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

[<taraniteja.vishwanatha@xxxxxxxxx>]

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
