Adding more packages to a wstool generated workspace
I have made a source build of hydro using the instructions here (substituting hydro for groovy):
http://wiki.ros.org/groovy/Installation/Source
I followed REP 131 and only made a rosinstall including viz.
However, now I would like to add perception to the workspace. So I created a new rosinstall as such:
~/ros_catkin_ws$ rosinstall_generator perception --rosdistro hydro --deps --wet-only > hydro-perception-wet.rosinstall
~/ros_catkin_ws$ wstool init -j8 src hydro-perception-wet.rosinstall
But when I tried that I got the following error:
Error: There already is a workspace config file .rosinstall at "src". Use wstool install/modify.
I tried looking for documentation of wstool here:
But the documentation is sparse. When I type wstool help, I don't see either install or modify as options.
Is there a way to build upon a previous wstool-created workspace or do I need to make a ros_catkin_ws_2 or something like that?
Any help would be appreciated!
