1. Are you building on Windows or *nix ? What compiler are you using ?

   You speak of DLL's (which are Windows) yet you also speak of
   modifying makefile.am which is *nix.
   The two don't mix. Eg: You can't use makefile.am & etc when
   building on Windows.

2. The patch file attached to bug #3422 when applied to the Wireshark
   source does *not* add the dissector as a plugin
   but changes the source to build the dissector
   as an integral part of Wireshark; Therefore I don't
   understand what you are actually doing when you speak of generating
   a genisys.dll.

   Did you change things around to try to build the dissector as a DLL ?

   I suggest that the your first step is to build Wireshark using the
   genisys dissector (and changes to certain other source files) exactly
   as supplied in the patch.

   Trying to change things to build the dissector as a plugin is not the
   way to start if you're new to Wireshark development.

3. It appears that you are unfamiliar with the 'patch' program
   and how it works. Again I suggest you review the Developer's Guide as
   mentioned above. See sections 3.9, 3.10 and 4.14 for information on
   patch.
