Getting started

[Iain]

I've downloaded and installed Ice-3.4.2 and created the demo programs in Python 2.6. These work perfectly. I then built the C++ sample from the manual using Visual Studio 2010 running under Windows 7 (64-bit) and tried to run that. I've got two problems:

1. The line below gives me an access violation. Moving the value to a temporary fixes the issue (I'm using the debug heap):

   adapter->add(object, ic->stringToIdentity("SimplePrinter"));

2. After fixing the above I can then start the server and client, but I get an OperationNotExistException in the generated Printer.cpp file:

   ::Ice::DispatchStatus
   Demo::Printer::__dispatch(::IceInternal::Incoming& in, const ::Ice::Current& current)
   {
       ::std::pair< ::std::string*, ::std::string*> r = ::std::equal_range(__Demo__Printer_all, __Demo__Printer_all + 5, current.operation);
       if(r.first == r.second)
       {
           throw ::Ice::OperationNotExistException(__FILE__, __LINE__, current.id, current.facet, current.operation);
       }

   The current operation appears to be an empty string, and it is failing on the client's checked cast. The same thing happens if I try connecting the Python client to the C++ server.

I'm building a 32-bit application, linking against the 32-lib libraries in the "vc100" subfolder (the main folder gives the same result).

Has anyone had a similar problem, or know what the solution is?

Iain,

Welcome to the forum.

Are you sure you're linking with the debug version of the Ice libraries? See this FAQ for more information.

Cheers,
Mark

Thanks Mark - that was the problem. I've now got what looks like a VC runtime mismatch, but should be able to sort that out this evening.

Thanks again for the quick reply.

I've got the demo working. For the benefit of anyone else with the same issue:

• match the version of the Visual Studio runtime brought in via ZeroC libs with your VS version (use dependency walker if need be to check). VS 2010 libs are in "vc100" subfolder of lib.
• this extends to DLLs - check which you are loading at runtime from the path - make sure that you've got the "ice-3.4.2/bin/vc100" folder rather than "ice-3.4.2/bin" if you're using VS 2010.

This is definitely a VS problem rather than a ZeroC issue, but it might be helpful to put a note about VS runtime versions in the C++ demo section of the manual to help any other similarly clueless people?

Hi Iain,

We do describe how to configure your environment in the Using the Windows Binary Distribution of the release notes.

Glad to hear the demo's working for you now.

Take care,
Mark

Ah, my fault for not reading it properly. Thanks for your help!
