Since console_bridge is ROS-independent should it go in a ROS workspace or simply in with the debian/Ubuntu somewhere (like with bootstrap dependencies)?

As it is not a catkin package it cannot go in a catkin workspace.

I'm installing on a BeagleBone so Groovy must be installed from source (if this makes any difference in the answer).

The easiest way to use console_bridge is to install it from binary packages (sudo apt-get install ros-groovy-console-bridge).

If you want to build it from source, note that console_bridge is NOT a catkin project, but rather a pure CMake project. You should keep it separate from a catkin workspace, build it with CMake, "make install" it somewhere, and then make sure that when you build code against it, that it can be find_packaged() by CMake (i.e. console_bridge and it's .cmake file need to be findable through CMAKE_PREFIX_PATH environment variable).

Hope that helps, let me know if you need clarification.

Edit: mkdir cb_ws
cd cb_ws
git clone https://github.com/ros/console_bridge
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=../install ../console_bridge
make install

This will create a folder called install within the folder cb_ws.

Inside the install folder you'll see: include/ lib/ share/

Within "share" you'll see the generated file console_bridge.cmake. This is what cmake uses to figure out where console_bridge is installed (which is cb_ws/install). Your CMAKE_PREFIX_PATH variable needs to point to the folder that contains this file so taht CMake can find it and determine -I flags (in this case cb_ws/install/include), -L flags (in this case cb_ws/install/lib) and -l flags (in this case libconsole_bridge.so which to the compiler will be "-lconsole_bridge").

I edited the comment above with more clarification, let me know if it still doesn't make sense...I know this stuff can be confusing. Also again, it is way easier to use the binary .deb packages. Unless you have a good reason to build it from source, it's just making life harder for yourself.

I'm okay building from the binary.deb packages, I'm just not sure where to put it. My catkin_ws has packages that have console_bridge as a dependency so I want to make sure to install it where they can find it.

Ah I understand now, this is easier than you think :) If you install from debian packages then it's all already taken care of for you. As long as you source your ros environment (e.g. source /opt/ros/groovy/setup.bash), the CMAKE_PREFIX_PATH will automatically be set..

This still presents a question as with the groovy install from source instructions nothing goes into /opt. The install path is home/ubuntu/ros_catkin_ws. I've tried to instal in the ros_catkin_ws but as you mentioned, this won't work. I tried in home/ubuntu but got "unable to locate package..."

You don't use the source install instructions -- forget the source code! Just do: 1) sudo apt-get install ros-groovy-console-bridge 2) source /opt/ros/groovy/setup.bash

Done! Anywhere find_package(console_bridge) is used in any CMakeLists.txt file, it will be resolved

Okay... maybe a miscommunication. I'm installing on a BeagleBone so I must install Groovy from source (http://www.ros.org/wiki/groovy/Installation/Source). At my root I'm at ubuntu@arm:$. An 'ls' command gives me my only directory (ros_catkin_ws).

There were two cd cb_ws and the CMAKE_ISNTALL_PREFIX was missing D at the front. I fixed them in the answer.

Hey sorry I had mistyped those instructions, @tfoote has corrected them. I can't remember off the top of my head what the CMAKE_INSTALL_PREFIX has to be. I'm a bit busy at the moment, please check out the CMake documentation. If you can't still solve it, I can take a look at it in a few hours when I
