Nothing to be done for first

[Salazaar]

Hi. I have a problem. You already know my project files, maker.h, maker.cpp, ui_maker.h and main.cpp. If I try to compile the project, there appear:
[1]make - Nothing to be done for 'first'
I don't know what's wrong. I didn't change the code, so the could not appear new error!

It just says it can't compile the project because it's already compiled. Try calling make clean and then make again.
