Via much help and direction from the linux networking mailing list and the modem manager mailing list I find myself here. The latest version of raspbian for the RPi 2 had such an old version of ModemManager packaged up it's not supported so I started on a bit of a Linux From Scratch trip to install later versions of both the ModemManager and NetworkManager. ModemManager built but NetworkManager is giving me a compile time error which I think is strange. dhcp-network.c:79:17: error 'BPF_XOR' undeclared I'm happy enough that it's an error but I'm confused that it didn't first complain that it failed to find a header file? I'm running the latest kernel (3.18.13) which I cross compiled on another computer so all the linux headers on the RPi 2 are from the older kernel. So I have to get my linux into a place where NetworkManager build can pick them up, but like I say above I'm unsure why the header file wasn't first falgged as an error. Searching through the linux source tree I find that definition in: include/uapi/linux/bpf_common.h Because of the lack of header warning I'm wondering if that is the header at all and wheather there's some other issue with my build? Perhaps I should not be using the later kernel at all?
ah sorry. You are using the latest headers... :) are you sure about that? Use the headers that match your kernel. Thomas
