problem to build demos with VC 6.0

Hi,there:

When I build the ICE demo such as Latency example with VC6.0, it failed,it can not resolve external symbol while linking. But it works with Visual Studio .net.

I checked the project setting: the iced.lib iceutild.lib are there and in the menu tool\option directories tab I set the lib path to the ice lib path,did I miss anything else? Compiling was ok.

The error messages look like this:

Client.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) public: void __thiscall IceProxy::Ice::Object::ice_ping(class std::map<class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >,class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >,struct std::less<class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > >,class std::allocator<class std::basic_string<char,struct std::char
.....

Latency.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) public: bool __thiscall IceProxy::Ice::Object::ice_isA(class std::basic_string<char,struct std::char_traits<char>,class
.......

Thanks!

    This looks to me as if STLport is either not found during compilation, linking, or execution:
    • Make sure that during compilation you have STLport's include/stlport directory in your INCLUDE path. (Note: Just using STLport's include directory won't work.)
    • Make sure that the linker can find the STLport library.
    • Make sure that the STLport DLL is in your PATH.

    Hope this helps!
  • I tried as you said,it still can not work out. I am wondering why it works in Visual studio.net, I didn't install STLport at that time,but it works fine. It's kind of wierd,but anyway I can build it in visual studio.net.

    Thanks!

    Well, with Visual C++ .NET, you don't need STLport. You only need STLport with Visual C++ 6.0.

    Perhaps you mixed Ice libraries compiled with Visual C++ .NET with code compiled with Visual C++ 6.0?
  • Yeah you might make the point. The iced.lib and iceutild.lib I used is from the binary package which is download from your web site,I think it is build in visual studio.net.

    Thanks!

    That's correct. You cannot use the binary package with Visual C++ 6.0. You must compile Ice with Visual C++ 6.0 and STLport.
