Where?  Can you please explain why this is needed?  What error message

Did you search .o files?  They are mangled symbol names.  You'll
probably need to use something like

  for f in *.o ; do echo $f ; nm $f | grep get_size__Ct6Array21Zcii ; done

to find them.

I think most of these symbols should be defined in the files like
Array-C.o that are used to hold the explicit instantiation of template
classes.
