/joe/.ros/log/5a0ad4da-35d0-11ee-b198-43fb6e5adf08/octomap_server-1*.log

``` I assumed this was a mismatch in the pcl versions that the octomap_server package was compiled with, so i checked pcl verison in both environments.

mamba list | grep pcl-ros $ ros-noetic-pcl-ros 1.7.4 py39h7e6a3dc_15 robostack-staging

mamba list | grep pcl-conv ros-noetic-pcl-conversions 1.7.4 py39h7e6a3dc_15 robostack-staging

and in the system environment:

```apt-cache policy ros-noetic-pcl-conversions $ ros-noetic-pcl-conversions:

```

```

apt-cache policy ros-noetic-pcl-ros$ ros-noetic-pcl-ros: Installed: 1.7.4-1focal.20230216.013505 Candidate: 1.7.4-1focal.20230620.195801 Version table: 1.7.4-1focal.20230620.195801 500 500 http://packages.ros.org/ros/ubuntu focal/main amd64 Packages *1.7.4-1focal.20230216.013505 100 100 /var/lib/dpkg/status 1.7.4-1focal.20220221.102136 500 500 https://packages-ros.anybotics.com/ro... focal/main amd64 Packages 1.7.1-2focal 500 500 https://packages.anybotics.com/anymal... focal/main amd64 Packages ```

So, the versions are all 1.7.4, and I am stumped as to why I am getting the undefined symbol error.
