[Qemu-devel] [PATCH 00/20] Make --enable-foo a requirement

[Juan Quintela <quintela@redhat.com>]

Hi

--enable-foo in current qemu just means to enable foo if it founds it, otherwise just
not enable it silently.  This patches changed everything to use the convention:

  * foo="no", feature will only be used if --enable-foo arg is given
  * foo="", feature will be searched for, and if found, will be used
  * foo="yes", this value vill only be set by --enable-foo flag.
                   feature will searched for, if not found, configure exits with error

It is important for distributions. Otherwise, if something is not installed, things
don't fail to compile, just are disabled.

Once there, add --enable-foo for all things that already have --disable-foo and make sense.
There are still a few bits that donot' have both --enable-foo/--disable-foo, but they are
the minimal things.

kvm: the extra error message is only given if you do a --enable-kvm, by default, if kvm
is not found, it just fails, as everything else.

Questions:
- sdl: anyone really uses sdl + static?  I am not sure that they compile correctly, and
  they are just complicated.
- Do we want to sort things on the file?  I.e. libraries detection toguether, features
  detection together, ....  Just new they are a completely mess, completely unsorted
  as far as I can see.

Later, Juan.
