Subject: [ROOT] operator in a namespace question




  Hello Rooters.

    I am using ROOT cvs from Monday 4/11 on LINUX.  My question is this,
  I have a the following class:

namespace FOO{

  class bug{
  private:
    int i;
    
  public:

    bug(int j);
    int get();
    void set(int j);
    friend bug operator+(const bug& rhs, int c);
  };
};


Using the following LinkDef.
#ifdef __CINT__

#pragma link off all globals;
#pragma link off all classes;
#pragma link off all functions;

#pragma link C++ namespace FOO;
#pragma link C++ nestedclasses;

#pragma link C++ class FOO::bug-!;
#pragma link C++ function FOO::operator+(const bug&, int);
#endif

It compiles fine, but when I go to use it, I get the following problem:

root [0] FOO::bug c(10)
root [1] c.get()       
(int)10
root [2] c+10          
Error: operator+ not defined for FOO::bug FILE:(tmpfile) LINE:1
*** Interpreter error recovered ***
root [3] using namespace FOO
root [4] c+10               
(class FOO::bug)146564000
root [5]     

Attached are the files (along with the .cxx).  I know that not using a
namespace would be easier, but in this case, I am constrained to using
one.  Any help will be appreciated. 

This is of course the usual stripped down version of a complicated
problem! :-)

Thanks.
