Wireshark · Wireshark-dev: Re: [Wireshark-dev] Compilation error in asn.1 file

["Anders Broman" <a.broman@xxxxxxxxx>]

Hi,
Ok I think I remember now you are dealing with ANSI TCAP stuff - right?
And you are hand writing the asn1 file?

I don't think asn2wrs can handle "ANSI OPERATIONS" in theory you should
IMPORT OPERATIONS like:

IMPORTS
	OPERATION
FROM TCAP-Remote-Operations-Information-Objects {iso(1)memberbody(2)
usa(840) t1-114(10013) 
	modules(0) informationObjects(1) version4(4) }

And that asn1 file should be compiled with your asn1 file or you could
Declare the OPERATION class in our .cnf file.

However if you just define the parameters in the asn1 file like: 

xxxRequest ::= SEQUENCE {

aaa (2) AAA,

bbb (3) BBB }

xxxResult ::= 

(see ANSI MAP)

Then in your template file you'll have to make the connection from operation
code to xxxRequest.
Switch(code){
 Case xxx:
	Dissect_xxxRequest();
	Break;
}
A bit more complicated to get it called from ANSI TCAP but that depends on
How the ANSI TCAP bit looks in your case...

Regards
Anders

Hi ,

Let me explain you in detail. I have a protocol defined in asn.1 format ,
whose operations and parameters look like the ones mentioned below: 

Operation Code=1

Class=1

ASN.1 Formal Description 

xxxRequest ::= OPERATION

PARAMETER SEQUENCE {

aaa (2) AAA,

bbb (3) BBB }

RESULT

reqresult (4) ReqResult 

Parameters : 

xxx ::= ENUMERATED {

xxxNotActive (0),

xxxActive (1) } 

I have copied these exactly to generate my .asn file . I am still having
hiccups in generating the .cnf file. But the code is not getting compiled
and it is giving error at each line of the .asn file. 

BR.
Tarani
