I am new to Linux and I want to add lib64/librt.so.1 to the linker command line. Can anyone suggest how to do this? Thanks in advance

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.d/mylibs.conf (and rerun sudo ldconfig) to make this change permanent.

   echo "/lib64" | sudo tee -a /etc/ld.so.conf.d/mylibs.conf; sudo ldconfig
