This is a minor comment, but I would have expected to see Wine in either
of those sub-menus, instead of "Miscellanous":
- Audio and video applications
- Graphic libraries and applications
I think it would fit nicely alongside X.org.
But this is really, really minor! ;-)

Well, x86_64 is not the same as i386 in Buildroot. So this makes Wine
really available only on i386 (the 32-bit variant).
Is that what you really wanted to do?
Otherwise, maybe change to:
depends on BR2_i386 || BR2_x86_64

Formatting is a bit off. Try to get lines all about the same width.

It looks like the official URL is on sourceforge, rather than using a
git snapshot, as seen on: https://www.winehq.org/download
Location Description
sourceforge.net Our official source release site.
source.winehq.org/git For the latest development version.
So:
WINE_SITE = http://downloads.sourceforge.net/project/wine/Source
> +WINE_LICENSE = LGPLv2.1+
> +WINE_LICENSE_FILES = COPYING.LIB
Adding the file LICENSE would be good, too. LICENSE.OLD is not
necessary, though.
> +WINE_INSTALL_TARGET = YES
Unneeded, that's the default.
> +WINE_DEPENDENCIES = host-wine
> +HOST_WINE_DEPENDENCIES = host-bison host-flex
So, you do not need host-bison or host-flex to build the target variant?
After looking at configure.ac, yes you do. So:
WINE_DEPENDENCIES = host-bison host-flex host-wine
should be enough, no need to specify HOST_WINE_DEPENDENCIES, they are
derived from the target dependencies, so will end up with the correct
value.

So, I've had a look at what --{en,dis}able-win64 means. From what I
understand, if you --enable-win64, you get a 64-bit-only build,
incapable of running win32 binaries. Conversely, if you --disable-win64,
you get a 32-bit-only build, incapable of running win64 binaries.
Right?
That's a bit unfortunate, since on a 64-bit target, it might well be
legit for a user to want to run win32 *and* win64 binaries. But it is
not possible to ahve Wine build both at the same time. Pity... :-(

We prefer positive logic:
ifeq ($(BR2_TOOLCHAIN_EXTERNAL),y)

> +endif
Sorry, I still do not understand what happens here...
I commented those lines, and I observed this:
[...]
checking for i586-buildroot-linux-gnu-gcc... /home/ymorin/dev/buildroot/O/host/usr/bin/i686-pc-linux-gnu-gcc
[...]
checking for i586-buildroot-linux-gnu-ar... /home/ymorin/dev/buildroot/O/host/usr/bin/i686-pc-linux-gnu-ar
checking for i586-buildroot-linux-gnu-ranlib... /home/ymorin/dev/buildroot/O/host/usr/bin/i686-pc-linux-gnu-ranlib

[...]
checking for i586-buildroot-linux-gnu-readelf... /home/ymorin/dev/buildroot/O/host/usr/bin/i686-pc-linux-gnu-readelf
[...]
... which seems pretty much what we would expect.
Oh... Then it fails at build time, because of that fscking wrapper to
gcc. Damn.
Ok, so here it goes:
- wine uses a wrapper around gcc
- at configure time, it uses the value from --host and passes it as-is
to the gcc wrapper
- the gcc wrapper uses that variable to generate the gcc name
and we end up with errors like:
../../../host-wine-1.6.2/tools/winegcc/winegcc -b i586-buildroot-linux-gnu [...]
winebuild: cannot find suitable name lister
Bummer... :-(
But I found an alternative that I like a bit more:
# Wine uses a wrapper around gcc, and uses the value of --host to
# construct the filename of the gcc to call.
# But for external toolchains, we may have a discrepancy between the
# tuple, GNU_TARGET_NAME, that we construct from our internal
# variables, and the gcc prefix for the external toolchain.
# So, we have to iverride whatever the gcc wrapper believes what the
# reall gcc is named, and force the tuple of the external toolchain,
# not the one we compute in GNU_TARGET_NAME.
ifeq ($(BR2_TOOLCHAIN_EXTERNAL),y)
WINE_CONF_OPTS += TARGETFLAGS="-b $(call qstrip,$(BR2_TOOLCHAIN_EXTERNAL_PREFIX))"
endif
This allows us to keep our stndard --host value, and just overrides the
-b option passed to the gcc wrapper.
Care to test that on your side, please?
[--SNIP--]
Ok, tested with ths defconfig, and the few tweaks I mentioned above.

Yann E. MORIN.
