错误:ld.so:无法预加载对象LD_PRELOAD:已忽略 [英] ERROR: ld.so: object LD_PRELOAD cannot be preloaded: ignored

问题描述

我正在使用ubuntu 12.04.每次启动bash终端时，以及每次键入命令(并按Enter)时，都会收到以下消息:

I am using ubuntu 12.04. Every time I start my bash terminal and every time when I finish typing a command(and press enter) , I get this message:

错误:ld.so:来自的对象'/usr/lib/liblunar-calendar-preload.so'LD_PRELOAD无法预加载:被忽略.

ERROR: ld.so: object '/usr/lib/liblunar-calendar-preload.so' from LD_PRELOAD cannot be preloaded: ignored.

这很奇怪.那么，环境变量LD_PRELOAD的作用是什么?幕后到底是怎么回事?

It is weird. So what is the environment variable LD_PRELOAD used for? And what is the going on behind the scene?

谢谢.

推荐答案

链接器考虑了一些环境变量.一个是 LD_PRELOAD

The linker takes some environment variables into account. one is LD_PRELOAD

来自 man 8 ld-linux :

LD_PRELOAD
          A whitespace-separated list of additional,  user-specified,  ELF
          shared  libraries  to  be loaded before all others.  This can be
          used  to  selectively  override  functions   in   other   shared
          libraries.   For  setuid/setgid  ELF binaries, only libraries in
          the standard search directories that are  also  setgid  will  be
          loaded.

因此，链接器将在加载其他库之前尝试加载 LD_PRELOAD 变量中列出的库.

Therefore the linker will try to load libraries listed in the LD_PRELOAD variable before others are loaded.

在变量内部列出无法预加载的库的情况可能是什么.在设置了 LD_PRELOAD 的 .bashrc 或 .bash_profile 环境中查看，然后从变量中删除该库.

What could be the case that inside the variable is listed a library that can't be pre-loaded. look inside your .bashrc or .bash_profile environment where the LD_PRELOAD is set and remove that library from the variable.
