I have the following Makefile:
foo: bar
@echo While building $@ MACRO = ${MACRO}
foo: MACRO += foo_specific
bar:
@echo While building $@ MACRO = ${MACRO}
bar: MACRO += bar_specific
MACRO = common
I would expect to get the output:
While building bar MACRO = common bar_specific
While building foo MACRO = common foo_specific
but instead I get:
While building bar MACRO = common foo_specific bar_specific
While building foo MACRO = common foo_specific
Is this a bug or am I misunderstanding how target specific variables
work.
The real use case is when I have a Makefile that is building both an
shared object and an executable that uses it. I want to factor LDLIBS
into common libraries that both use and specific libraries that are only
for the shared object or the executable. But due to this behavior, I
can't have the executable dependent on the shared object.
Thanks,
samuel
