error: use of undeclared identifier 'SO_BINDTODEVICE'

[vollkommenheit]

Trying to compile mtr post 2022-7-20, I get:

CC packet/construct_unix.o packet/construct_unix.c:297:9: warning: unused variable 'udp_socket' [-Wunused-variable] int udp_socket = net_state->platform.udp6_send_socket; ^ packet/construct_unix.c:403:24: error: use of undeclared identifier 'SO_BINDTODEVICE' SO_BINDTODEVICE, param->local_device, strlen(param->local_device))) { ^ packet/construct_unix.c:626:24: error: use of undeclared identifier 'SO_BINDTODEVICE' SO_BINDTODEVICE, param->local_device, strlen(param->local_device))) { ^ packet/construct_unix.c:801:36: error: use of undeclared identifier 'SO_BINDTODEVICE' SOL_SOCKET, SO_BINDTODEVICE, param->local_device, ^ 1 warning and 3 errors generated. make: *** [packet/construct_unix.o] Error 1

This is likely affecting BSD-like systems such as macOS/Darwin, per https://sourceforge.net/p/net-snmp/patches/1296/ https://github.com/FRRouting/frr/issues/5978

It should compile again, but the big question is if the -I option works for you.

Yep, it compiles fine now. And -l seems to be working fine too. Thanks!
