  1. If you are compiling something and you want the compiler to search a specific directory, you can add the -L flag. Like this:

    g++ -L /lib64
    
  2. You can also add this directory to the environment variable 'LD_LIBRARY_PATH'. Like this:

    export LD_LIBRARY_PATH="/lib64"
    
  3. You can also use ldconfig to add a directory to the search path. Like this:

    sudo ldconfig /lib64
    
  4. Finally, you can add the directory to /etc/ld.so.conf (and rerun 'sudo ldconfig') to make this change permanent.

    sudo echo "/lib64" >> /etc/ld.so.conf; sudo ldconfig

  • For 4, probably better to add a .conf file to the /etc/ld.so.conf.d directory – Den-Jason May 14 at 12:00
