Hi
I meet a problem, i define a global variable e.g. g_sctp_packet_analyzing_debug in packet-sctp.c, then we want to access it in tshark.c. even make a statement in tshark.c, i still meet link error undefined reference to `g_sctp_packet_analyzing_debug. i know it should be linked with packet-sctp.o, but seems that wireshark compile system don't generate object file packet-sctp.o, i am not familiar with wireshark compile system.
Any expert can help me this out? thanks.
Any symbols put in libwireshark (e.g., from packet-sctp.c) need to be 
exported by being listed in epan/libwireshark.def .  (That file used to 
be only for Win32, but now *NIX builds also use it.)
