ldd是用来查看共享库依赖的Shell脚本命令。下面来看一下ldd命令的参数。 [C++] 使用ldd

  • -v：显示所有信息，例如包括符号版本信息。
  • -u：显示没有使用的直接依赖。
  • -d：执行重新定位，报告任何缺失对象（仅针对ELF）
  • -r：对数据对象和函数执行重新定位，报告任何缺失对象或函数（仅针对ELF）

Oracle - Linker and Libraries Guide - Relocations介绍了重新定位技术的来龙去脉，也介绍了ldd命令的相关使用。

ld-Linux.so

ldd显示可执行模块的dependency的工作原理，其实质是通过ld-Linux.so（elf动态库的装载器）来实现的。我们知道，ld-linux.so模块会先于executable模块程序工作，并获得控制权，因此当上述的那些环境变量被设置时，ld-linux.so选择了显示可执行模块的dependency。 直接执行ld-Linux.so命令也可获得共享库的依赖关系：

hadoop@node51054:/usr/bin$ /lib64/ld-linux-x86-64.so.2 --list ./curl
