Question

I have many file with extension .cpp

f001.cpp
abc.cpp
...

I try compile any file with this

%.cpp:
        g++ -o $* $*.cpp

but I get

make: *** No hay objetivos.  Alto.

Answer 1

Does this work?

f001.o:

%.o: %.cpp
        g++ -o $@ $<

EDIT:

Good! Now try this:

OBJETIVOS = f001.o abc.o def.o ghi.o

todos: $(OBJETIVOS)

%.o: %.cpp
        g++ -o $@ $<

There is one problem here. Usually abc is the executable binary file, and abc.o is the object file. You are building executable files, but calling them abc.o. If you want them to be executable files, it would be better to call them abc.
