Kconfig changes in /hg/v4l-dvb caused dvb_usb_cxusb to stop building

Kconfig changes in /hg/v4l-dvb caused dvb_usb_cxusb to stop building

[Peter Baartz]

HI,

I have Dvico dual 4 DVB-T card (rev. 2), which  wants to use the
module dvb_usb_cxusb.

When i attempt  build http://linuxtv.org/hg/v4l-dvb, make no longer
builds cxusb...

The  Kconfig: commits appear to have caused this... i.e. cxusb build
fine when using  "changeset 10834	277d533e87cd"  (it's just prior  to
Kconfig: commits )  from hg/v4l-dvb.

Thanks,
Peter

Peter,

This seems to be caused by a bug at the out-of-tree building system. I'm
currently checking what's going wrong.

Cheers,
Mauro

Yesterday I grabbed a fresh clone of v4l and compiled drivers for my
nexus-s.  Only that none of the required frontend modules were enabled
automatically as they should be when I selected AV7110.  I had to
manually go enable them by hand.  Luckily I knew which ones were
needed but I'm sure a ton of users have no clue.

Hopefully, it should be fixed right now. I did a one-line change at the scripts
that does the .config initialization. At least, on my tests, everything seems
to be fine right now with -hg.

I just grabbed a fresh clone (7cfb5386b66f tip) to see and it's still
broken.  Everything was enabled in menuconfig by default but
deselecting everything and then enabling AV7110 back still isn't
-M-'ing the required frontends.

It won't mark they with M, if you keep enabling DVB_FE_CUSTOMISE, since 
this Kconfig var allows manual override over the frontend modules.

In order to just select what av7110 modules need, you should disable it. 
By disabling, the building system will auto-select the frontends that are 
needed by a full av7110 support.

This is what I get here if I disable all video devices but av7110:

$ cat linux/drivers/media/dvb/frontends/Makefile | perl -ne 'if 
(m/CONFIG_([A-Z_\d]+)/) { print "$1\n" }' >/tmp/fe; grep -f /tmp/fe 
v4l/.config

CONFIG_DVB_L64781=m
CONFIG_DVB_VES1820=m
CONFIG_DVB_STV0297=m

Cheers,

As reference, this is the complete .config, where I've disabled all 
V4L/Radio/DVB adapters, keeping just av7110 and letting the building 
system to auto-select the tuners and the frontends:

Ok, tried again and it's as you said.  I assumed the behavior of
DVB_FE_CUSTOMISE hadn't changed but it appears it has.  Although, I
think the previous behavior is still better having the required
modules as locked -M-.  At least then the user has some kind of
control over what modules are built without risk of disabling
something he needs.  What was the logic behind making this change?

That's one thing I don't understand... Why an os that prides itself on
user-customization seems to always be introducing ways to limit the
user.
