You can find all instructions in README.plugins:

As for C++ code, the Wireshark is a C only project, you should read up on the
portability guidelines in README.developer:

So for using C++ you're somewhat on your own.

1.1.1 Portability.

Wireshark runs on many platforms, and can be compiled with a number of
different compilers; here are some rules for writing code that will work
on multiple platforms.

Don't use C++-style comments (comments beginning with "//" and running
to the end of the line); Wireshark's dissectors are written in C, and
thus run through C rather than C++ compilers.

Hi Ankit,
Thank you very much Ankit, I 'm trying to follow the 1st method. the
question i have is the code i have written is in C++, i guess the
wireshark is compiled with CC ,Does CC can compile the C++ code, i have
used C style of C++ without much OOPS concepts.

Thanks and Regards

For doing this firstly, you have to download the latest source of
You have two options that can be done for your code to be included in

i) Compile your code into the wireshark main dissectors...
--> for this just take your .c file and paste it in the
(root)/epan/dissectors directory, where all the other dissectors are
placed. Now, to make changes in the makefile to reflect in the
compilation, just add your .c filename in the Makefile.common file in
-->Makefile.common is the common part of the makefile in both Windows
Linux platform.
-->Just go and edit the label DISSECTOR_SRC of this file and add your
filename in this list.
-->If your code also contains a header file then add it in the
--> compile the wireshark source from the root directory of

ii) compile a plugin for wireshrk(.so file)
-->Assumption here is that your plugin already contains the required
makefiles(ie, makefile.am [2] and makefile.common)
-->Now these are the places where you have to edit the wireshark code
telling it to compile and execute your plugin...
a)root_direc/configure.in [3] - somewhere near line 1861 - add path
makefile of your plugin
b)root_direc/Makefile.am - line 277 - add the path to .la file of
c)root_direc/epan/Makefile.am - line 221 - add path to the .c file of
the dissector.
d)root_direc/plugin/Makefile.am - line 35 - add your module in the
list of plugins.
-->compile the wireshark as usual.
-->new files will be generated in your plugin folder.
-->Now just copy the mih.la [4] file and mih.so (inside .libs folder
plugins folder) from the plugin and paste it into the
/usr/local/lib/wireshark/plugins/ folder.
Now run the wireshark tool and your plugin should start working.

Let me know if there are further problems
