如何显示动态库的的依赖关系

X86环境下：

root@192.168.1.197:/usr/bin#ldd /usr/lib/libglib-2.0.so

linux-gate.so.1 => (0x00ccc000)

libpcre.so.3 => /lib/libpcre.so.3 (0x00110000)

libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0x0054a000)

/lib/ld-linux.so.2 (0x00840000)

ARM环境下，显示交叉编译出来的的动态共享库的依赖关系

root@192.168.1.197:/root/Qt/output/qt-arm/lib#arm-none-linux-gnueabi-readelf -d libQtCore.so

显示依赖关系的命令 ***readelf 和交叉编译器有关：

或用 arm-linux-readelf -d *.so
