Hello,
I've encountered a possible error in a generated 'po/Makefile' when switching
from gettext 0.18 to 0.19.
I hope 'getetxt' is the relevant mailing list, but if the culprit is a
different autotools part, please let me know.
When using gettext-0.19 in a project,
then running 'configure && make' on FreeBSD 9.3 (which uses some old version of
non-gnu make),
make will fail with "error expanding embedded variable".
It can be demonstrated with this contrived example Makefile:
====
srcdir = .
PACKAGE = datamash
POFILESDEPS_ = $(srcdir)/$(DOMAIN).pot
POFILESDEPS_yes = $(POFILESDEPS_)
POFILESDEPS_no =
POFILESDEPS = $(POFILESDEPS_$(PO_DEPENDS_ON_POT))
DOMAIN=$(PACKAGE)
POTFILES = src/datamash.c
all: $(POTFILES)
$(POTFILES): $(POFILESDEPS)
====
It seems that 'PO_DEPENDS_ON_POT' is not defined anywhere, and so expanding it
fails with this version of 'make'.
Note that it doesn't fail with GNU Make, or with the 'bmake' found on FreeBSD
10.1.
Adding 'PO_DEPENDS_ON_POT=no' solves the issue.
Perhaps by default it can defined as 'no', instead of non-existing/empty
variable?
thanks,
