这个问题你自己man一下不就知道了？

DESCRIPTION
       ldd  prints  the  shared  objects (shared libraries) required by each program or shared object specified on the command
       line.  An example of its use and output is the following:

           $ ldd /bin/ls
               linux-vdso.so.1 (0x00007ffcc3563000)
               libselinux.so.1 => /lib64/libselinux.so.1 (0x00007f87e5459000)
               libcap.so.2 => /lib64/libcap.so.2 (0x00007f87e5254000)
               libc.so.6 => /lib64/libc.so.6 (0x00007f87e4e92000)
               libpcre.so.1 => /lib64/libpcre.so.1 (0x00007f87e4c22000)
               libdl.so.2 => /lib64/libdl.so.2 (0x00007f87e4a1e000)
               /lib64/ld-linux-x86-64.so.2 (0x00005574bf12e000)
               libattr.so.1 => /lib64/libattr.so.1 (0x00007f87e4817000)
               libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f87e45fa000)

       In the usual case, ldd invokes the standard dynamic linker (see ld.so(8)) with the LD_TRACE_LOADED_OBJECTS  environment
       variable  set  to 1.  This causes the dynamic linker to inspect the program's dynamic dependencies, and find (according
       to the rules described in ld.so(8)) and load the objects that satisfy those dependencies.   For  each  dependency,  ldd
       displays  the location of the matching object and the (hexadecimal) address at which it is loaded.  (The linux-vdso and
       ld-linux shared dependencies are special; see vdso(7) and ld.so(8).)
