I will check out if GLIB2 is really necessary for windows and make it conditionally if so.

And yes I'm intended to make the tool working in Linux and FreeBSD too. Because it is only using a socket connection to the device, it should be easy to get it working for any platform.

The hardest platform to get it working is windows so I started with that one.

That is in fact the correct solution. I am not really sure why GLIB2_LIBRARIES is needed in this general way, but you will always have to look at your cmake files from a cross-plattform POV to ensure, that your utility is being built on all platforms. It is strongly recommended, that you build your extcap on at least two different platforms (Linux and Windows for example) if you want your extcap to be included in the general wireshark build. Except if it provides a functionality only available on a specific platform, but then the inclusion in the build itself can be conditional (aka only build it, if you are on the correct platform).

cheers

I fixed it: the function is in 'ws2_32' and I added it conditionally as
follow in my "snippet" (anagate is my target):

if(BUILD_anagate)

     set(anagate_LIBS
         wsutil
         writecap
         ${GLIB2_LIBRARIES}
         ${CMAKE_DL_LIBS}
     )
     if(WIN32)
         set(anagate_LIBS ${anagate_LIBS} ws2_32)
     endif(WIN32)

     set(anagate_FILES
         anagate-core.c
         anagate-intf.c
         extcap-base.c

     )
     set_executable_resources(anagate "anagate")
     add_executable(anagate ${anagate_FILES})
     set_extcap_executable_properties(anagate)
     target_link_libraries(anagate ${anagate_LIBS})
     install(TARGETS anagate RUNTIME DESTINATION ${EXTCAP_INSTALL_LIBDIR})
     add_dependencies(extcaps anagate)

endif()

Thanks for pointing out that is was "ws2_32" where this function is
located (your first reply was right).
