Problems and Workarounds from Sun Workshop[tm] 6 update 2 C++ Compiler Read

Question

Hello out here,
the Sun Workshop[tm] 6 update 2 C++ Compiler Readme says
in Chapter E. Problems and Workarounds
and
Topic 4. Reference From Template to Non-Global File-Scope object is Not Supported:
A program using templates and static objects causes link-time errors of undefined
symbols. The compiler currently does not support reference to non-global file-scope
objects from templates.
So my problem is:
I have static tyname objects in Templates and get that link-time errors of undefined
symbols.
And I do not know how to get rid of that static typename objects.
Is there a Workaround?
Which?
P l e a s e h e l p.
If you need further information, please let me know.
Any help is appreciated.
Thanks in advance.
Yours truly
Karsten J. Martin

Answer 1

Hello,
Thank you for your detailed answer!
Unfortunately there has arosen another problem while
migrating from 4.2 to SunWorkshop[tm] 6 update 2 C++ Compiler.
Here comes the original(4.2) code:
template <class PersistObject>
class DIDDatabaseInterface : public DIDPersistenceInterface<PersistObject>
private:
     DIDTableObject<PersistObject>     m_tableObject;
public:
It does not compile under Version 6.
Now the new version:
template <class PersistObject>
class DIDDatabaseInterface : public DIDPersistenceInterface<PersistObject>
private:
typedef     DIDTableObject<PersistObject> PersistTable;
static typename DIDDatabaseInterface::PersistTable m_tableObject;
public:
That compiles until...
"did_factory.cc", line 73: Information: Instantiating DIDDatabaseInterface<Devx003>::DIDDatabaseInterface(const RWDBConnection&)
"did_persist.cc", line 81: DIDDatabaseInterface<Devx003>::m_tableObject cannot be initialized in a constructor.
Here comes line 81 and surroundings(compiles under 4.2):
template <class PersistObject>
DIDDatabaseInterface<PersistObject>::DIDDatabaseInterface(const RWDBConnection &c)
     :     DIDPersistenceInterface<PersistObject>(),
          m_tableObject(c)
Any idea?
I would be grateful if you could help.
Thank you so much.
Sincerely yours
