I'd like to do a Makefile that runs either with gnumake or makepp that packs all the files under given directiories:
DIRS:=$(shell find . -mindepth 2 -maxdepth 2 -not -name mp3 -not -name ".*" -type d)
PACKAGES = $(DIRS:%=%.npk)
all: packages
packages: $(PACKAGES)
%.npk: %/*
npack c $@ @^
.PHONY: all packages
the problem is that there's no such thing as %/* in the dependencies. I need the targets (X.npk) to depend on every file in directory X, but I don't know what the files are when I write the Makefile, 'cause they're generated later.
An example:
./dirA/x
./dirA/y
./dirB/e
./dirB/f
I'd like to create ./dirA.npk (depending on x,y), ./dirB.npk (e,f) There's nothing I know about the dirs or the files in advance except that the find used in the 1st line finds all the dirs.
This is the solution I found: it is based on the makedepend idea, with some "meta" scripting. Not very nice, but works.
