Linker errors while compiling with Open3D

[rawnam]

Hi
I am getting linker errors with Open3D. I tried adding rclcpp in cmakelists but it doesn't help
Following is my build environment:

• Ubuntu 22.04
• Ros Humble
• Opencv 4.6.0
  err.txt

Please help

Thanks that works. Would the open3d functionality be available later?

You need to compile Open3D from src rather than install it from pip3. I didn't install Open3D in the latest test so the function is not available now.

I will find some time to resolve the open3d compiling issue.
