undefined reference to `YAML::detail::node_data::push_back(YAML::detail::node&, boost::shared_ptr<YAML::detail::memory_holder>)' #115

I got this error while running catkin build:

Errors     << mav_trajectory_generation:make /home/kadhir/catkin_ws/logs/mav_trajectory_generation/build.make.003.log

When following the installation instructions, I first ran into Could not find a package configuration file provided by "yaml_cpp_catkin". To solve that, I ran git clone https://github.com/ethz-asl/yaml_cpp_catkin.git inside ~/catkin_ws/src, and then reran catkin build, which is when I got this error. What steps do I take to fix it? Any help would be greatly appreciated!

Fixed the error by reverting to a previous copy of catkin_ws that I had made, and following the instructions in #106
