[Freeswitch-users] Help needed about building snd_dummy with the dummy.c in skypopen

Hi,
I am trying to follow this wiki:
http://wiki.freeswitch.org/wiki/Skypiax_Skype_Endpoint_and_Trunk
to setup FS and Skypopen on Ubuntu 8.04(64bit server inside virualbox).

There is one step asks me to build snd_dummy:
http://wiki.freeswitch.org/wiki/Skypopen_Skype_Endpoint_and_Trunk#ALSA_and_the_custom_snd-dummy
The section is like below:
 Ubuntu, Debian

Note, Ubuntu may have alsa sound drivers installed at /lib/modules/<your
kernel version>/ubuntu/sound/..., you may need to remove the dir to allow
modprobe search from the default place: /lib/modules/<your kernel
verision>/kernel/sound/ (don't forget to rerun /sbin/depmod after removing
the old sound directory. Eg: /sbin/depmod -a 2.6.24-24-server).

./configure --with-redhat=no \
--with-cards=dummy,usb-audio,hda-intel,hrtimer,rtctimer \
--with-card-options=all
make && make install

After the first *make && make install*, copy
mod_skypopen/configs/alsa/dummy.c to alsa-driver-1.0.20sound/drivers/dummy.c
.

make && make install #again :)

The problem is after I did all of them, when I entered modprobe snd_dummy,
it always crashed and returned as "killed" on my terminal, I could see it
dumped out a huge block or data(numbers, etc) on the host but don't
understand the meaning. While if I used the original dummy.c inside
alsa-driver-1.0.20, it worked fine.
Besides, the default ubuntu installation doesn't include kernal dev and
source, so I did one more step(or it cannot build alsa).

Did anyone try the same and get it working?

Thanks!
Jian
