Try to build both with gcc3.3 or gcc4.0 but no a mix of the two.
It does not seem related to which OS you use, but wich compiler...

Please report back if it is the problem.

Thanks

I have a server which has a method called:
- (void)openFile: (bycopy in NSString *)fileName atCharRange: (NSRange)charRange;


When I compile this server on Panther I get:
    Proto-Methods:
        openFile:atCharRange: (v20@0:4nO@8{_NSRange=II}12)

When I compile this server on Tiger I get:
    Proto-Methods:
        openFile:atCharRange: (v20@0:4On@8{_NSRange=II}12)

Note the difference: 4On versus 4nO.

Now, when a Tiger-compiled client calls a Panther-compiled server (both running on the same computer) I get a console message:
... _preInitWithCoder:signature:valid:wireSignature:target:selector:argCou nt:
incompatible method params:
got NSMethodSignature: types=v@:On@{_NSRange=II} nargs=4 sizeOfParams=160 returnValueLength=0;
want NSMethodSignature: types=v@:nO@{_NSRange=II} nargs=4 sizeOfParams=160 returnValueLength=0;


Similar with the other cat-combination (client compiled on Pather, server compiled on Tiger).

What can I do to make Distributed Objects between different cats possible?

Kind regards,

Gerriet.
