Reproduce this error by running:
==> cd /Users/alex/Code/ros/ros_catkin_ws/build_isolated/kdl_parser && /Users/alex/Code/ros/ros_catkin_ws/install_isolated/env.sh make -j4 -l4

Command failed, exiting.

What version of kdl_parser are you using, what version of boost, and what operating system are you using?

[wjwwood]

Looks like OS X.

[wjwwood]

Also, what is the version of orocos-kdl?

[spaghetti-]

@wjwwood sorry for the late reply, but I got it to compile by changing the link->second.children[] to link->second->children[] (everywhere needed).

afaik theres an open pull request that fixes these errors that we're supposed to pull in to fix it before building but I just did it manually.
Here: ros/robot_state_publisher#5

For the root of the issue see: orocos/orocos_kinematics_dynamics#4

[jacquelinekay]

The robot_state_publisher PR that you referenced in your last comment has been merged. Can I close this issue?

[jacquelinekay]

Closing this unless @spaghetti- or others report that this issue persists.
