 # `_DEBUG`
 
-The compiler defines `_DEBUG` when you specify the /MTd or /MDd option. These options specify debug versions of the C run-time library.
+The compiler defines `_DEBUG` when you specify the [`/MTd`](../build/reference/md-mt-ld-use-run-time-library.md), [`/MDd`](../build/reference/md-mt-ld-use-run-time-library.md), or [`/LDd`](../build/reference/md-mt-ld-use-run-time-library.md) option.
