Title: Message
Hi Casper & Salim:
 
I am not sure if this is a limitation of the Erlang ASN.1 compiler, but I've had experience with other commercial compilers,
and they do support the MACRO's OPERATION and ERROR, though MACRO's are a depracated feature of ASN.1. Also,
I've used GSM MAP (a small subset of it) as my input.
 
thanks & regards,
banibrata.

Subject: Re: [ASN1] ASN ERROR and OPERATION

hello Casper,
 
Errors and operations are usually removed to be able to compile with an ASN1 compiler.
The operations are usually one argument message followed by a result or error. This has to be handled by the application part and not the compiled library. You should try compile just the messages and at the application level make sure you send and receive the correct ones depending on the scenarios.
 
That is the way i did it anyway with the various ASN1 compilers i used. If you need the ready to use GSMMAP ASN1 file, let me know.
 
-Cheers-

Dear All,

I am trying to compile ASN specification of GSM MAP I extracted from 3GPP TS
09.02 V6.14.0 (2003-09) using Erlang/OTP Asn1 compiler.

Bit I find some problems when try to compile. With the help of book of
Olivier Duboisson at: http://asn1.elibel.tm.fr/en/book/index.htm, I managed
to finally notice that the ASN error occurs when it tries to handle ERROR
and OPERATION types.

I tried with ITU Q.733, X.880, X.882 asn files I downloaded and including
Remote-Operations-Information-Objects.asn and other files , but nothing
helped to solve the problem.

Where is it wrong? Is it the ASN syntax in GSM MAP specification or the
Erlang ASN compiler doesn't know how to handle those 2 types? Or is that
syntax an out dated or very new one?

Thanks!
Eranga
