Hi



         followup question, it does the creation of dissector dll for RRC
successfully, when it loads on wireshark , it throws a error: "The
procedure entry point dissect_lpp_Ellipsoid_Point_PDU could not be located
in the dynamic link libwireshark.dll "

any suggestions.


Hi,

as explained in your question on ask.wireshark.org (
https://ask.wireshark.org/questions/48152/lte-rrc-dissector-linker-issue)
this symbol is not exported by Wireshark. So your plugin will not work with
a standard Wireshark version.
You have not explained yet why you try to duplicate the already existing
LTE RRC dissector. If your changes are intrusive enough to require
accessing those functions, you should probably modify the source of LTE RRC
dissector directly and compile your own version of Wirehsark, rather than
making a plugin. Or you will need to copy / paste plenty of code in your
own plugin, but that could collide with the embedded dissector.
But without knowing your own constraints, we cannot really confirm whether
the choice to make a plugin was the best one or not.

Best regards,
Pascal.
