Make: Loop to handle several object files listed in a file separately

[Peter Bolz]

Hello,
does anyone know how to get a loop depending on the filenames
listed in a file, so that each file listed there can be handled
individually?

This is to call the library builder which has to be done separate for each
object file.

----- File list e.g. in file File1.X:
LIBOBJ= \
nscanf.o \
clock.o \
chksmadj.o \
netconf.o \
httest.o \

----- Tools:
LIBR = $(PATH_CTOOL_UNIX)/ax

----- Rule:
libgen:
@echo xxx Create lib xxx
rm -f liby.a
$(foreach objfile, $(LIBOBJ), ???????????????????????????????????)
@echo xxx Ready lib creation xxx

Thank you!

Hi,
I am not sure that I understand your problem but if you just want to
read a list of dependencies from a file and then compile a library from
these something like the following should work:

# SNIP
LIBOBJ=$(shell cat File1.X)

liby.a: $(LIBOBJ)
rm $@
for o in $(LIBOBJ) ; do \
apply_treatment $$o ; \
done;

libgen: liby.a

# SNAP

I believe make has already some library compilation functionality, but I
have not yet studied it.

Cheers,
Arnd.

Hello Arnd,

thanks for your proposal. I'll test it.
First try failed, but give me some time.
