Trouble building dahdi with assignment from incompatible pointer type error

Hi, I’m trying to compile the latest version of dahdi-linux from git with an error involving pointer trouble:

git clone git://git.asterisk.org/dahdi/linux dahdi-linux && cd dahdi-linux && make install

This is on fedora27 with kernel-4.15.3-300

This is a problem with the compatibility between kernel-4.15.3 and the current version of dahdi-linux drivers. I would assume later kernels would also have a problem.

This is still a problem with fedora27 and kernels as recent as 4.16.3-200. Anyone else having a problem? Is there a beta version that I could try?

Why this completely broken POS is included in the repos of Ubuntu 18.04.1 is beyond me. I have spent the last 12 hours trying to get this to work. The packages installed but the dkms.conf didn’t include the wcaxx driver so I had to fix that according to the bug report I found on launchpad. Then I still can’t get the damn service to run. No init script for it is ever installed. So after a few hours of messing with it I decided to try and build it from source. A few more hours of attempts go by and I finally found this post. Thanks for posting this as I would still be totally fuxored. Guess I’m going to have to go with some old version of ubuntu server to get this garbage working again.
