It seems that there are only some warnings but no error. Please check if there is already an emu in ./build path.

Again I make verilog and problem fixed. Is it neccesary each time we change code, both make verilog and then make emu?

No, I think make emu is enough... make should arrange the dependency automatically.

The before log is not an error. make thinks that there is no file modified and emu is up-to-date, so it does not need to do anything. Please make sure that you did modify some source files.
