<DIV><FONT face="Bookman Old Style">You use new and old iostream in your program
simultaneously. You use Cmaker to configure vtk withought enable ansi iostream,
so vtk use old iostream, but you include new iostream in your program. If you
using namespace std, compiler will cannot distinguish the new and old iostream,
so ambiguous symbol is reported. </FONT></DIV>
<DIV><FONT face="Bookman Old Style"></FONT> </DIV>
<DIV><FONT face="Bookman Old Style">You can configure to use the new iostream
using CMaker and rebuild vtk.</FONT></DIV>
