Copied Workspace, now Problem with rosdep

edit

Hi guys,

I accidentally deleted my plattform but could save my workspace somehow. Now i set up a new Ros Indigo with Ubuntu 14.04 same stuff as before. I copied my data in my new workspace and sourced the setup.bash.

Now I am trying to "make" again the nodes to be usable on the new system but when I am doing make it says:

moviplc@moviplc:~$ source ~/indigo_ws/setup.bash 
moviplc@moviplc:~$ roscd twist_to_odom/


moviplc@moviplc:~/indigo_ws/sandbox/roche_control/twist_to_odom$ make
mkdir -p bin
cd build && cmake -Wdev -DCMAKE_TOOLCHAIN_FILE=/opt/ros/indigo/share/ros/core/rosbuild/rostoolchain.cmake  ..
