Revision history [back]

I kept hammering away at this and found the solution (at least it got past that part). Apparently, ROS is moving away from boost::shared_ptr and moving toward using the std::shared_ptr available in c++11 and higher. Because the instructions at http://wiki.ros.org/ROSberryPi/Installing%20ROS%20Indigo%20on%20Raspberry%20Pi are a mix of installing packages and installing from source, this caused a discrepency where urdfdom_headers was a newer version that had the conversion from boost::shared_ptr to std::shared_ptr completed, but the rest of ROS Indigo is still expecting boost::shared_ptr.

So, the solution was to go back and find the last commit at https://github.com/ros/urdfdom_headers/commits/master that still had the boost::shared_ptr in the types.h file. Interestingly enough, you and I both originally thought that we needed to add c++11 support because types.h was using std::shared_ptr. This solved the problems of the std::shared_ptr support, but introduced new ones where it was trying to assign an std::shared_ptr to a boost::shared_ptr and vice versa.

The section should become

liburdfdom-headers-dev:

cd ~/ros_catkin_ws/external_src
$ git clone https://github.com/ros/urdfdom_headers.git
$ cd urdfdom_headers
$ git reset --hard 9aed725
$ cmake .
$ sudo checkinstall make install

Here the 'git reset --hard 9aed725' moved the revision back to the point where boost::shared_ptr is still in there.
