Re: error LNK2001: unresolved external symbol (linking with dissctors.lib)

If you are building a plugin export of true_false and value strings does not work. Define them locally
foo_tfs_set_notset.

Not sure what you mean by this rohc was explicitly moved into it's own dissector as rohc is it's own protocol and may
be used directly on Ethernet. Moving it back into PDCP seems like the wrong thing to do.
If you want to work with the community you might consider offering your changes as patches.

Anders

Yes...

The usual cause is the symbols not being exported as they aren't in libwireshark.def
