LD_ LIBRARY_ Path environment variable setting

LD_LIBRARY_PATH yes Linux environment variable name , This environment variable is mainly used to specify the search of shared libraries （ Dynamic link library ） In addition to the default path .

A lot of software doesn't root Permission installation will be difficult , Mainly because of various system library files , That is to say LD_LIBRARY_PATH The files in this environment variable .

We can do it in  ~/.bashrc  perhaps  ~/.bash_profile  Add export sentence , The former in every login and every open shell Read once , The latter is read only once when logging in . My habit is to add  ~/.bashrc  in , At the end of the file , The following statement can be used to make the setting effective ：

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

I put it on ~/.profilel Inside ,

bash as a login shell doesn't parse .profile if either .bash_profile or .bash_login exists. From man bash :

it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable.

After modification , Remember to turn off the current terminal and reopen a new terminal , So that the above configuration takes effect .
