我是Linux新手(来自Windows背景).我想了解在运行时如何加载共享对象(.so文件)的细节.根据http://tldp.org/HOWTO/Program-Library-HOWTO/shared-libraries.html,文件/etc/ld.so.conf配置目录以在运行时搜索.so文件.然而,下面显示的实验似乎表明情况并非如此./ usr/local/lib位于/etc/ld.so.conf.d中的一个.conf文件中,但是当我的.so位于/ usr/local/lib中时,在运行时找不到它.相反/ usr/lib 不是由/etc/ld.so.conf配置的,但当我的.so在/ usr/lib中时,它会在运行时找到.

我错过了什么？

谢谢,戴夫
