Re: dllexport template function: char* parameter problem

last week I got the suggestion to write template functions for my error
handling. With the implementation I've got a little problem: As the functions
are in a separate dll, I have to instantiate them explicitely in the cpp
file. This works fine for parameters of type int or double. The main purpose
of my error printing function is to print a message though. But for a
explicit instantiation with a char* parameter, the linker strikes:

// header file:
template <typename T1> void TEMPLDLL_API PrintError(const T1& arg1);

// cpp file:
template <typename T1> void PrintError(const T1& arg1)
{
    cerr << arg1 << endl;
}

// function call:
PrintError("There was an error.");

This causes a LNK2019:

error LNK2019: unresolved external symbol "__declspec(dllimport) void
__cdecl PrintError<char const [20]>(char const (&)[20])" ...

If I now cast the string to a char* the error is
gone: ErrorHandling::PrintError((char*)"There was an error."); // works

This is really ugly though esp. for an overload with several parameters.
More than ever if I do it the clean c++ way with static_cast<char*>("There
was an error");.

Any suggstions?
