Sure.. No problems.. Very easy to repro for me with the following.. Invoke
make using 'make release' and you *should* see :
Makefile:10: *** Mode WAS defined properly!. Stop.
However, that is not the case w/ Make 3.81.. Below are the two Makefiles
to try this out with :
Contents of Makefile:
===================================
foo = foo
bar = bar
include Makefile-aliases.mak
ifndef mode
mode = bar
$(error mode NOT defined properly!)
else
$(error Mode WAS defined properly!)
endif
===================================
Contents of Makefile-aliases.mak
===================================
.PHONY: release
release: all
ifneq ($(filter release,$(MAKECMDGOALS)),)
mode = foo
endif
===================================
Just keep in mind that the conditional above (ifndef) controls
reading a secondary Makefile in my real probkem scenario.. It appears
that it eventually sets 'mode=bar' but not in the proper time frame
for the conditionals above.. You can see this below by the output from
'make -p release | grep mode' :
Makefile:8: *** mode NOT defined properly!. Stop.
mode = bar
mode = foo
It doesn't seem to matter if I used variables w/ := vs. = either.. If
there's something obvious I've missed, please let me know... Thanks!
