[Mono-list] Remoting

[Wilhelm Patrick]

Hi!

I've a Problem using the remoting system of mono in my project. First of
all, hier is my code I use for initialization the client or server mode:

      switch (appMode) 
      {
        default:
        case AppMode.Server:
          // Register a new channel with the runtime remoting services
          ChannelServices.RegisterChannel(new TcpChannel(13100));

          // Register a type as a well-known type
          RemotingConfiguration.RegisterWellKnownServiceType(
          typeof(RemoteCtrl),
          "remotectrl",
          WellKnownObjectMode.Singleton
          );
	    //...

          break;
        case AppMode.Client:
          RemotingConfiguration.RegisterWellKnownServiceType(
            typeof(RemoteCtrl),
            "remotectrl",
            WellKnownObjectMode.Singleton
          );

          RemoteCtrl remoteCtrl = 
          (RemoteCtrl)RemotingServices.Connect(
          typeof(RemoteCtrl),
          "tcp://localhost:13100/remotectrl"
          );
          remoteCtrl.GetPatternGeneratorCtrl(out patGenCtrl);
          //...

          break;
      }

under windows everything work's fine, but when I try to run it under linux I
get errors: (the error is on client side: running the server doesn't make
any problems. For testing I run server and client on the same machine. I
have no firewall on my system)

first I run my server:
LINUX-S-01: # mono programm.exe -server

then I try to start the client from another console:
LINUX-S-01: # mono programm.exe -client
Unhandled Exception: System.Runtime.Remoting.RemotingException: Cannot

Segmentation fault

Can you tell me, why my program runs under windows but not under linux?

ok, I tried to use the mono-debugger, but it seems, that the debugger dosn't
work with the tools I use in my project: I use wxWindows with wx.NET for the
GUI and the first object that is created in main() is a object from wx.NET.
When I want to debug my application and type "continue" in the console
debugger, the programm ends immediately with "System.MissingMethodException"
and "Process @4 terminated normally". When mono-debugger loads my program I
get many "undefined symbol" warnings (which cause the
MissinMethodeException) in "libwx-c.so" (this lib is used for interactivity
between mono wx.NET and wxWindows.) I don't get this warnings when I start
my program with "mono program.exe" or "mono --debug program.exe".

I use the following versions:
mono-0.25
mono-debugger-0.4
wxWindows-2.4.1 (with gtk2)
wx.NET20030714
gtk-sharp-0.10
libgc-mono-6.1

Distribution:
Suse 8.2

Hope anyone can help me with the remoting problem.

Thank you for your help!
