asn.1 compilation

Hello. I'm having troubles compiling asn.1 files from http://www.3gpp.org/ftp/Specs/archive/24_series/24.080/ASN.1/ I'm getting syntax error (syntax error at line 264 in module SS-Operations.asn: got 'SEQUENCE' expected ':') while running erlc SS-Operations.asn using Erlang version 15.b.1 As far as I recall Harald has done this for MAP asn.1 Are there any hints on what might be wrong? Tried online compiler but it gives different errors in different places. Should I use different version? Compile smth else before attempting to compile this file? Fix syntax using some clever trick? Do some rtfm? Any advices would be greatly appreciated. -- best regards, Max, http://fairwaves.ru
