Hi Roland,

The dissector is called Syncro and it allows a remote process to access the WS 
plugin_if extensions through a TCP connection.  We wanted to be able to achieve 
this without building a custom version of WS and so built it as a dissector.  
We don’t use any of the GUI stuff from Qt, just the TCP server functionality, 
multi-threading functions and Signals & Slots to communicate between threads.

Best regards…Paul

Paul, could you give an example, why you chose Qt libraries over Gtk? Was it 
not possible, or is it a personal choice?

I do have plugins for WS, which use Qt, but not for dissectors, so I am just 
curious, what was missing.

regards
Roland

Hi,

I have written a plugin dissector that uses some Qt5 functions.  To build with 
Visual Studio 2013 I have to manually add some Qt5 libs via Project -> 
Properties -> Linker -> Input -> Additional Dependencies.  This works OK but 
whenever I run:

cmake -D ENABLE_CHM_GUIDES=on -G "Visual Studio 12 Win64" ..\

to prepare the environment the Qt5 additional Dependencies are deleted.  How 
can I add my additional libs to the Cmake process in a way that won’t interfere 
with the standard build process?  Or should I be doing this some completely 
different way?

Thanks and regards…Paul



Although I'm suspicious of why a dissector should need anything from Qt, have a 
look at the CMake wiki page for "Finding a library" at 
https://cmake.org/Wiki/CMake:How_To_Find_Libraries

Basically add the appropriate find_package(), include_directories() and 
target_link_libraries() calls to the CMakeLists.txt of your plugin for the QT 
library you want.

Note that this behaviour is by design, CMake generates the Visual Studio 
solutions and projects from the info in the CMakeLists.txt files, there is no 
way to make changes in the VS IDE and push them back into the CMakeLists.txt 
files (except if you open the file in the VS editor).

You might also have to add steps to the CMakeLists.txt to copy the required Qt 
DLL to the staging directory and the update the packaging scripts to put it 
into an installer (packaging\nsis\custom_plugins.txt).
