error while loading shared libraries: libgsl.so.0: cannot open shared object file: No such file or d

本文详细介绍了如何使用find命令定位libgsl.so.0文件,提供了两种解决方案:临时通过修改LD_LIBRARY_PATH环境变量,或永久性地在/etc/ld.so.conf中添加库路径并运行ldconfig。这将帮助读者解决因库文件缺失导致的运行错误。

First, you need to locate the file (libgsl.so.0). You can do this, for example, by using the findcommand:

sudo find / -name "libgsl.so.0"

Let us assume, the file is located in /usr/local/lib. (If the file has not been found, install the corresponding package or download the source, build it and install it.) Now, you have two options:

(1) Quick & Dirty:

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export LD_LIBRARY_PATH

This adds the path of the library to an environment variable. The disadvantage of this option is, that it is only valid for the current session. It will not work for other users. It will not work once you log off and on again.

(2) Permanent:

Review your /etc/ld.so.conf. If /usr/local/lib is not listed there, add it. Now, run ldconfigto detect the shared object file and add it to some system-wide index.
