I have added
export ROS_PACKAGE_PATH="/home/kathir/ORB_SLAM":${ROS_PACKAGE_PATH}
in .bashrc and I am getting this error during cmake of ORB_SLAM.
ORB_SLAM cloned path : "/home/kathir/ORB_SLAM"
I have another workspace in "/home/kathir/catkin_ws/devel/setup.bash" in the .bashrc since I was using ROS for ARDRONE.
CMake Error at /opt/ros/indigo/share/ros/core/rosbuild/private.cmake:102 (message):
[rosbuild] rospack found package "ORB_SLAM" at "", but the current
directory is "/home/kathir/ORB_SLAM". You should double-check your
ROS_PACKAGE_PATH to ensure that packages are found in the correct
precedence order.
check below for further info
kathir@kathir-VirtualBox:~/ORB_SLAM/build$ source .bashrc
bash: .bashrc: No such file or directory
kathir@kathir-VirtualBox:~/ORB_SLAM/build$ $ROS_PACKAGE_PATH
bash: /opt/ros/indigo/share:/opt/ros/indigo/stacks:M$:: No such file or directory
The error you are likely seeing is because of your exported variables not taking effect in your current shell. You need it to source it in the current shell for it to take effect,
source ~/.bashrc
or more simply just
. ~/.bashrc
which imports all the new environment variables to the existing session. You don't have do this for subsequent sessions, as this will be sourced for every new session opened upon startup.
