linux下如何设置环境变量LD_LIBRARY_PATH [英] How to set the environmental variable LD_LIBRARY_PATH in linux

问题描述

我先执行了命令:export LD_LIBRARY_PATH=/usr/local/lib

然后我打开了.bash_profile 文件:vi ~/.bash_profile.在这个文件中，我把:

Then I have opened .bash_profile file: vi ~/.bash_profile. In this file, I put:

LD_LIBRARY_PATH=/usr/local/lib
export LD_LIBRARY_PATH

然后如果终端关闭并重新启动，输入 echo $LD_LIBRARY_PATH 不会显示任何结果.

Then if the terminal is closed and restarted, typing echo $LD_LIBRARY_PATH displays no result.

如何永久设置路径?

推荐答案

你应该添加更多关于你的发行版的细节，例如在 Ubuntu 下正确的方法是添加一个自定义的 .conf文件到/etc/ld.so.conf.d，例如

You should add more details about your distribution, for example under Ubuntu the right way to do this is to add a custom .conf file to /etc/ld.so.conf.d, for example

sudo gedit /etc/ld.so.conf.d/randomLibs.conf

在文件中，您应该写入包含您希望添加到系统的所有库的目录的完整路径，例如

inside the file you are supposed to write the complete path to the directory that contains all the libraries that you wish to add to the system, for example

/home/linux/myLocalLibs

记住只添加目录的路径，而不是文件的完整路径，该路径内的所有库都会被自动索引.

remember to add only the path to the dir, not the full path for the file, all the libs inside that path will be automatically indexed.

保存并运行 sudo ldconfig 以使用此库更新系统.

Save and run sudo ldconfig to update the system with this libs.
