CORBA::MICO-0.2
===============
Perl Interface to MICO (Mico Is COrba) version 0.2
Status
======
Basic client and server functionality is currently working.
Quite a few things are left to be done. A few of them are:
- Constants
- Shared library activation mode
None of these are particularly hard to do given what works
now - they just haven't been done yet.
Documentation
=============
General information about a mapping of CORBA onto Perl is in
the available in the file 'MICO/mapping.pod' while specifics
about MICO are in 'MICO.pm'. Information about the internals
of the module is in 'MICO/internals.pod' These POD documents
can be viewed on the screen using the 'perldoc' program:
perldoc MICO/mapping.pod
or converted to a variety of formats, for example:
pod2html MICO/mapping.pod > MICO/mapping.html
They will also be installed as manual pages.
The file MICO/internals.ps is a diagram that may be useful
for figuring out MICO/internals.pod.
Installation
============
To compile and run this package, you'll need to have MICO v2.0.6
or better installed. Information about MICO is availaible from:
http://diamant-atm.vsb.cs.uni-frankfurt.de/~mico/
You'll also need Graham Barr's Error module - available
from CPAN in the directory:
http://www.perl.com/CPAN/authors/id/GBARR/
And a reasonable recent version of Perl. (This is only been
tested with perl-5.004_58-64, but it should work with the
stable perl-5.004_04 as well, and probably even earlier versions).
For the demo programs you'll also need the Data::Dumper
module from CPAN:
http://www.perl.com/CPAN/modules/by-module/Data
Once you have MICO installed, to build this package, first
edit Makefile.PL, if necessary. The only thing that will
probably need to be changed is the line:
'LIBS' => ['-lmico2.0.6 -lstdc++'],
Change -lmico2.0.6 to reflect whatever version you have
installed. (This problem wouldn't occur if MICO set
up the correct symbolic links when installed)
Then simply type:
perl Makefile.PL
make
The package then can be installed by executing the command:
make install
Trying it Out
=============
To start the interface repository, load in the Account.idl
interface file, and create an appropriate .micorc, run
the script
./start-servers.sh
Run the Perl server program in the background:
perl -Mblib server &
And then run the client program:
perl -Mblib client
You should see output that looks something like:

Trying the GTK Demo
===================
To use this demo you must have GTK installed on your system
and the Kenneth Albanowski's Gtk module for perl (version 0.1.16 or
later). Both are available from
ftp://ftp.gimp.org/pub/gtk
Then, start up the servers with
./start-servers.sh
and run two copies of the 'tictactoe' program
perl -Mblib tictactoe &
perl -Mblib tictactoe &
Trying the micod example
------------------------
Warning: I had major problems trying to get this to work using
egcs-1.0.2 and mico-2.0.5. The micod daemon core-dumped
until I recompiled it as static. This seems to have gone away
with mico-2.0.6.
./start-servers.sh
perl -Mblib client-activate
The client will automatically start up the server (as registered
in 'start-servers.sh'). Halfway through the server process,
it writes its state to disk and exits. Then is automatically
restarted, and restored from disk by micod.
