Hello
I would like to use Distributed Objects to communicate through the
network between Objective C GNU Step application (let's say running
on Linux) and it's Mac OS X counterpart). Does anybody have any
experience using DO in such configuration? Is GNUStep's DO
implementation compatible with Cocoa's one?
No, the two implementations are not binary compatible, and making them
compatible would be quite a big job (though it's certainly not
impossible ... as we have a binary compatible implementation of keyed
coding for NIBs already, and Nikolaus Schaler has written a binary
compatible version of NSSocketPort for mySTEP which GNUstep could
use ... so a project to implement binary compatible DO would need to
re-implement NSConnection and NSPortCoder to use those).
Currently, for IPC between GNUstep and Cocoa I'd recommend using
XMLRPC. The GNUstep webservices library provides (as a tiny part of
its functionality) an XMLRPC coder and invocation methods, and this
library can be built/used either with gnustep-make (for gnustep) or
with xcode (for cocoa).
