linux下查看程序的依赖库

x86情况下：ldd

           例如：#ldd ffplay

 libavdevice.so.53 => /usr/local/lib/libavdevice.so.53 (0x00b27000)
 libavfilter.so.2 => /usr/local/lib/libavfilter.so.2 (0x00dd6000)
 libavformat.so.53 => /usr/local/lib/libavformat.so.53 (0x00398000)
 libpthread.so.0 => /lib/tls/i686/cmov/libpthread.so.0 (0x0062a000)
 libx264.so.128 => /usr/local/lib/libx264.so.128 (0x007fe000)
 libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0x00b46000)
 /lib/ld-linux.so.2 (0x005c4000)
