title: Building for macOS, but linking in object file built for free standing
body: <p>I am building ffmpeg and I get the following error for several files. I am not specifically building with the free standing flag, so cannot see why this is happening. What does it actually mean? Is there a problem with it, or is it an ignorable warning? If there's a problem, does anyone have any idea how to fix it?</p>
