Unable to build ORB_SLAM3 with ROS using ./build_ros.sh on ubuntu 20.04 with ros-noetic-desktop-full

[rioter1]

I have installed ros-noetic-desktop-full Paths for ros_root and ros_package are echo $ROS_ROOT /opt/ros/noetic/share/ros echo $ROS_PACKAGE_PATH /opt/ros/noetic/share:~/ORB_SLAM3/Examples_old/ROS/ORB_SLAM3

after running ./build_ros.sh, I get

[rosbuild] Building package ORB_SLAM3 Failed to invoke /opt/ros/noetic/bin/rospack deps-manifests ORB_SLAM3 ModuleNotFoundError: No module named 'rosdep2' [rospack] Error: could not find python module 'rosdep2.rospack'. is rosdep up-to-date (at least 0.10.4)?

CMake Error at /opt/ros/noetic/share/ros/core/rosbuild/public.cmake:129 (message):

Failed to invoke rospack to get compile flags for package 'ORB_SLAM3'. Look above for errors from rospack itself. Aborting. Please fix the broken dependency!

I can solve the rosdep error by doing source /opt/ros/noetic/setup.bash but this changes my ROS_PACKAGE_PATH to echo $ROS_PACKAGE_PATH /opt/ros/noetic/share and gives new error [rosbuild] Error from directory check: /opt/ros/noetic/share/ros/core/rosbuild/bin/check_same_directories.py /home/antpc/orbslam/ORB_SLAM3/Examples_old/ROS/ORB_SLAM3 1 Traceback (most recent call last): File "/opt/ros/noetic/share/ros/core/rosbuild/bin/check_same_directories.py", line 46, in raise Exception Exception CMake Error at /opt/ros/noetic/share/ros/core/rosbuild/private.cmake:99 (message): [rosbuild] rospack found package "ORB_SLAM3" at "", but the current directory is "~/orbslam/ORB_SLAM3/Examples_old/ROS/ORB_SLAM3". You should double-check your ROS_PACKAGE_PATH to ensure that packages are found in the correct precedence order.

If I do export ROS_PACKAGE_PATH=${ROS_PACKAGE_PATH}:~/orbslam/ORB_SLAM3/Examples_old/ROS/ORB_SLAM3 as is the error above, I again get the rosdep2 error Error: could not find python module 'rosdep2.rospack'

Its like I am going in circles.

Try to make the path to ~/ORB_SLAM3/Examples_old/ros instead of ~/ORB_SLAM3/Examples_old/ros/ORB_SLAM3 and maybe avoid using tilda in the path

Did you run "rosdep update" after finishing the ros installation

I am sorry but just to make sure, you ran "rosdep update" after "sudo rosdep init" after installation.

yes I ran rosdep update after I ran sudo rosdep init after installation

I recommend that you clone any cpp ros package and try to build it in a catkin workspace to ensure that you have a clean ros installation.

will give that a shot. Thanks for your responses Khaled!

I resolved the errors by purging ros-noetic from my system and reinstalling it. didn't require catkin_make just used the standard ros install as per http://wiki.ros.org/noetic/Installation/Ubuntu. Thanks Khaled!
