Re: How to specify the location for .o files in makedepend?

[lanxue]

Thanks for the replies. I tried this:

        cd $(TEST)/src;
        makedepend -Y $(CFLAGS) -p $(TEST)/obj *.c

In which $(TEST) gives the full path of the parent directory. But got
errors that can't open *.c. I also tried to specify the src file name, eg,
mytest.c, but still the file can't be found. I suspect "cd" might not work
in here.

Thanks,

Lan
