Hi Conrad,

Please upgrade to a newer version and try against.

Cheers,

Hi

I have a simple class that rootcint seems to have trouble with when
creating a dictionary file:

class TFileInfo : public TObject {
public:
  const TString name;
  const Int_t mode;
  const Int_t size;
  const Int_t mtime;

  TFileInfo();
  TFileInfo(const char *my_name, const Int_t my_mode, const Int_t my_size,
const Int_t my_mtime):
  name(my_name),
  mode(my_mode),
  size(my_size),
  mtime(my_mtime)
  {}
  virtual ~TFileInfo();
  ClassDef (TFileInfo, 1)
};

The error message is:

webfiledict.C: In method `void TFileInfo::Streamer (TBuffer &)':
webfiledict.C:471: passing `const TString' as `this' argument of `void
TString::Streamer (TBuffer &)' discards qualifiers
webfiledict.C:472: could not convert `TString(this->TFileInfo::mode)'
to `TString &'
/opt/root/include/TString.h:349: in passing argument 2 of `operator>>

&, char *)':
webfiledict.C:496: passing `const TString' as `this' argument of `void
TString::ShowMembers (TMemberInspector &, char *)' discards qualifiers

If I remove the const qualifiers the dictionary compiles fine.

Regards

Conrad
