Re: Passing directory to submake

[Russell]

Hi,

I thought i'd solve it using a pattern rule
in each subdirectory:

%.o: %.c %.h
  $(CC) $(CFLAGS) -o $@ $<

However, when a file matching %.o does not exist,
make gives an error: *** No targets. Stop.

How can i get 'make' do the command and create
that .o file?
