Eror in ros basics

i keep getting that error

Invoking “cmake” failed

i tried to delete devel and build and use catkin_make but no change
it says that it cannot find “iri_warm_reproduce_trajectory” package also but i am sure i did every thing write.

the full messag is

I suppose you are doing exercise 5, and running your code in the unit 6 - Understanding ROS Services - Clients.

Before running catkin_make, try:

source /home/simulations/public_sim_ws/devel/setup.bash
