[Qemu-devel] [PATCH 00/14] configure: --with-confsuffix option

[Qemu-devel] [PATCH 00/14] configure: --with-confsuffix option

[Eduardo Habkost]

This series is the third version of the --confsuffix/--confdir changes I have
submitted before. Now it does two interface changes:

 - Changes --datadir meaning to match Autoconf convention
   (meaning that it should point to /usr/share, not /usr/share/qemu).
   NOTE: this breaks compatibility.
   I don't know of anybody who uses that option today. Neither Fedora, Debian,
   Arch Linux, Gentoo, or FreeBSD use it[1].
 - Add --with-confsuffix option, to allow the /etc/qemu and /usr/share/qemu
   directories to have a different names.

[1] http://article.gmane.org/gmane.comp.emulators.qemu/142924

Most of the patches are variable renames and cleanups. The actual changes are
only on the last 2 patches.

First, internal configure variables are renamed, without changing
config-host.mak:

  configure: rename $datadir to $qemu_datadir
  configure: rename $docdir to $qemu_docdir
  configure: rename $confdir to $qemu_confdir

Then create_config gets ready for config-host.mak variable renames
(Qemu-specific directories will now have a "qemu_" prefix):

  create_config: separate section for qemu_*dir variables

Then, variables are renamed on config-host.mak and Makefiles:

  config-host.mak: rename datadir to qemu_datadir
  config-host.mak: rename confdir to qemu_confdir
  Makefile: use $(qemu_confdir) instead of $(sysconfdir)/qemu
  config-host.mak: rename docdir to qemu_docdir
  config-host.mak: remove CONFIG_QEMU_SHAREDIR
  config-host.mak: reorder variables a bit

Then old code on create_config is removed:

  create_config: remove *dir block
  create_config: simplify prefix=* block, remove CONFIG_QEMU_PREFIX

Finally, the user-visible changes:

  configure: change meaning of --datadir to Autoconf convention
  configure: add --confsuffix option

[Qemu-devel] [PATCH 01/14] configure: rename $datadir to $qemu_datadir

[Eduardo Habkost]

The variable is used for the qemu-specific directory and has a different
meaning of the autoconf "datadir" variable (that's used for the
$prefix/share directory, not for $prefix/share/PACKAGE).

This doesn't change behavior or interfaces, it's just an internal
variable rename.

[Qemu-devel] [PATCH 02/14] configure: rename $docdir to $qemu_docdir

[Eduardo Habkost]

The autoconf "docdir" variable is used for the program-specific
subdirectory, but anyway it's better to make it clear that the variable
is used for the qemu-specific subdirectory path.

There's no "confdir" variable on Autoconf, but it's good to make it

$sysconfdir.

[Qemu-devel] [PATCH 04/14] create_config: separate section for qemu_*dir variables

[Eduardo Habkost]

The generic *dir section will eventually go away and be replaced with
qemu_* section. By now, both sections will be kept, while the variables
get renamed on config-host.mak.

With this patch, a XXXdir variable will become a CONFIG_QEMU_XXXDIR
define, and a qemu_XXXdir variable will become CONFIG_QEMU_XXXDIR as
well (instead of becoming a CONFIG_QEMU_QEMU_XXXDIR define).

[Qemu-devel] [PATCH 05/14] config-host.mak: rename datadir to qemu_datadir

[Eduardo Habkost]

Autoconf concept of "datadir" is supposed to be "$prefix/share", not
"$prefix/share/PACKAGE", so using datadir for the Qemu-specific
directory is confusing.

The current C code that uses CONFIG_QEMU_DATADIR should be safe, as now
create_config generates the same #define name (CONFIG_QEMU_DATADIR) for
both "datadir" and "qemu_datadir" variables.

[Qemu-devel] [PATCH 06/14] config-host.mak: rename confdir to qemu_confdir

[Eduardo Habkost]

$confdir is a confusing name, as it's not clear if it's "the system
config dir" or "the Qemus-specific directory inside the config dir".
$qemu_confdir makes it more clear.

The current C code that uses CONFIG_QEMU_CONFDIR should be safe, as now
create_config generates the same #define name (CONFIG_QEMU_CONFDIR) for
both "confdir" and "qemu_confdir" variables.

[Qemu-devel] [PATCH 11/14] create_config: remove *dir block

[Eduardo Habkost]

Now only the qemu_*dir variables will become #defines. The other
directory names aren't used by the C code.

That means the following #defines won't be available in C code anymore:

 - CONFIG_QEMU_BINDIR
 - CONFIG_QEMU_LIBDIR
 - CONFIG_QEMU_INCLUDEDIR
 - CONFIG_QEMU_MANDIR
 - CONFIG_QEMU_SYSCONFDIR
 - CONFIG_QEMU_LIBEXECDIR

The following #defines are going to be kept because they are handled by
the qemu_* block on create_config:

 - CONFIG_QEMU_CONFDIR
 - CONFIG_QEMU_DATADIR
 - CONFIG_QEMU_DOCDIR

This one will be kept because it is set directly by ./configure:

 - CONFIG_QEMU_HELPERDIR

This patch keeps the 'prefix=*' (CONFIG_QEMU_PREFIX) pattern because
other variables may use $prefix on their config-host.mak definitions.
The remaining code will be simplified on a further patch.

Autoconf uses --datadir for the /usr/share directory, not the
program-specific subdirectory inside /usr/share. This changes configure
to match autoconf behavior.

Note that this will break compatibility with existing build scripts.

[Qemu-devel] [PATCH 14/14] configure: add --confsuffix option

[Eduardo Habkost]

This will allow the user to make Qemu use a different subdirectory name
inside $datadir and $sysconfdir, instead of "/qemu".

This does not change anything because the next line is

  confsuffix=""

The subject was not adjusted, perhaps you can send a v2 of this patch only?
