We are porting our existing MC++ library from VS 2003 to VS 2005. The library
is using Tibco, and somehow VS 2005 during compilation gives linker error.
there is no change in project settings. The following are the error msg

Error    1    error LNK2028: unresolved token (0A00002B) "public: class
TibrvStatus __thiscall TibrvMsg::convertToString(char * &)"

Some Additional info.

we did a dumpbin of tibco library and the mangled function name we noticed is

?convertToString@TibrvMsg@@QAE?AVTibrvStatus@@AAPBD@Z
whereas the linker is looking for
?convertToString@TibrvMsg@@$$FQAE?AVTibrvStatus@@AAPAD@Z

the only difference between two function is addition of letter F... can
someone shed light
on this .. Thx for your help

Some more additional info.

In VS 2003 the MC++ project was configured to
Runtime Library : Multi-Threaded - /MT switch
CLR Support - /clr:oldsyntax switch

however, when we compile the same project in VS 2005 we get the following
error

/MT and /clr:oldsyntax incompatible..

then we changed the runtime library to : /MD switch and linker started
giving below error msg.

this is surely a compatibility problem.

Is it perhaps due to the /Zc option that makes wchar_t a native type
by default with VS2005?
