tf package missing from ROS build.

[WillieMaddox]

When I run ./build_ros.sh from the root of the project I fail for missing package dependencies.

maddoxw@wmdevbox:~/git/ORB_SLAM2$ ./build_ros.sh

[rosbuild] Building package ORB_SLAM2
Failed to invoke /usr/bin/rospack deps-manifests ORB_SLAM2
[rospack] Error: package 'ORB_SLAM2' depends on non-existent package 'tf' and rosdep claims that it is not a system dependency. Check the ROS_PACKAGE_PATH or try calling 'rosdep update'

My ROS paths are as follows:

maddoxw@wmdevbox:~/git/ORB_SLAM2$ printenv | grep ROS
ROS_ROOT=/usr/share/ros
ROS_PACKAGE_PATH=:/usr/lib/x86_64-linux-gnu:/home/maddoxw/git/ORB_SLAM2/Examples/ROS

And when I try to install the missing dep, I get errors.

maddoxw@wmdevbox:~/git/ORB_SLAM2$ rosdep install tf

ERROR: Rosdep cannot find all required resources to answer your query
Missing resource tf
ROS path [0]=/usr/share/ros
ROS path [1]=/usr/lib/x86_64-linux-gnu
ROS path [2]=/home/maddoxw/git/ORB_SLAM2/Examples/ROS
ROS path [3]=/usr/share

I probably have my paths messed up, but It's not obvious to me how? I'm on Ubuntu 16.04.

Suggestions?

Thanks.

rosdep doesn't install tf itself, but only its system dependencies. Install tf first
