[ROOT] static map

Dear ROOTers,

I have the folowing class:
#include <map>
#include <string>
#include <TObject.h>
#include "TStyle.h"

class CError : public TObject {
public:
  CError() {};
  ~CError() {};
  inline void werf(string msg);
 
 private:
  static Int_t count; 
//static map<string,Int_t> messages;
  map<string,Int_t> messages;
 
 ClassDef(CError,0) 
};
Int_t CError::count = 0;

inline void CError::werf(string msg) {
    messages["hallo"] = 1;  // does only work in the non static case !
}

It works fine like this. But I wont to have the static map. Changing it 
to static results in:

CError_C.so: undefined symbol: _6CError.messages

What works for the integer does not seem to work for map.
Does anyone  have a solution for that?

Regards,
Claus Horn
