Calling static member function from non-class function

[djwhy]

I'm having trouble calling a static class member function (that returns a pointer to a singleton) from a non-class function. When I try to compile (with mingw gcc) I get an error. The problem code is below:

 void executer(void* params)
 {
    FunctionParameters* args = static_cast<FunctionParameters*>(params);

    std::string name = (*args)[0];

    TFunctor* func = IConsole::interface()->getCommand(name);

    if(func != 0)
        func->Call(args);
    else
        IConsole::interface()->add("Function Not Found");
 }

The code works well from inside the IConsole class but but i need to pull it out so that i can eventually run it as a pthread. If I pass the pointer to IConsole to the function like so:

void executer(void* params, IConsole* con)
{
    FunctionParameters* args = static_cast<FunctionParameters*>(params);

    std::string name = (*args)[0];

    TFunctor* func = con->getCommand(name);

    if(func != 0)
        func->Call(args);
    else
        con->add("Function Not Found");
}

everything works perfectly, except i can't use this to start a pthread. The IConsole->interface() call is used excessively throughout the many classes in the program without any trouble but always from inside a class. Is there some trick to calling the static class member function from a non-member class.

Any Ideas greatly appreciated.
