Hello Anders,

It seems it can't handle qualified imports like 'OtherModule.TypeDefinedInOtherModule'.

Probably not.

One other problem is that all types are global. If I have 2 different modules that each defines a type like 'GlobalID' asn2wrs gives an 'Duplicate type' error.

The #.MODULE directive might work see gsm_map.

Regards
Anders

Because the Nokalva compiler works I will presume these are missing features.� My solution for now is to make sure every typename is unique and to avoid qualified imports.

Regards,

John

Hi,

You have to try to determine what statmet(s) in your asn1 file(s) throws as2wrs off, it looks like its related to tagged types any unusual complicated statements in there? Perhaps the order of inclusion matters?

Hello,

While trying to build an asn.1 dissector the asn2wrs.py tool gives the following error:

/usr/bin/python ../../tools/asn2wrs.py \
������� -b� \
������� -p xyz \
������� -c ./xyz.cnf \
������� -s ./packet-xyz-template \

AttributeError: Node instance has no attribute 'AddTag'
make: *** [../../epan/dissectors/packet-xyz.c] Error 1

Is this a bug. Is there someone who can give me some clue.

Regards,

John
