Thanks for your help, but the problem still exisits.
I tried to change the code like you told:
Part of my packet-toyasn1-template.c:
#include "packet-toyasn1-fn.c"
static void
dissect_toyasn1(tvbuff_t *tvb, packet_info *pinfo, proto_tree *tree)
{
proto_item *toyasn1_item = NULL;
proto_tree *toyasn1_tree = NULL;
/* make entry in the Protocol column on summary display */
col_set_str(pinfo->cinfo, COL_PROTOCOL, PNAME);
/* create the toyasn1 protocol tree */
if (tree) {
toyasn1_item = proto_tree_add_item(tree, proto_toyasn1, tvb, 0, -1,
FALSE);
toyasn1_tree = proto_item_add_subtree(toyasn1_item, ett_toyasn1);
dissect_MESSAGE_PDU(tvb, pinfo, toyasn1_tree);
}
}
part of my toyasn1.cnf:
# toyasn1.cnf
# TOYASN1 conformation file
# $Id$
#.MODULE_IMPORT
#.EXPORTS
#.PDU
MESSAGE
#.NO_EMIT
#.TYPE_RENAME
#.FIELD_RENAME
#.END
The error still exists:
Couldn't load module
/home/obermaierc/Schreibtisch/wireshark-1.12.0/plugins/toyasn1/.libs/toyasn1.so:
/home/obermaierc/Schreibtisch/wireshark-1.12.0/plugins/toyasn1/.libs/toyasn1.so:
undefined symbol: dissect_MESSAGE_PDU
I dont know where the error comes from.

Hi,
You need to replace this line with the name of the top level PPU in your ASN.1
file. For example if you look at the files in asn1/c1222, you will see that the
c1222.cnf file contains:
#.PDU
MESSAGE
where MESSAGE is the top PDU in the c1222.asn file.
Then you need to edit the .c file to put the corresponding function name that
will be generated by asn2wrs (for c1222 dissector it is dissect_MESSAGE_PDU).
Regards,
Pascal. ___________________________________________________________________________
