this seems to be it: the interface repository contains a
LocalInterfaceDef, and the file clorb-ifr-base.lisp doesn't have a
definition for this (I can't remember when local interfaces were added
to CORBA, but it was quite a while ago).

I take it that clorb-ifr-base and ifr-idl are generated from the files
in the idl/ directory, using the new IDL parser? I tried to use
CORBA:IDL to generate lisp definitions for IDL files from ORBacus, but
the IDL parser also doesn't recognize local interfaces; it chokes on
the "local" bit of a definition like

,----
|    local interface Policy
|    {
|        readonly attribute PolicyType policy_type;
|        Policy copy();
|        void destroy();
|    };
`----

I guess I'll have to figure out how the parser is generated from the
IDL grammar.   

Thanks,

I think you got everything loaded, the 19th method is the one that=20
should have been used, but the object is a generic proxy instead of a=20
proxy for the particular IR object. Unfortunately CLORB is a bit lax in=20=

error reporting when unmarshalling object references. You get a generic=20=

proxy if there is not proxy class for the object type or if the object=20=

reference lacks type info (and there is no type info from the interface=20=

returning the object.)

I had a look at print-object for CORBA:Proxy uses object-id when it=20
should be using proxy-id. The "IDL:omg.org/CORBA/Object:1.0" is not the=20=

ID that came with the reference.

I can see at least two explanations
1. the interface repository returns object references with missing (or=20=

incomplete) type info, or
2. the interface repository has objects of types not known to the CLORB=20=

implementation, perhaps it implements a repository from some later=20
corba version.

You could try to inspect the proxy object to see what the ID slot=20
contains or fix print-object to use proxy-id instead of object-id.

Earlier versions of download-ir might have used Dynamic Invocation=20
instead of static stubs as the current version does. That would=20
probably have worked with any version of the interface repository.=20
Ironic :)

You could also try loading make-proxies.lisp and see if it works then.

Hi,

I tried to use DOWNLOAD-IR to populate the local repository, and ran
into the following error:

  No matching method for the generic function #<standard-generic-function omg.org/features:def_kind (19) {489E8C39}>,
  when called with arguments (#<omg.org/corba:proxy "IDL:omg.org/CORBA/Object:1.0" @hobart.laas.fr:39513>).
     [Condition of type pcl::no-applicable-method-error]

Inspecting the OP:DEF_KIND generic function tells me that it has the
following methods:

Is a method missing somewhere?   This is with CMUCL, and CLORB from
CVS, and I'm building using my own ASDF defsystem.
