I'm not sure I've been undertand how the traverse method works...
If I want to write a simple EditVisitor that only parse the graph and print,
for each node, something like "found a node of this type: ......." and this
way...
I've written this class:
class EditVisitor : public osg::NodeVisitor
{
public:
EditVisitor() {}
virtual void apply(osg::Node& node)
{
osg::notify(osg::NOTICE)<<"...EditVisitor: NODE found '" <<
node.getName() << "'" << std::endl;
traverse(node);
}
virtual void apply(osg::Geode& node)
{
osg::notify(osg::NOTICE)<<"...EditVisitor: GEODE found '" <<
node.getName() << "'" << std::endl;
traverse(node);
}
virtual void apply(osg::Group& node)
{
osg::notify(osg::NOTICE)<<"...EditVisitor: GROUP found '" <<
node.getName() << "'" << " (" << node.getNumChildren () << " figli)" <<
std::endl;
for (unsigned int i = 0;i< node.getNumChildren (); i++)
{
osg::notify(osg::NOTICE)<<" ..."<< i << "° figlio:"
<< std::endl;
osg::ref_ptr<osg::Node> nd = node.getChild(i);
if( nd.valid() )
traverse(nd.get());
else
osg::notify(osg::NOTICE) << "Error no valid child
added." << std::endl;
}
traverse(node);
}
};
but, during compilation, it give me this error:
make[1]: Entering directory
`/home/leo/OSG/sources/OpenSceneGraph/applications/osgvisitor/Linux32.Opt'
g++ -O2 -W -Wall -fPIC -pipe -I../../../include -I/usr/X11R6/include -c

make[1]: *** [osgvisitor.o] Error 1

can anybody explain this error to me?
thanks leo
