I found that I can do the same with: set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -Wl,--no-export-dynamic")

Edited tutorial to reflect this.

2016-09-10 13:04:13 -0600 answered a question lookupTransform now not erroring as expected in tf python tutorial

Found it. In a previous step, we wrapped the lookupTransform call with

        except (tf.LookupException, tf.ConnectivityException, tf.ExtrapolationException):

Removing tf.ExtrapolationException for the list of handled exceptions allows the error to be reported.

Working through the Python version of the tf tutorial on page using Kinetic on Ubuntu 16.04.

For the first example on page: http://wiki.ros.org/tf/Tutorials/tf%2... an error is expected when asking for a lookupTransform with time set to rospy.Time.now().

The "chaser" turtle does not move, but no errors are reported. Can anyone else verify this? Perhaps the error is suppressed in newer versions of ROS?

Worked through the rest of the page and everything is working as expected.

Wasn't apparent to me at first. After the catkin_make you have to source the devel/setup.bash file again, even if you've done so before in that terminal.
