Hi,

I've a weir problem with BCC linker. This is the error it gives me:

[Linker Error] Unresolved external 'TTagList::GetCount()' referenced
from C:\DEVEL\SFCOMS\SAMPLEAPPS\RIDEL\RIDELDEMO\READALL.OBJ

Well, ReadAll.cpp is a form of an application that contains this:

...

         if ( Tags->Count ) {

...

Now, Tags is an instance of TTagList, defined on TagList.cpp. In the
includes of ReadAll.cpp I've put:

...

#include "TagList.h"

...

But this does not make the matter, as It compiles fine, but it does not
link later.

TTagList has a property that's *public* declared as:


public:

...
         __property int Count = {
                 read=GetCount
         };

Method GetCount for TTagList is declared as:


protected:
         int GetCount (void);


Note that the method is protected, but it should be cause I'm using the
property Count to access this value and it is public.

As I've said, both modules compiles well by separate, the trouble comes
when linking. By other side, I've used that TTagList object from a
component that I'm writting without this problems.

Any ideas?
