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  ..

Seems your current user doesn't have access to ~/.ros/rosdep/sources.cache/index. Did you copy your entire home dir to your new system? If so, it could be that the rosdep cache is owned by your old user (the username may be the same, but the uid most likely isn't).

Can you check what the output is of ls -al ~/.ros/rosdep/sources.cache/index?

A quick fix would be to remove the entire ~/.ros/rosdep dir, then do a rosdep update. If the permissions of ~/.ros are ok, that should get rosdep to recreate its cache - with the proper permissions.
