No. VPATH isn't used until long after the makefiles are all read in;
whatever value it has at the end of the parsing is the value it will
have for all targets.
You could do one of two things: use the VPATH variable as a
target-specific (or pattern-specific) variable (I think this will work).
No, it doesn't appear to work. I tried this, where the files /foo/a.c
and /bar/a.c exist:
all : a.o1 a.o2
a.o1 : VPATH:=/foo
a.o1: %.o1 : %.c
echo $@ $^
a.o2 : VPATH:=/bar
a.o2: %.o2 : %.c
echo $@ $^
Which gives the error message:
make: *** No rule to make target `a.c', needed by `a.o1'. Stop.
Or, use a more restrictive pattern for vpath, so instead of:
vpath %.c ...
you do something like:
vpath $(prefix)/%.c ...
where the prefix variable restricts the values to match the "current"
location, whatever that is.
That doesn't seem to work either.
