Hi,
I have two sets of classes, both have their own dictionary generated
seperatly. Everything works fine. I'm using Root 3.06.
Now I add a namespace for all my classes. I change both linkdefs to the
following (here's just one linkdef, the other looks the same, just with
other classes):
---
#ifndef _INCLUDE_LINKDEF
#define _INCLUDE_LINKDEF
#ifdef __CINT__
#pragma link off all globals;
#pragma link off all classes;
#pragma link off all functions;
#pragma link C++ nestedclass; // added for namespace
#pragma link C++ nestedtypedef; // added for namespace
#pragma link C++ namespace d0nau; // added for namespace
#pragma link C++ class d0nau::TEventSample-;
#pragma link C++ class d0nau::TEventSampleInfo+;
#pragma link C++ class d0nau; // added for namespace
#endif
#endif
---
Now that works fine for writing the data (Streamer out). But when reading
the data back (within another program, linking against the same class
library with the same dictionaries as the streamer out program) I get the
following errors (with the output from TClassTable above to prove that Root
knows the classes):

The ClassDef/Imp macros look like this:
namespace d0nau{
...
ClassDef( TEventSample, 1 )
...
};
using namespace d0nau;
ClassImp( TEventSample )
This doesn't help:
ClassImp( d0nau::TEventSample )
using namespace d0nau;
nor does this:
ClassImp2( d0nau, TEventSample )
using namespace d0nau;
So what's the right way to do it? What might be wrong here? Why does
streamer out work (and it does, I have some streamer stats that tell me how
often a streamer has been called for a certain class, and my classes have
member classes, and their streamers are called correctly, too, so the whole
ShowMembers->Streamer stuff works) but not Streamer in? I had a look at the
map file: All the methods I expected to exist do exist, even with the
correct namespace. So how can I debug this? How can I find out what's wrong
and what's going on?
Thanks for any help in advance,
regards, Axel.
