I am trying to build the wl1251 driver from compat-wireless 3.3.1-1, using a separate (Android-based) kernel as a base, but I am encountering a few snags:
>From the base compat-wireless-3.3.1-1 (CCOMPILER environemnt variable is set to the toolchain directory prefix I use for ARM):

Should I be worried about the above warning? I do *not* have "CONFIG_WIRELESS_EXT" anywhere in my (android kernel) .config, but do have CONFIG_WIRELESS=y as well as CONFIG_CFG80211_WEXT=y. Also, I can't see any of the wl1251 drivers from compat-wireless (located in drivers/net/wireless/wl1251) being built at all! Am I missing something?
On a slightly different note, I also tried to use previous versions of compat-wireless - 3.1.1 as well as 2.6.39-1 - but things got even more hairy. After executing make, I got this:
make[3]: *** No rule to make target `/builddir/compat-wireless-3.1.1-1/net/wireless/db.txt', needed by `/builddir/compat-wireless-2.6.39-1/net/wireless/regdb.c'. Stop.
After the above error I just copied db.txt from wireless-regdb-2011.04.28.tar.bz2 to net/wireless, but then got this next:
make[3]: *** No rule to make target `/builddir/compat-wireless-3.1.1-1/net/wireless/genregdb.awk', needed by `/builddir/compat-wireless-3.1.1-1/net/wireless/regdb.c'. Stop.
So, again, I copied genregdb.awk from the 3.3.1-1 version of compat-wireless, but that wasn't enough, unfortunately:
WARNING: "reg_regdb_size" [/builddir/compat-wireless-3.1.1-1/net/wireless/cfg80211.ko] undefined!

The wl1251 drivers are not built here either - drivers/net/wireless/wl1251 is untouched! Any help or advice as to how can I resolve this would very much appreciated, thanks!

I've had somewhat limited success with this - I was able to build
2.6.38-2 compat-wireless by manually copying "db.txt" as well as
"genregdb.awk" to
<android_kernel_dir>//builddir/compat-wireless-XXX/net/wireless (yeah, I
created it manually) as well as forcing CONFIG_CRC7=y and
CONFIG_WL12XX_PLATFORM_DATA=y.
"make modules-install" gives me 6 modules: compat, cfg80211, mac80211,
wl1251, wl12xx_platform_data and wl1251_sdio. I "modprobe" them in that
order, but then I get this error:

I have also tried to build the latest snapshot (tried the one from 21
April 2012), but things there got a bit more messy - the ti drivers were
indeed moved to the ti/ directory, the Makefile, however, after
selecting "ti" (or any of the TI drivers - TI1251 or TI12XX) is
completely empty. I did a bit of investigation and it turns out that the
offending part of the code is in the select-driver script, which
executes "egrep WL1251|WL12XX" on the original Makefile and since the
Makefile CONFIG_* setting does not contain either of these values for
the ti/ directory (it has something like CONFIG_TI_*) that results in an
empty Makefile.
Even if I correct this and leave just the ti-related settings in that
Makefile, I am still faced with my original problem I already pointed
out above - wl1251, wl1251_sdio and wl12xx are not built - just compat,
mac80211 and cfg80211 are compiled, so I am stuck - good and proper, again.
Luciano, anyone?

No, don't worry. This is harmless if you don't use WEXT. Just remove
the CONFIG_CFG80211_WEXT from your .config and the warning should go
away.

Sometimes compat-wireless breaks, when syncing with the latest upstream
sourcers. If the newest works for you, use that. ;)

If this is a recent compat-wireless, then the wl1251 driver was moved to
drivers/net/wireless/ti/wl1251. Can you check that?

I initially used compat-wireless-3.3.1-1 as it was the latest "stable"
kernel edition released. The wl1251 drivers are in net/wireless/wl1251,
not drivers/net/wireless/ti/wl1251. That is also the case with the
latest released compat-wireless - 3.4-rc3-1.
I did a bit of hacking/tweaking, but ran into much bigger problems and
simply gave up in the end. When I looked at various compat-wireless
makefiles I saw that, somehow the inclusion of wl1251 as well as wl12xx
depends on CONFIG_CRC7 and CONFIG_WL12XX_PLATFORM_DATA being set (the
latter also depends on wl12xx, so if I wanted it included, I had to
switch to "wl12xx" instead of "wl1251"). So, I did the following:
./scripts/driver-select restore
./scripts/driver-select wl12xx
make ARCH=arm CROSS_COMPILE=$CCOMPILER KLIB=<android_kernel_dir>
KLIB_BUILD=<android_kernel_dir> CONFIG_CRC7=y CONFIG_WL12XX_PLATFORM_DATA=y
I then get the following errors:

Apparently, "pm_runtime_enabled" is defined in
include/linux/pm_runtime.h, but this is for the 3.0+ version of the
kernel - I am using 2.6.37! Something seems to be seriously screwed up!
The above is valid for all 3.x versions of compat-wireless I tried! I
was under the impression that compat-wireless is backward-compatible
with "older" kernel versions, like mine, is that not the case?!
When I tried the latest compat-wireless before 3.x (2.6.39-1) I don't
get the first error, but get the other two, albeit with modified
function names (wl1271_sdio_* instead of wl12xx_sdio_*).
In addition to the above, for some reason when I run compat-wireless for
versions prior to 3.x (I tried 2 such versions - 2.6.39-1 and 2.6.38-2)
I also get a weird error that
"<android_kernel_dir>//builddir/compat-wireless-XXX/net/wireless/db.txt
cannot be found" - the search path there is completely wrong, it should
either be <android_kernel_dir>" or
"/builddir/compat-wireless-XXX/net/wireless/db.txt" and not this weird
concatenated path containing both!
Again, this only happens with the 2 releases prior to 3.x I tried and
only when I have "db.txt" and "genregdb.awk" from 3.3.1-1 manually
copied to net/wireless. Any help?
Luciano, seeing as you work for TI, I have one more query for you, if I
may - the need for me to turn to build compat-wireless was borne out of
my continuous, *completely fruitless* and *extremely frustrating*
attempts for me to build a decent version of wpa_supplicant for my
android device, which uses the "native" TI-supplied wireless driver for
that device (tiwlan) - it proved an absolutely impossible task as the
TI-supplied driver refuses to build with wpa_supplicant which has
version any other than v5.11 (I have tried *all* released versions after
this one - 6.11, 0.7.1, 0.7.3, 1.0-rc, 1.0 as well as the latest from
git)! "Newer" TI-supplied drivers do *not* work with my TI-1251 device
at all!
Is there a decent driver for TI-1251 which could be integrated with a
relatively recent/decent version of the wpa_supplicant?
It is imperative that I build a decent version of wpa_supplicant for my
device and it is the sole reason why I have chosen this route and turned
to the Linux-based wireless stack, but unfortunately my assumption that
the process there would be more straight-forward proved to be rather
naive and my earlier optimism completely misplaced! :-(
