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

This is on fedora27 with kernel-4.16.12-200. This problem has been going on for months. I haven’t been able to update since 4.14. Has something changed in the way in which dahdi is installed?
