Thanks for the info.
The solution was very simple : link with g++ (instead of gcc).

Hi,
Mixing C++ with C code is not that easy, unfortunately.
(Especially in the sense you are interested in, that is include C++ in C code)
Have a look here:

Subject: Re: [Wireshark-dev] plugins and C++
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.

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.
