ld编译选项-rpath和-rpath-link的区别

如资料¹所述：

The difference between -rpath and -rpath-link is that directories specified by -rpath options are included in the executable and used at runtime, whereas the -rpath-link option is only effective at link time.

1. -rpath-link 只影响静态编译的链接阶段
2. -rpath 还会影响动态运行阶段。它会把路径写到ELF文件的DT_RPATH标记里面，从而影响动态链接器ld.so寻找共享库的过程，但是ld.so的manual不建议这么做。
