pattern matching

[Christopher G.Morlier]

Hi,

I am trying to compile a source file from another directory into an object 
file in the current directory.  I have used gcc to create the dependencies 
file, and have a dependency of the form:

file.o: /dir/subdir/file.c /dir/include/header.h

After some debugging, the implicit rule seems to be executing however the 
compiler complains that it cannot find file.c.  So I overrode the implicit 
rule with my own pattern rule:

%.o:%.c
        echo $<
        echo $*

It appears from the output that the directory information is not being 
included on .c file.  Why is this?  Any work arounds?

This is the first time I am attempting to make into a different directory, 
so any pointers or examples would be appreciated.

BTW, I am using Make version 3.79.1 under Cygwin.  Unfortunately, the 
compiler for my target (TI C6x DSP) only runs under windows.

Thanks for your help,
Chris
