[asterisk-users] DAHDI compile failed in xusb_libusb.c

[David Cunningham]

Hello,

We have just upgraded a server to Ubuntu 18.04, running kernel
4.15.0-142-generic. Compiling DAHDI 3.0.0 fails with the error below, and
3.1.0 gives the same error. The gcc compiler is version 7.5.0. Would anyone
know what the solution is, or should we open a bug report? Thanks in
advance for any help!
