Couldnt load module: undefinded symbol: dissector_add

0

Hi, i try to make a plugin based ASN1 dissector. I used the toyasn1 sample and only added my .asn files to the makefile of the Plugin. Now if i start wireshark i always get the error: Couldn't load module /wireshark-1.10-9/plugins/toyasn1/.libs/toyasn1.so: /wireshark-1.10.9/plugins/toyasn1/.libs/toysn1.so: undefined symbol: dissector_add

The same error occours with dissector_delete.

Does someone know how to solve it?

The api changed to dissector_add_uint() I believe.

Ah ok, thanks, i think you are right. But now, i get the same Error with undefined Symbol: dissector_add_unit

I don't know what that error means.

_uint, not _unit

Aww.. thats right. Sometimes reading is difficult.

Now i geht the Error undefined symbol: dissect_TOYASN1_MESSAGE_PDU

I think this problem lies in my toyasn1.cnf right?

Because i changed the .asn input files, the dissect_TOYASN1_MESSAGE_PDU function ist not created. My .asn files are CAM.asn and ITS-Containor.asn. In an other dissector, the dissect_name_PDU is created in the packet-name-fn.c file, but in my file is no such function

thank you very much for your help!
