I have encounterd rthe above error and tried to solve it with similar errors others have faced. but till now no clue how to solve this error. anyone knows? `sudo ./build_ros.sh [sudo] password for orbslam: Building ROS nodes mkdir: cannot create directory ‘build’: File exists CMake Error at CMakeLists.txt:2 (include): include could not find load file:

Got the same problem, the think is that if you use sudo you lose your defined vars. So change the perms to the root directory recursively so you wont get the perms errors when you build it without sudo.

I have done the following

sudo chown -R myusername:root ORB_SLAM2

then I go in ORB directory and run

./build_ros.sh

I was encountering the same error. Reinstalling the full desktop version of ROS (Hydro or newer, I installed kinetic with $ sudo apt-get install ros-kinetic-desktop-full). Then followed the configuration options on ROS's website. So, try uninstalling ros, and reinstalling the ros-#distro#-desktop-full following the exact options for your ros distrobution (http://wiki.ros.org/Distributions)

Hi. Same error i faced Ubuntu 16 Ros Kinetic

But it got resolved by below

Add the path including Examples/ROS/ORB_SLAM2 to the ROS_PACKAGE_PATH environment variable. Open .bashrc file and add at the end the following line. Replace PATH by the folder where you cloned ORB_SLAM2:

[kunnalparihar]

I faced the same error in Kinetic It is working now by adding the following line in ~/.bashrc file. Replace PATH by the folder where you cloned ORB_SLAM2. export ROS_PACKAGE_PATH=${ROS_PACKAGE_PATH}:PATH/ORB_SLAM2/Examples/ROS

then run $ source ~/.bashrc

check that $ echo $ROS_PACKAGE_PATH should give /opt/ros/kinetic/share:PATH/ORB_SLAM2/Examples/ROS

$echo $ROS_ROOT should give /opt/ros/kinetic/share/ros

$echo $ROS_ROOT should give /opt/ros/kinetic/share/ros

i have tried this method, but it still not worked and gave following errors: Building ROS nodes mkdir: cannot create directory ‘build’: File exists [rosbuild] Building package ORB_SLAM2 [rosbuild] Error from directory check: /opt/ros/kinetic/share/ros/core/rosbuild/bin/check_same_directories.py /home/daiwj5/catkin_ws/src/ORB_SLAM2/Examples/ROS/ORB_SLAM2 1 Traceback (most recent call last): File "/opt/ros/kinetic/share/ros/core/rosbuild/bin/check_same_directories.py", line 46, in raise Exception Exception CMake Error at /opt/ros/kinetic/share/ros/core/rosbuild/private.cmake:102 (message): [rosbuild] rospack found package "ORB_SLAM2" at "", but the current directory is "/home/daiwj5/catkin_ws/src/ORB_SLAM2/Examples/ROS/ORB_SLAM2".

Hello All,

I am also getting the following error when I tried to build ORB_SLAM2 in ros. The error message is as follows.

//FOLLOWED step

sudo gedit \.bashrc

export `ROS_PACKAGE_PATH=${ROS_PACKAGE_PATH}:/home/ajay/orb_slam_ws/src/ORB_SLAM2/Examples/ROS/ORB_SLAM2`

source ~/.bashrc

But still, I am unable to figure out the root of the issue. Could anyone please give me some suggestions. Your help much appreciated

Thanks. AJay

[Keerthan020]

I had the same issue, it was solved when you add the line export ROS_PACKAGE_PATH=${ROS_PACKAGE_PATH}:PATH/ORB_SLAM2/Examples/ROS at the end of ~/.bashrc and not in between, hope this helped. :)

[ajay1606]

@Keerthan020 Thank you so much for your kind response. Yes, it is working now.

[IMHinnG]

It must be enter root the user to modify ,otherwise it is invalid !!!!!!!!!! ,my system is Ubuntu 16.04.1

[tungtungyan]

My result is this. echo $ROS_PACKAGE_PATH /opt/ros/melodic/share:/media/ytl/2TB/catkin_orb/src/ORB_SLAM3/Examples/ROS:PATH/ORB_SLAM2_modified/Examples/ROS How can I remove the medium part ? (/media/ytl/2TB/catkin_orb/src/ORB_SLAM3/Examples/ROS)

./build_ros.sh Building ROS nodes mkdir: cannot create directory ‘build’: File exists CMake Warning (dev) in CMakeLists.txt: No project() command is present. The top-level CMakeLists.txt file must contain a literal, direct call to the project() command. Add a line of code such as

near the top of the file, but after cmake_minimum_required().

CMake is pretending there is a "project(Project)" command on the first line. This warning is for project developers. Use -Wno-dev to suppress it.
