initialization of static const variables fails

[WinniePooh]

Hi there, I've the following code (here a snippet).

/////////////////////////////////
// *.h file
/////////////////////////////////
class ParameterTypeNames
{
public:
    static const std::string FLOAT;
    static const std::string INT;
    // ...
private:
    inline ParameterTypeNames() {};
};
 
 
/////////////////////////////////
// *.cpp file
/////////////////////////////////
const std::string ParameterTypeNames::FLOAT = "Float";
const std::string ParameterTypeNames::INT   = "Int";
// ....
 
 
/////////////////////////////////
// usage of the constants in a constructor of other class
/////////////////////////////////
// ...
std::string s = ParameterTypeNames::FLOAT;
// ...

In the last line (where the constant is actually being used), s holds an empty string, which I don't quite understand. Why is s not "Float"?? I thought that my initialization is correct.

Btw, I'm using VC 8.0 and it was in debug mode, if that is of any importance here.

I'd be happy about suggestions :-).

Greetings,
Felix

frnd i m not sure
but try this

class ParameterTypeNames
{
public:
static const std::string FLOAT="FLOAT";
static const std::string INT="INT";
// ...
private:
inline ParameterTypeNames() {};

hi, I have compiled your code and add a main() function:

int main(int argc, char** argv)
{
std::cout<<s<<std::endl;
return 0;
}

and the result I get is "Float", so it seems normal on my machine and I think your code is correct ...

btw, I'm using VS2005...
