Hi All.

I'm struggling with writing a relatively complex makefile, and right
now I'm trying to set some variables based on a target. Can anyone
lend some insight?

Let's say I have a target named sfp400ma.lib. To make this particular
target (there are many targets, all differing by a little bit), I
need to set some variables that will be passed to the compiler on its
command line.

1) Based on just the "sfp" part, I want to set a variable. This I do like this:

        sf%.lib : VAR1 = SOMETHING

2) Based on just the "ma" part, I want to set another variable. This
I do like this:

        %ma.lib : VAR2 = SOMETHING_ELSE

I'm having difficulty figuring out how to write the makefile so that
_both_ of these variables are assigned when I make the target:

        make sfp400ma.lib

What I'm faced with is make only pattern-matches the first time, and
leaves the second variable undefined. I suspect there's some way to
strip various characters out of the target name and set variables
based on that, but after reading the GNU make docs I still can't see
how it's done.

Any ideas?

Thanks,
