pattern rule prerequisites?

[Andre Merzky]

Hi, 

trying to get used to the pattern rules, I met following problem:

libs = liba.so
liba_objs = a1.o a2.o a3.o

lib%.so:
        ld -shared -o $@ $(lib$*_objs)


That looks like what I wont (dont ask why ;-), but now of course I
would like to specify the liba_objs as prerequisites to the lib%.so
pattern.  How do I do that?  Following seems to fail:

lib%.so: $(lib%_objs)
        ld -shared -o $@ $(lib$*_objs)

As far as I understand the pattern match is done _after_ _all_ vars
and functions are expanded - so $(...) just gets not expandeda after
the match.  

This also fails:

lib%.so: $(lib$*_objs)
          ld -shared -o $@ $(lib$*_objs)

probably for the same reason ;-)

Thanks for any hint, 

  Andre.
