Makefile: how to avoid specifying all targets manually

I wrote this Makefile:

all: clean basedemo.exe

clean:
  rm -f *.exe

%.exe: %.s
  vasmm68k_mot -kick1hunks -Fhunkexe -o $@ -nosym $<

My goal would be to compile every .s file in the current folder to a separate .exe.

Right now, I have to append the new .exe file name to the line: all: clean basedemo.exe new_file.exe

Is there a way to avoid having to do that?

Thank you

I tried using a wildcard:

all: clean $(wildcard *.exe)

But when I run make all only the clean recipe runs.

>Solution :

$(wildcard *.exe) searchs for existing .exe files, but they do not exist yet when you run make.

What you can do is to find all .s files and substitute their extension to .exe:

FILES_S:=$(wildcard *.s)
FILES_EXE:=$(FILES_S:%.s=%.exe)

all : clean $(FILES_EXE);
