Problem building WANPIPE Drivers

Asterisk Asterisk Hardware
1

Good day,

I’m in the process of building a new Asterisk 18-LTS system on Ubuntu 22 (Jammy Jellyfish). I found and installed preconfigured packages for DAHDI and LIBPRI, but I’m using the Sangoma A104d quad T1 card so I need the WANPIPE drivers as well.

This is where I ran into problems. The WANPIPE install starts OK, and gets most of the way through, then I get this:

I’m no programmer, just a guy trying to get a new install to work. Anyone got an idea on this one?

Thanks.

Hi,
in file patches\kdrivers\src\wanrouter\af_wanpipe_src.c replace current->state with current->__state on line 603 and 622. Run script again.

Yes, I’ve seen it with WRITE_ONCE as well but not sure what impact that has.

Here is a more complete fix for newer kernels (>= 5.14) contributed by a community member: phreakscript/af_wanpipe.diff at master · InterLinked1/phreakscript · GitHub
