Hello, I am very new to ROS and have been stuck in this problem for a week. Currently trying to Install visp_ros but have not been able to in any way possible.

I am following specifically this tutorial http://docs.ros.org/en/noetic/api/visp_ros/html/tutorial-franka-coppeliasim.html I have tried to both build it from source and from using rosdep and both don't work.

Trying rosdep: Everytime I run:

rosdep install --from-paths src --ignore-src --rosdistro $ROS_DISTRO, 

I get the following message:

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

Have tried to find something online about how to install rosidl_default_generators but to no avail

So I tried following it building it from source. I have not been able to Build visp_ros package.

I have the vispros folder in my catkinws/src folder, and every time I run the

catkin_make --cmake-args -DCMAKE_BUILD_TYPE=Release -DVISP_DIR=~/software/visp/visp-build

I get the next error:

I have seen other solutions, one of them is to use catkin build instead of catkinmake, and, ignoring the fact that the previous steps tell me to use catkinmake, but I get a similar error:

And also using the catkinmakeisolated solution doesn't help

I tried installing it in a virtual machine with Ubuntu 20.04 and another one with Ubuntu 18.04 machine. Both are using ROS 1, and this errors are from the 18.04 with the next specifications, these are all run on virtual machine: Distributor ID: Ubuntu Description: Ubuntu 18.04.6 LTS Release: 18.04 Codename: bionic

Would appreciate it a lot if someone could give me some feedback on a possible solution. Literally created a new, fresh machine and just did the tutorial to see if something was wrong or had conflict with the previous one I had but the problem persists and I cannot use VISP.
