Compilation error: pp_infer: Cannot locate rosdep definition for [pcl]

[franciscoascruz]

Hi!

I'm trying to use this package, but when I try to resolve the missing dependencies with rosdep using:

rosdep install -i --from-path src --rosdistro humble -y

I get the following error:

ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
pp_infer: Cannot locate rosdep definition for [pcl]

Does someone have a suggestion of what the problem could be?

I'm using:

• Ubuntu 22.04
• Ros Humble
• Cuda 12.0.1
• CudNN 8.8.0
• TensorRT 8.6.0.12
• and I have successfully installed TensorRT OSS

[UPDATE]

I edited the package.xml file and instead of using pcl I used pcl_ros which seems to work. However I still can't build the package successfully. Now I've got the following error. Any help, please?

Have you solved to build the package?

Can I know whether this package is compatible with ROS2 Humble on Ubuntu 22.04? If so, what is the TensorRT version that we have to install?
