VS2005 Linking problem std::_String_base::_Xran

Hello,
I trying to build my project in VS8 (it was building fine in VS2003).
I get these linking error :

engine.lib(ECMFileHandler.obj) : error LNK2001: unresolved external symbol "public: void __thiscall std::_String_base::_Xran(void)const " (?_Xran@_String_base@std@@QBEXXZ)

engine.lib(ECMFileHandler.obj) : error LNK2001: unresolved external symbol "public: void __thiscall std::_String_base::_Xlen(void)const " (?_Xlen@_String_base@std@@QBEXXZ)

engine.lib(ECMFileHandler.obj) : error LNK2001: unresolved external symbol "public: void __thiscall std::ios_base::_Addstd(void)" (?_Addstd@ios_base@std@@QAEXXZ)
I checked to make sure all my projects are compiled in MT debug.

Here are the command line of the linker for my projects:

I have been adding different libs to the configuration and searching on google with no success...
I hope someone can tell me what is going on !

Thanks

Hmm: I think I might know what is going on here. A dump of the symbols in the libcpmtd.lib that ships with Visual C++ 2005 show the following definition for Xran

131 00000000 SECT62 notype () External | ?_Xran@_String_base@std@@SAXXZ (public: static void __cdecl std::_String_base::_Xran(void))

Notice how it is a __cdecl function and the error message you are seeing states that it is a __thiscall function.

Also if I look at the current definition of _String_base (which is in the xstring header file) I see the following:

class _CRTIMP2_PURE _String_base : public _Container_base
{
public:
_MRTIMP2_NPURE_NCEEPURE static void __CLRCALL_PURE_OR_CDECL _Xlen();
_MRTIMP2_NPURE_NCEEPURE static void __CLRCALL_PURE_OR_CDECL _Xran();
_MRTIMP2_NPURE_NCEEPURE static void __CLRCALL_PURE_OR_CDECL _Xinvarg();
};

For a native compilation __CLRCALL_PURE_OR_CDECL should map to __cdecl.

If I was you I would take a look at your definition of _String_base and check that the member function declarations use the __CLRCALL_PURE_OR_CDECL macro and if they don't then you might want to make them explicitly __cdecl as I note that you do not appear to be compiling for the CLR.

I had the same problem when convertin Crypto51/523 library from VS2003 to VS2005. I figured out that newly built cryptolib.lib went to different folder and the main app was trying to link to old .lib file. As soon as paths were fixed the issue resolved.

I'm having this same problem. The linker output says __thiscall instead of __cdecl. If the linker is showing __thiscall, but it should be __cdecl, why is the linker doing this? Which library should Xran be found in?

Did you ever figure this out? I'm encountering the same issue...

I got rid of this problem by just doing a "Rebuild All" of my project.

Hi,

I have the same problem...I am new to VC++...Here are the errors

dSSTSDKsul.lib(hex.obj) : error LNK2001: unresolved external symbol "public: void __thiscall std::_String_base::_Xran(void)const " (?_Xran@_String_base@std@@QBEXXZ)

1>dSSTSDKsul.lib(oaep.obj) : error LNK2001: unresolved external symbol "public: void __thiscall std::_String_base::_Xran(void)const " (?_Xran@_String_base@std@@QBEXXZ)

From your explanation above i see that the function call should be _cdecl instead of _thiscall.But i don't know how to change it...

Pls help me out.

Thanks
