How can the default dynamic library loading path be changed in Linux?

There are several ways to change the default dynamic library loading path in Linux.

1. By utilizing environment variables, the default dynamic library loading path can be changed by setting the LD_LIBRARY_PATH environment variable. For instance, the path can be altered by executing the following command in the shell:
2. Set the LD_LIBRARY_PATH to include the new library directory before the existing LD_LIBRARY_PATH.
3. This will add the new path to the default dynamic library loading path in the current shell session. To permanently change the default path, you can add the above command to the .bashrc or .profile file.
4. To specify the search path for dynamic libraries in a Linux system, you can use the /etc/ld.so.conf file. Simply add a new path to the file, and then run the ldconfig command to apply the changes. For example, open the ld.so.conf file, add the new path /path/to/new/library/directory, save the file, and then run the command.
5. Run ldconfig with elevated privileges.
6. In addition to using the /etc/ld.so.conf file, you can create new configuration files in the /etc/ld.so.conf.d directory to specify dynamic library loading paths. Create a new file in this directory, such as mylib.conf, and add the new path /path/to/new/library/directory in the file. Save the file and then run the sudo ldconfig command to apply the changes.

Please be aware that changing the default dynamic library loading path may cause issues with other applications or libraries on the system, so it is important to carefully consider and understand the potential consequences before making any changes.
