Wireshark · Wireshark-dev: Re: [Wireshark-dev] Error loading plugin

[Roland Knall <rknall@xxxxxxxxx>]

Very simple reason for that: We build Wireshark for version Qt 5.3, with VS 2015. Make sure, you are using the same versions of our libraries, if you are using them in your plugin.

cheers, Roland

Hi Paul and Pascal,

Interesting theory Paul! I am going to try both and let you know what happens.

Hi Juanjo Martin,

 

This feedback might be a bit naïve (particularly as Pascal knows this stuff better than me) but I think it might be down to naming.

 

Assuming:

 

• Your dissector function is called dissect_shapetype(…)
• Your registration handoff function is called proto_reg_handoff_shapetype(…)
• Your dissector registration function is called proto_register_shapetype(…)
• And you register the protocol with an abbreviation shapetype

 

I think you should generate a plugin called shapetype.dll.

 

Best regards…Paul

Hi Juanjo,

Hi all,

 

I am developing a plugin. It works for me but when I try to give it to other developers, some of them get the following error:

 

I am using VS2012 in Windows 64 bits and I have asked one of the developers to try installing the redistributable for that version and still failing.

I have tried searching in the code but I can't find anything that leads me to a solution. Any thoughts?

 

Just some blind guesses based on my past experience:

- have you built the plugin against the source code of Wireshark 2.4.X? Wireshark does not ensure (understand systematically breaks in practice) the API between major releases so a plugin built for Wireshark 2.5.1 cannot work with Wireshark 2.4.5

- are they running a Wireshark version matching the architecture (x86 vs x64) used to build the plugin (but if I remember correctly the error differs in that case)?

- Wireshark 2.4.x official installers use MSVC2015, not 2012. Could you build the plugin using MSVC2015 Community Edition and check whether it works fine?

Regards,
Pascal.
