CORBA::MICO-0.6.3 ================= Perl Interface to MICO (Mico Is COrba) version 0.6.3 Status ====== Basic client and server functionality is currently working. Quite a few things are left to be done. A few of them are: - wchar and wstring types 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 v2.3.5 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 has been tested with perl5.6.0, and perl5.005_03) For the demo programs you'll may want the Data::Dumper module from CPAN: http://www.perl.com/CPAN/modules/by-module/Data Once you have MICO installed, to build this package, 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: ---------- Using /usr/home/owen/tmp/CORBA-MICO-0.6.3/blib Balance is +500.00 Favorite color is taupe Lottery numbers are 21 63 83 96 Nickname is Dopey /****\ ; ; [ O O ] l \ l ; -- ; ;;;; Favorite color is now chartreuse As an any: favorite color is now chartreuse As an any: nickname is now Grumpy 2 * 1,000,000,000,0000 pennies = 20000000000000 pennies Withdrawing $100,000 Oops. I don't have that much money (I need +99500.00 more) created counter! 1 2 3 4 5 6 7 8 9 10 destroyed counter! created counter! Successful completion ---------- 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 0.5 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 ------------------------ [ This demo is not currently working with the new POA-ized code ] 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. -------------- Balance is +250.00 Favorite color is taupe Lottery numbers are 21 63 83 96 Nickname is Dopey Closing server... Trying to reactivate... Favorite color is now chartreuse As an any: favorite color is now chartreuse As an any: nickname is now Grumpy Withdrawing $100,000 Oops. I don't have that much money (I need +99750.00 more) 1 2 3 4 5 6 7 8 9 10 Successful completion --------------- Trying the shlib example ------------------------ cd shlib ./hello Note on the start-servers.sh ============================ In actual operation, you probably wouldn't want to keep killing and restarting the servers (ird and micod) as this script does. But doing so when testing things out makes it a lot easier to make sure that the current test isn't being affected by previous test failures. ================= URLs : http://corba-mico.sourceforge.net Authors: Owen Taylor (original author) and Nikolai Logvinov (current maintainer) Contact: Nikolai Logvinov ================= License ------- This work is Copyright Owen Taylor, 1998-1999, and licensed under the terms of the GNU Library General Public License (LGPL) See the included file LICENSE-LGPL for details.
