Wireshark-dev: Re: [Wireshark-dev] make a extension for packet-sctp.c, meet a problem.
Hi
Thanks, yes,add all exported symbols in epan/libwireshark.def can fix my problem.
Another problem, i want to add a file named as sctp_packet_lost_stat_dlg.c in gtk directory, and add menuitem SctpPacketLostStat in Statistics.
in order to make this menuitem available, i make some change in menus.c, also modified gtk/Makefile.common to make sctp_packet_lost_stat_dlg.c be compiled in to
wireshark. like the following
WIRESHARK_GTK_SRC = \
about_dlg.c \
........
summary_dlg.c \
sctp_packet_lost_stat_dlg.c \
..........
but i still get compile error

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.
