1 | initial version |
In all likelihood various APIs have changed and you will need to modify your dissector to work with the new version. Without knowing the exact errors you're seeing, you'll just have to work through them one at a time.
Try starting with a re-read of the documentation such as the Wireshark Developer's Guide as well as the various README files, i.e., README.developer, README.dissector, README.plugins, etc. You have full access to all the source code, so you should be able to use other dissectors as guides in porting your dissector to the new version too.
