@adi@f.adi.onl I can try. I know some things about make at least.

@adi@f.adi.onl Ugh sorry for not replying. If the file list is dynamic, usually you use something like autoconf to generate the Makefile. I’ve also used wildcards in the past and that works okay. You should be able to use shell commands to populate the file list.

@adi@f.adi.onl What about this one?

SRCFILES = $(wildcard *)
# remove existing *.gz (actually doubles entries)
CLEANSRC = $(SRCFILES:.gz=)
DSTFILES = $(addsuffix .gz, $(CLEANSRC))

%.gz: %
	gzip -c  $< > $<.gz

all: $(DSTFILES)

You must not have subdirectories in that folder, though.
