It sounds like you're a little confused.
Between C++ objects and object files? Whether two object files
are binary compatible makes sense as a question.
Binary compatablity usually is associated with a context.
It is usually associated with compiler output: object files and
libraries. If two files are object compatible, they can be
linked together and will work as expected. (I know you know
that, but I think it's the answer to the question the original
poster tried to ask.)
If you build with different versions of the STL or with
various options that render binary incompatibility, then this
is your choice.
If you're using third party libraries, you don't always have a
choice. You have to compile with whatever options are necessary
to ensure binary compatibility with what they furnish. (For
starters, this usually means compiling with CC, and not g++.)
