Hello, I recently compiled ROS Groovy from source on a fresh Ubuntu 12.04.1 install, using the instructions here: http://www.ros.org/wiki/groovy/Installation/Source I had to make the following changes to make it work, what is the right place to report this? I did what I described here: http://answers.ros.org/question/53401/error-when-compiling-pcl-for-ros-groovy-install-from-source-on-ubuntu-12041/ I installed a bunch of packages: sudo apt-get install libsdl-image1.2-dev libfltk1.3-dev automake libtool libprotobuf-dev libprotoc-dev libtar-dev libcegui-mk2-dev I symlink'd the .cmake files from ros_catkin_ws/install_isolated/share/rosbuild to ros_catkin_ws/install_isolated/share/ros/core/rosbuild/rostoolchain.cmake I removed common_rosdeps from a whole bunch of manifest.xml files Thanks, -- Sameer Parekh Falkor Systems, Inc.
