[asterisk-users] dahdi kernel module

[Greg Woods]

Does anyone know if there are any plans to update the dahdi-linux kernel
module code? It no longer compiles with recent kernels, and the last
release of dahdi-linux appears to have been around March of 2016. I am
currently running 4.6.3-300.fc24.x86_64 (on a Fedora system obviously) and
the dahdi-linux-complete-2.11.1+2.11.1 release builds and runs under this
kernel, but if I try to build it under any Fedora kernel more recent than
this, I get:

[root at worldsys dahdi-linux-master]# make

(This particular run was using the master download from github, but the
results are the same if I try to build the 2.11.1+2.11.1  release from
Digium's downloads site).

If I can't find a way around this, my only options are to junk a $600
telephony card (I shudder to think how much it would cost to replace it now
with one that has a maintained driver) or keep running a non-updateable
kernel.

Thanks,
