ldd

ldd [option] file

List dynamic dependencies; that is, list shared objects that would be loaded if file were executed. (If a valid file needs no shared objects, ldd succeeds but produces no output.) In addition, ldd's options can be used to show unresolved symbol references that would result from running file. Specify only one option.

Options

-d

Check references to data objects only.

-r

Check references to data objects and to functions.
