Hi I was trying to create a dll for my own dissector, compilation went through, in dll creation I am facing the issue as below. kindly provide views for the issue. Thanks in advance.

You should not link with both libwireshark.lib and dissectors.lib. Remove the latter and keep only libwireshark.lib.

The function you are calling (gsm_a_rr_rxlev_vals_ext, ...) are not exported, so you cannot call them from your external dll. They should either be declared as WS_DLL_PUBLIC in Wireshark source code (not likely to happen) or you should redefine them locally. Looks like you copy pasted the lte-rrc dissector code in your DLL. This does not seem to make a lot of sense to me. Again you should not link against dissectors.lib.

(01 Dec '15, 12:50) Pascal Quantin

the compilation is fine as it went through, the issue is with linking, i.e it is not allowing to call any function from epan\dissectors.

Note that @Viswanathan might be attempting to build an older version, maybe 1.8?

Can you clarify the source version you're working with?

The toolchain is VS2010.

(01 Dec '15, 15:56) grahamb ♦

I am using, 1.8.11

(01 Dec '15, 16:02) Viswanathan ...

Juts a info :I could able to compile & run the wireshark source code base 1.8.11 without any issue

the issue was resolved by - adding all export parameter libwireshark.def file & re compile - modifying the Makefile.nmake for remove the library ..\dissectors.lib in LINK_PLUGIN_WITH macro

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.
