How to retrieve Wireshark version during compilation

Question

Hi all,

Anybody knows, how to get Wireshark version during compilation ? I am writing a dissector plugin, and I would like to be able to build this plugin under different version of Wireshark. The interface functions prototypes can differ in different version of Wireshark, so I would like to check it during build, something like this:

#if CURRENT_WIRESHARK_VERSION >= VERSION(10,1,0)
...
#else
...
#endif

Is it possible to get a version somehow?

Answer 1

You should use the following preprocessor variables: VERSION_MAJOR, VERSION_MINOR, VERSION_MICRO

For example in my own plugins I use this kind of code:

#if (VERSION_MAJOR > 2) || ((VERSION_MAJOR == 2) && (VERSION_MINOR >= 1))
    sqnmbim_handle = create_dissector_handle(dissect_foo, proto_foo);
#else
    sqnmbim_handle = new_create_dissector_handle(dissect_foo, proto_foo);
#endif

Unfortunately for you there's no pre-processor definition of the build version. I guess one could be generated by the build systems, CMake and autotools. I suggest you file an enhancement request for this on the Wireshark Bugzilla.

Edit: Ignore, the answer from @Pascal Quantin is the correct answer.
