Wireshark build error

edit

I'm getting the following error while trying to build a plugin for wireshark 3.2.1 on my PC (windows 10)

C:\Users\ravishas\Desktop\wsnew\plugins\epan\expand\packet-expand.c(778,43): warning C4113: 'void (__cdecl *)(tvbuff_t *,packet_info *,proto_tree *)' differs in parameter lists from 'dissector_t' [C:\Development\build_try\plugins\epan\expand\expand.vcxproj]

C:\Users\ravishas\Desktop\wsnew\plugins\epan\expand\packet-expand.c(778,43): warning C4133: 'function': incompatible types - from 'void (__cdecl *)(tvbuff_t *,packet_info *,proto_tree *)' to 'dissector_t' [C:\Development\build_try\plugins\epan\expand\expand.vcxproj]

I have looked into the function and there is an additional " void * " parameter in the dissector_t function. Should that parameter be retained or is there any other workaround?

Thanks in advance
