mk: WITH_FOO=no now generates a warning

Authored by imp on Mon, Jun 7, 8:00 PM.



Many people are used to gnu configure's behavior of changing
--with-foo=no to --without-foo. At the same time, several folks have
WITH_FOO=no in their config files to enable this ironic form of the
option because of an old meme from IRC, a mailing list or the forums (I
forget which). Add a warning to allow to alert people w/o breaking POLA.

If you put -D at one place you should put it in the other.
But I think that we shouldn't .warning with -D here, as we have redirected people to use src.conf for a long time now.

sure. updated comment


There is a '-' that shouldn't be there :)


Doesn't WITHOUT_FOO=<yes> perpetuate the wrong idea?


What if they have WITHOUT_FOO=no?

better message


changed it to be generic.


I'm unsure on this point. WITHOUT_FOO=yes and WITHOUT_FOO=no both make sense to enable it depending on your world view, which is likely informed by your native language is. In Spanish, double negatives are still negative, so that construct makes sense and =yes is weird. English speakers, on the other hand, would think WITHOUT_FOO=no is negating it so it should enable.

WITH_FOO=no, though, never makes sense and is a common idiom for WITHOUT_FOO in other contexts...

So I'm unsure what to do about the WITHOUT_FOO case.
