This may be a little frivolous, but in GNU Octave's top-level
Makefile.am, we override the check: target:
http://hg.savannah.gnu.org/hgweb/octave/file/1bfca2bbea8b/Makefile.am#l106
However, in the generated Makefile, this produces a warning:
Makefile:2354: warning: overriding commands for target `check'
Makefile:1948: warning: ignoring old commands for target `check'
because the generated Makefile contains these lines:
## Standard target
check: $(BUILT_SOURCES)
$(MAKE) $(AM_MAKEFLAGS) check-recursive
## Overriden target
check: all
$(MAKE) -C test check
I would like to silence that warning. It clutters my compilation
buffer when I'm in Emacs and want to quickly jump to the first error
or warning with C-x `. It would suffice if I could make the check:
target empty. Can you please explain under what conditions the check:
target actually has a script involved? I tried making a minimal
example of my own with Automake, and it produced something like this:
...
check: check-recursive
all-am: Makefile config.h
...
i.e. an empty target. So I can override check: without getting a
warning. When does this happen? When is the check: target empty and
when does it actually have a command in there?
TIA,
