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

"all" is a default setting, even though Behaviour->Build (Incremental build) tab has no variable. I solved as

1. Go to Project Properties > C/C++ Build > Behaviour Tab.
2. Leave Build (Incremental Build) Checked.
3. Enter "test" in the text box next to Build (Incremental Build).
4. Build Project. You will see error message.
5. Go back to Build (Incremental Build) and delete "test".
6. Build Project.
