Re: build error -- can not find operator new

Thanks for your description Brian, yes, I agree that it should be during link time when the runtime shared lib (with libc or libc++) is considered to choose.

When you invoke the compiler as gcc, it will treat filenames ending in
.cpp/.cxx/.cc/.C as C++ for the purposes of choosing what language to
interpret the source as, but it will *not* add the necessary runtime
support when linking.  You only get that when you link using g++,
regardless of filenames, since at that point you're dealing with objects
not source files anyway.
