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

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

[Juan Quintela]

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.

Juan Quintela (20):
  Make vnc configure options less verbose.
  Use the same structure for list of libs in curses and pthread
  Add feature configure help
  Add error message for feature not found
  Add brlapi to new feature convencion
  Add vde to new feature convencion
  Add vnc_tls to new feature convencion
  Add vnc_sasl to new feature convencion
  Add curses to new feature convencion
  Add curl to new feature convencion
  Add pthread to new feature convencion
  Add nptl to new feature convencion
  Add bluez to new feature convencion
  Add build_docs to new feature convention
  Rename build_docs to docs
  Add sdl to new feature convention
  Add fdt to new feature convention
  Add xen to new feature convention
  Add kvm to new feature convention
  Add sparse to new feature convention
