/MD means link for the C/C++ release, runtime dlls (msvc... dlls
etc). /MDd means link for the C/C++ debug, runtime dll (msvc...d
dlls). /MT means link the C/C++ release, runtime static library
(libc.... libs etc). /MTd means link the C/C++ debug, runtime
static library (libc...d libs). <br>
<br>
If the notes say release is /MT and debug is /MD, that's linking
static release libraries on a release build, and dynamic release
dlls on a debug build. That's a bit unusual, and won't always work
well on a debug build, depending on how exceptions or errors are
handled.<br>
<br>
It's generally not a good idea to mix debug and release runtimes,
and sometimes you can get weird link errors mixing static lib and
dll runtimes, so use only /MT or only /MD everywhere for release,
and only /MTd or only /MDd everywhere for debug. You can't control
what third parties do with their code though. I generally do /MD or
/MDd for the runtimes, because the dll is only loaded once, no
matter how many times it's linked to from anyone's library.<br>
