Eclipse CDT: no rule to make target all

Question

My Eclipse CDT keeps complaining \"make: *** no rule to make target all\" when I am trying to compile the piece of code below:

#include 
us         


        

Answer 1

I got this same error after renaming and moving around source files. None of the proposed solutions worked for me and I tracked the error to be the meta-files under Debug directory not being updated. Deleting the entire Debug directory and re-build the project solved the problem for me.
