Hi Tony,
It's kinda of odd that the line in osgconv.cpp:
if (dynamic_cast<osgViewer::GraphicsWindow*>(_gc.get()))
Doesn't for the symbol GraphicsWindow to be imported and there for
osgViewer linked properly, perhaps this is a bug in the linker.
Referencing something benign like osgViewer::osgViewerGetLibraryName()
is a bit obscure relatively harmless if one comments why its there.
I'd rather getting using something useful in osgconv for this purpose
though.
Robert.
