Yes, you're definitly right. As much as I like to find answers while
searching in archives or whatnot, I really should've provided some more
info on this.
Problem is: As I have all changes already commited to our repository and
I have no build-log around, I can not fully re-produce the problem with
complete error messages.
(In upcoming problems - and I'm sure they'll come around ;) - I'll try
to keep more "input" around!)
At least I can tell, what I did:
I switched the whole package to using forward declarations exclusively
in all headers.
Also I found that there where a lot of typedefs for the templates across
many headers, which got included by many cpp-files, so I moved them to
the cpp-files, too. I'm not sure, whether a line like
typedef cTplSet<G_edge> cEdgeSet;
in a header included by many cpp-files causes these "multiple
definition" error, but it's working now.
Sorry again that I have no error logs around anymore...
regards,
Florian
