Why do I get a link error when I call proto_tree_add_format_wsp_text() in my dissector?

I am trying to make a call to proto_tree_add_format_wsp_text. This method is implemented in proto.c in the epan folder. I can include the header file for it and it will compile, but it will not link because my project does not know where the object code is. When I build Wireshark, I assume that files like proto.c are compiled into a library or dll. I think I should be able to link to that. But what is the file I need to link to and where is it?

That function isn't exported from the libwireshark library, so can't be used by plugins.

To fix this you can temporarily prefix the declaration in proto.h with WS_DLL_PUBLIC and rebuild.

To create a permanent change you should submit a change at the Wireshark Gerrit instance. See the wiki page on Submitting Patches for more info.

Is there public code that I can call that would replace the call to proto_tree_format_wsp_text? Something I can call that will do basically the same thing?

That depends, what do you actually want to achieve? An example of the input bytes and the output display would help.
