asterisk users - Apr 2012 - dahdi versions before 2.5 compilation error and ubuntu

Hi All;

It look like DAHDI versions that before 2.5 have a problem to be compiled on
ubuntu, can someone check below and advise me how to fix this?

The output of the uname -a is:

Linux House 3.0.0-17-server #30-Ubuntu SMP Thu Mar 8 22:15:30 UTC 2012 x86_64
x86_64 x86_64 GNU/Linux

I am trying to install DAHDI on ubuntu and I faced a problem if I am compiling
versions before 2.5, but if I tried 2.5 and newer then it is working fine.

The error is:

make[2]: Entering directory `/usr/src/linux-headers-3.0.0-17-server'
  CC [M] 
/usr/src/dahdi-linux-complete-2.4.0+2.4.0/linux/drivers/dahdi/dahdi-base.o

Why not use DAHDI 2.5.0.2 then? What reason do you have for staying
on 2.4?

You are attempting to build dahdi-linux 2.4.0. The problem that you
are describing was addressed in commit r9721 "dahdi: Experimentally
remove dependency on the Big Kernel Lock." [1] and is in 2.4.1. So I
believe you should be good to go with dahdi-linux 2.4.1.2.

[1] http://svnview.digium.com/svn/dahdi?view=revision&revision=9721

Keep in mind that the 2.4 branch isn't actively maintained so
whether or not it continues to get back ported patches as the linux
kernel interfaces change is going to be ad-hoc at best.

Cheers,
Shaun
