Hello,
I have written a Makefile (.am, but this is a Make
issue), containing:
--------------------------
description:
@echo "a short description here containing
@PACKAGE_VERSION@ and other stuff available only at
maketime (like $(DESTDIR))"
description-long:
@echo "a multiline"
@echo "description"
@echo "here, with $(DESTDIR) and other
maketime stuff"
.SILENT: description description-long
--------------------------
I later use these targets as a workaround for the
unportable use of define to create variables
containing newlines:
install-data-hook:
$(MAKE) -s description >>
$(DESTDIR)/$(PACKAGE_DESCRIPTION_FILE)
$(MAKE) -s description-long >>
$(DESTDIR)/$(PACKAGE_LONG_DESCR_FILE)
This works fairly well if I just run
$ make description
on the command line, but when run from the
install-data-hook I get:
make[n]: Entering directory `foo'
make[n]: Leaving diretory `foo`
messages that cripple my output file.
I thought that the -s option should be stronger than
the submake implicit -w option:
[quote `info make`, about the -w option]
Normally, you do not need to specify this option
because `make' does
it for you: `-w' is turned on automatically when you
use the `-C'
option, and in sub-`make's. `make' will not
automatically turn on `-w'
if you also use `-s', which says to be silent, or if
you use
`--no-print-directory' to explicitly disable it.
[quote end]
I imagine that probably --no-print-directory fixes the
thing, but I have not even tried it, because -s is
portable (POSIX), but --no-print-directory is not, and
is thus out of question for my program.
If the idea of fixing the thing is generally accepted,
I can work on a patch.
Thanks,
Claudio
