Adding a dissector to wireshark does not show in Edit->Preferences protocols - why?

Hello, I am trying to add a dissector to Wireshark in Linux. I work with wireshark 1.2.3. I do not have previous experience and my trial is based upon the wiki and from reading wireshark source code What I tried is a very basic code, (somthing which can be though of as HelloWorldDissector) , when my goal is to add a dissector which in fact does almost nothing, so that first I will be only able to see it in preferences of wireshark, in the list of protocols, as "SEQ". Here is the short code I created (in a file called packet-seq.c): #ifdef HAVE_CONFIG_H #include "config.h" #endif #include <stdio.h> #include <stdlib.h> #include <string.h> #include <gmodule.h> #include <epan/prefs.h> #include <epan/packet.h> void proto_reg_handoff_seq(void) { } void dissect_seq(tvbuff_t *tvb, packet_info *pinfo, proto_tree *tree) { col_set_str(pinfo->cinfo, COL_PROTOCOL, "FOO"); col_clear(pinfo->cinfo, COL_INFO); } static int proto_seq = -1; static dissector_handle_t seq_handle; void proto_register_seq(void) { module_t *module; if (proto_seq == -1) { proto_seq = proto_register_protocol("SEQ protocol", "SEQ", "seq"); }; module = prefs_register_protocol(proto_seq, proto_reg_handoff_seq); } Now, I added this line in register.c: {extern void proto_register_seq (void); if(cb) (*cb)(RA_REGISTER, "proto_register_seq", client_data); proto_register_seq ();} And I added entries in the Makefile according to other dissectors. I build it, and a binary called libdissectors_la-packet-seq.o is created under: /work/src/wireshark-1.2.3/epan/dissectors/.libs However, when I start wireshark I do not see it in the Edit->preferences , in the protocol list. Any idea what am I missing here?
