OctoMap installation

edit

Uhm, I see. So I should copy it in the workspace/src and then install it manually, and then catkin_make at the root of the workspace? Sorry but I am not sure about all these processes, they are new to me.

The point is that I already have some OctoMap packages under opt/ros/indigo/share (that I installed along with other things I previously installed, the robot and MoveIt!, I guess), so I don't want to overwrite them. That's why I want to do this in a separate workspace, for experimenting with it.

Don't put it in your workspace at all (the octomap-lib, because it is not a catkin package). Only catkin-packages should go into your workspace. It will then be installed to /usr/local. However catkin package will likely use your octomap from the ros-binaries, so you might have to unistall these.

Btw. I agree with mig's comment, why don't you use the deb-installed octomap that comes with ros (and is already installed on your system?)

Ok, I finally installed it from debs (sudo apt-get install ros-indigo-octomap ros-indigo-octovis). Thank you. But there is nothing that is contained here ( https://github.com/OctoMap/octomap ), no .cpp, no files, no nothing. Just an empty shell. How do I use it now? For opening octovis, for example.

I asked a different question for being more specific on my problem: http://answers.ros.org/question/25606... If you know the answer, please answer there. It would be extremely helpful.
