How can I make my custom packet dissector distributable?

I built a custom packet dissector and I wanted to export it to others such that they don't have to rebuild their wireshark from source. I looked up README.plugins and README.developers for it but couldn't figure out a way to do this.

Typically, the target people for this dissector are people working on Linux environments (I have also developed the dissector on Ubuntu), and most of them have installed wireshark through sudo apt, therefore I want my plugin to be distributed as a simple binary or something which they can copy to their installations or maybe install on top of their current wireshark installation.

edit: I wrote the dissector in C.

Have you ever looked in the About Wireshark dialog? There's a Folders tab which shows the folders the program uses. Of particular interest may be Personal Plugins. What happens if you drop your file in there?

Hi @Jaap your solution worked. Thanks a lot! Also, can you elaborate if there is a method to compile the packet dissector (given suitable required files) as a standalone instead of running "make -C plugins" from the wireshark source? I also want to try the option of sending the source code of my dissector which the user can simply make on his machine.

You can contribute your dissector to the main Wireshark codebase and have it distributed on all supported platforms by the Wireshark project for free.

As a bonus, the dissector will be maintained by the Wireshark developers and you'll get your name added to the "Authors" list.

See the wiki page on Submitting Patches for guidance on how to contribute.

If you write your dissector as an LUA script then users can invoke it on the command-line (Linux, Windows, etc) using the -X argument. I use this myself for a few internal LUA scripts. It would then look something like:

wireshark -X lua_script:"pathToYourLuaScript"

I wrote the dissector in C currently. Is there any way to distribute the C dissector?

Hello, I understand it may be a normal built-in dissector, not as a puglin dissector. As most of user of Wiresharl are using windows OS, has it been tested for a Windows OS version of Wiresharlk? A DLL created already ? I am interesting in knowing about it. thanks.
