Hello;
I've been working on trying to get the hello-world example client
and server (thanks incredibly much for the simple example to work with!)
running on CMUCL and CLISP, but have not been having much luck :-<. I
finally got myself stuck where I can't move any further, so I thought I
would ask here. I apologize in advance if the problems are due to my
inexperience with lisp.
CMUCL
-----
I thought I would start with this since I have had the most luck here so far.
I have been successful at starting up a server without any errors, but when
I open up a new interpreter and try to run a client against the server, I
get the following error in the client:
* (hello-client :file "hw.ior")
Error in function CLORB::UNMARSHAL-GIOP-HEADER: Not a GIOP message

The server also crashes when this occurs, with the following backtrace:

clisp
-----
On clisp, I get an error immediately upon trying to start up the server,
and it gives the following trace.

Could anyone offer any advice about what exactly is going on in either
case, or suggest further paths that I could try? Thanks in advance for any
help!

I have made a new release of CLORB. It can be downloaded from <URL:https://sourceforge.net/projects/clorb/> There has been a lot of interface chagnes to make this release close to the IDL/Lisp mapping. I also included an Hello World example using mostly standard interfaces. -- Lennart Staflin <le...@ly...> |

Hi Lennart;
Thanks for getting back with me! I thought I would send this to
your official development list...

Okay, this is no problem at all. I was just curious--what mapping
standard are you following. I had been looking around a bit and found
what appears to be the standard mapping on the omg page
(http://www.omg.org/cgi-bin/doc?orbos/99-05-18). Is this what you are
following? I know that ILU also has a LISP mapping, and I'm not
exactly positive if they differ. I just wanted to make sure I was
reading the right information :-)

That sounds great. I've been looking at things more, and I am in no
rush, so waiting for the POA interface changes in the next release is
no problem at all.
I was just curious, would you interested in assistance with any of
the coding on CLORB? As I mentioned, I'm really new to LISP and not
very proficient, but I am very interested in coding more in it to help
me learn. It is completely up to you, of course, but if you had a
small part of CLORB for me to work on, I would be very interested
(and appreciative for letting me help).
Again, thanks for responding and for CLORB.
Brad
