Subject: Re: [Bluez-users] btsco kernel make (simple error I'm sure)

Christopher,

Build the kernel first. Make sure you select at least one alsa driver
inside the kernel so you'll have all the necessary support for the btsco
driver.

After ./bootstrap && ./configure

I cd into the /kernel directory..

and running make gives this error..

(I've read the README, all links referring to the README and a quick
tutorial on rebuilding kernel and kernel modules.) Nothing really jumps
out as the answer unless I should have this stuff in a different
directory? (There are a couple fixdep on my computer, but I'm not sure
if I should ln -s it somewhere..) Sorry for the newbie question..

Subject: Re: [Bluez-users] Missing sndmagic.h for btsco kernel patch

Christopher,

We are now working with v2.6.10 and a kernel module you can get from
cvs. We don't patch the kernel under the current scheme. see
bluetooth-alsa.sf.net

Unfortunately, using a vendor kernel is difficult with btsco. We're
having to track fairly recent kernels because things keep changing in
the (stable!) kernel releases and we don't have the resources to
maintain for multiple kernels :(

Subject: [Bluez-users] Missing sndmagic.h for btsco kernel patch

Trying to get my bluetooth headset to work and so I'm going through the
steps..

I applied the kernel-2.6.7-8.24-08-04.patch for the btsco driver, but I
realized I'm missing sndmagic.h file. I'm running Suse 9.2 with the
alsa-devel installed.. I think I noticed that RH/Fedora had a rpm
alsa-lib-devel that included this file, but wasn't sure if I could just
ignore this missing file, most likely not, or if I should give rpm in
the RH/Fedora a shot. Or is this something simple like copying the
missing file? First post and help is appreciated.
