Wireshark-dev: Re: [Wireshark-dev] Problems when trying to compile a new ASN.1 dissector

Frank,

If you want your ASN.1 type(s) to appear in the Decode As dialog, then
you should call register_ber_syntax_dissector within your dissector
registration function.

For example, in asn1/cms/packet-cms-template.c:
  register_ber_syntax_dissector("ContentInfo", proto_cms,
dissect_ContentInfo_PDU);

If you don't have the corresponding "_PDU" function, add the type to
the #.PDU section (http://wiki.wireshark.org/%23.PDU) of the .cnf
file.
