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

Hi,
OPERATION is not a predefined asn1 type, in GSM MAP operation is from:

:
IMPORTS
        OPERATION
FROM Remote-Operations-Information-Objects {
joint-iso-itu-t remote-operations(4)
  informationObjects(5) version1(0)}
:

And is used as:
sendRoutingInfo  OPERATION ::= {                                --Timer m
-- The timer is set to the upper limit of the range if the GMSC supports
pre-paging.
        ARGUMENT
                SendRoutingInfoArg
        RESULT
                SendRoutingInfoRes
        ERRORS {
                systemFailure |
:
I'm not sure what you are trying to achieve...
Regards
Anders

Hi ,

There has to be a PDU added before DEFINITIONS in the .asn file. I don't
have it but used it from existing asn files, though it is different for each
file.

After that I am getting the following error:

__main__.ParseError: LexToken(ASSIGNMENT,'::=',1,468)

I think it is giving a problem at the following assingnment :

XXX ::= OPERATION

Here , I want to know whether the keyword OPERATION is in the standard asn.1
notation , or some changes are required here?

Hi,

Is a problem in the .cnf file

Is a problem in the .asn file Line 199?

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

Hi ,

I have written .asn and  .cnf files for my dissector. I have created a
nominal template.c and template .h files as I suppose the asn2wrs compiler
would generate the functions and declarations. I also suppose I should add
the variable declarations and function definitions after the compilation.

I am getting the following error while compiling :

python ../../tools/asn2wrs.py -b -e -p tsrp -c tsrp.cnf -s
packet-tsrp-template tsrp.asn
ASN.1 to Wireshark dissector compiler
tsrp.cnf:65: UserWarning: Duplicated FN_PARS for Command. Previous one is at
tsrp.cnf:57
  #.FN_BODY  Command Result VAL_PTR = &parameter_tvb
Traceback (most recent call last):
  File "../../tools/asn2wrs.py", line 4875, in ?
    eth_main()
  File "../../tools/asn2wrs.py", line 4831, in eth_main
    ast.extend(yacc.parse(f.read(), lexer=lexer, debug=pd))
  File "/home/eth/plugin_dev/wireshark_tsrp/wireshark/tools/yacc.py", line
334, in parse
    tok = self.errorfunc(errtoken)
  File "../../tools/asn2wrs.py", line 4705, in p_error
    raise ParseError(str(t))
__main__.ParseError: LexToken(DEFINITIONS,'DEFINITIONS',1,199)
make: *** [packet-tsrp.c] Error 1

I am not sure the error is pertaining to .asn, .cnf or the template
files.Can somebody please help.

BR,
Tarani
