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’

One thought on - dahdi versions before 2.5 compilation error and ubuntu

  • Why not use DAHDI 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

    [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.
