Package: dahdi-dkms
Version: 1:3.1.0+git20230717~dfsg-7
Severity: important
Hi,
dahdi-dkms fails to build a module for Linux 6.11 in experimental.
I haven't looked in detail, but this is probably caused by the switch
from gcc-13 to gcc-14 (and not a kernel interface change).
gcc-14 enabled -Werror=incompatible-pointer-types etc. by default.
