Hi Paul,
osganimationtimeline fails to build on VC 2005. See attached error log.
It builds for me. Perhaps you had a partial update, because
osganimationtimeline.cpp revision 10697 seems to contain the
modifications to include the necessary header to fix your error.
About the warnings. I haven't used virtual inheritance, only read about
it in books, but to me it looks like the fact that
osgAnimation::AnimationUpdateCallbackBase inherits virtually from
osg::Object should tell the compiler that that version of the methods
take precedence over other classes inherited only publicly. So I think
this warning is bogus.
Before we decide to suppress warning C4250 though, could someone with
more knowledge/experience than me check to see that it's all ok?
Just to summarize, this is the situation:
class Base : public virtual osg::Object {};
template<class T>
class Derived : public Base, public T {};
(where T is also derived from osg::Object just as Base was - in this
case T is osg::NodeCallback).
The warning is saying that the same members are being inherited from
Base and T, and I think the virtual qualifier when Base inherits from
osg::Object should fix the ambiguity and should mean that the members
from Base should win. Obviously the virtual seems to remove the
ambiguity since this is a warning and not an error, so I think this
warning is just a case of VC++ trying to warn the programmer of
something he already knows...
