I was in agreement with that line of argument while the patch was
discussed, and I still think the above is true.
And if the primary thing we want to address with this patch is the
build breakage for those who do not have tclsh nor msgfmt, perhaps
it is a more direct fix to update this part in gitk/Makefile:
## po-file creation rules
XGETTEXT ?= xgettext
ifdef NO_MSGFMT
MSGFMT ?= $(TCL_PATH) po/po2msg.sh
else
MSGFMT ?= msgfmt
ifneq ($(shell $(MSGFMT) --tcl -l C -d . /dev/null 2>/dev/null;
echo $$?),0)
MSGFMT := $(TCL_PATH) po/po2msg.sh
endif
endif
There is an identical copy-and-pasted copy of this in
git-gui/Makefile, and both of them silently assume that TCL_PATH
points at something usable when msgfmt is not available.
Perhaps the "else" part of the above should become a bit more
careful, something along the lines of...
else
MSGFMT ?= msgfmt
- ifneq ($(shell $(MSGFMT) --tcl -l C -d . /dev/null 2>/dev/null;
echo $$?),0)
- MSGFMT := $(TCL_PATH) po/po2msg.sh
- endif
+ MSGFMT_DRYRUN = --tcl -l C -d . /dev/null 2>/dev/null
+ ifneq ($(shell $(MSGFMT) $(MSGFMT_DRYRUN); echo $$?),0)
+ ifneq ($(shell $(TCL_PATH) po/po2msg.sh $(MSGFMT_DRYRUN); echo
$$?),0)
+ MSGFMT := $(TCL_PATH) po/po2msg.sh
+ else
+ $(error "no usable msgfmt to build gitk; set NO_TCLTK
perhaps?")
+ endif
endif
endif
Another reason why I think the Makefiles in gitk and git-gui
projects are better targets for the fix is because they are designed
to be independent projects. We should be able to do
cd git-gui && make
in our tree, but an update to our top-level Makefile does not help
those people.
