Your posting contains to random lines from an unknown config.log and a
g++ command presumably supposed to compile some C++ source code file
and link it in order to create an executable binary from it which
failed because the link editor couldn't find all required symbols.

This leaves an interesting question open, namely "What's your
question?".
