Thanks, that seems to have fixed it.

 

I’ve also fixed the link error by adding a #include <stdio.h> to the dissector. So I’ve got everything built.

 

One other question.

 

I have some other dissectors that used to live in their own directories in plugins. The changes to CMakeLists.txt seem to enforce these to be in a sub directory of plugins. Is that right?

I think, if you specify the full path, they can be anywhere.   You'll also need to tell the installer where to find the build outputs.

Hi,

 

I am trying to update to Wireshark 2.6 building for Windows 64bit. I have a custom GIOP dissector which was previously built for Wireshark 2.2.5

The dissector is in the file packet-q_quentin.c and I have copied that file to the epan/dissectors directory.

 

First, adding it to the CMakeListsCustom.txt file in epan/dissectors causes a build error – packet-q_quentin.c does not exist, except it does.

 

I have run cmake with a clean build directory and it still fails. So there seems to be a problem with the custom cmake list stuff.

 

Try prefixing your dissector with the cmake source path, e.g.

 

    ${CMAKE_CURRENT_SOURCE_DIR}/packet-q_quentin.c

 

Recent changes to the build infrastructure haven't updated the files not normally used in our builds, i.e. CMakeListsCustom.txt.example

 

 

To try and move on, I added my dissector to the CMakeLists.txt file. This now builds the dissector, but I get a link error saying unresolved symbol sprintf (which is used in my dissector).

 

I’m using Visual Studio 2015

 

So what do I need to do to make the custom cmake list work and how do I fix the link error.

 

Thanks for any help

 

Regards
