cint bug(?): typedef in custom cast operator signature

[Zelzer Sascha]

Hi,

I am trying to generate dictionary information for some classes in our
toolkit. We rely heavily on a (templated) smart pointer implementation
which declares a custom cast operator using a typedef. Unfortunately,
the code generated by cint/makecint does not compile. Using the original
typename works. Here is a reduced testcase:

// ====== begin custom cast operator test ======
template<typename T>
class SmartPointer
{

 public:

  typedef T ObjectType;

  SmartPointer() : m_Pointer(0) {}
  SmartPointer(ObjectType* p) : m_Pointer(p) {}

  /** Return pointer to object.  */
  operator ObjectType * () const
  //operator T * () const // this works!
    { return m_Pointer; }

 private:

  ObjectType* m_Pointer;
};

class Dummy
{
};

SmartPointer<Dummy> sp;
// ====== end custom cast operator test ======

Typing

makecint -mk Makefile -dl cco -H custom_cast_operator.cpp
make

fails with svn revision 27119 and gcc 4.1.2. Is this a limitation or a
bug?

Regards,
Sascha

Hi Sascha!

Thanks for the report! I will check during the second half of the week,
and I agree that this seems to be a name lookup issue.

Cheers, Axel.
