Hello,

I have a C++ dissector which works on Windows.


I try to generate it on Ubuntu 9.10.
For testing purpose on Ubuntu 9.10, I removed everything except intantiating a C++ object : 
ofstream ofs ("wireshark_generic_dissector_traces.txt");
The makefile I use is a copy/paste of another dissector (not a C++ dissector), with only 3 modifications : 
- change the source files !
- add .cpp into ".SUFFIXES: .c .cpp .lo .o .obj"
- add .cpp rule ".cpp.lo: ..." which is copy/paste of ".c.lo:"

The generation works, BUT ...
When I launch wireshark, my dissector is NOT loaded with the following error : 
Couldn't load module /home/olivier/.wireshark/plugins/generic.so:
/home/olivier/.wireshark/plugins/generic.so:
undefined symbol: _ZTTSt14basic_ofstreamIcSt11char_traitsIcEE

Even if I remove the C++ object (C++ include still here) :
undefined symbol: _ZNSt8ios_base4InitD1Ev


I do not know which options are necessary to fix the problem.
Any idea welcome.

Lidwa, Eric (GSFC-582.0)[SGT INC] a écrit :


Good afternoon,
I have written several dissectors so far, one for AOS (Space Data Link Protocol) and two for different versions of DEM (Data Exchange Message). The dissectors were implemented as plugins.
I am now implementing dissectors for the payload part of one of the protocols. Without going into details, if I could call or even compile some existing C++ code into my dissector it would make my life a lot easier.
So here is a question, has anybody been able to write a plugin dissector in C++? I thought I ask before diving into hacking the makefiles. One thing to mention is that I do not care for multi platform support as long as “my” Wireshark runs on the particular real time linux I am using. 

Regards,

Eric Lidwa

#
# Build plugin.c, which contains the plugin version[] string, a
# function plugin_register() that calls the register routines for all
# protocols, and a function plugin_reg_handoff() that calls the handoff
# registration routines for all protocols.
#
# We do this by scanning sources.  If that turns out to be too slow,
# maybe we could just require every .o file to have an register routine
# of a given name (packet-aarp.o -> proto_register_aarp, etc.).
#
# Formatting conventions:  The name of the proto_register_* routines an
# proto_reg_handoff_* routines must start in column zero, or must be
# preceded only by "void " starting in column zero, and must not be
# inside #if.
#
# DISSECTOR_SRC is assumed to have all the files that need to be scanned.
#
# For some unknown reason, having a big "for" loop in the Makefile
# to scan all the files doesn't work with some "make"s; they seem to
# pass only the first few names in the list to the shell, for some
# reason.
#
# Therefore, we have a script to generate the plugin.c file.
# The shell script runs slowly, as multiple greps and seds are run
# for each input file; this is especially slow on Windows.  Therefore,
# if Python is present (as indicated by PYTHON being defined), we run
# a faster Python script to do that work instead.
#
# The first argument is the directory in which the source files live.
# The second argument is "plugin", to indicate that we should build
# a plugin.c file for a plugin.
# All subsequent arguments are the files to scan.
