I am trying to compile an example code in cooja simulator on contiki-2.7 Operating System. Contiki is an OS for IoT applications. It is built based on the Linux kernel and on C programming language.
Before implementing in hardware the code is tested in cooja simulator. For a research purpose I installed contiki-2.7 in VirtualBox, and I'm trying to execute some codes in cooja simulator, but I can't compile any of the example codes for this simulation.
For compilation of any code the simulator shows me the error:
make*** No rule to make target 'obj_sky/neighbour-attr.o' needed bt 'contiki-sky.a' Stop. Process returned error code 2
How can I fix this error? It is very important to me. I am not getting enough resources from Google.
