error while loading shared libraries: libncurses.so.5

This error typically occurs when a program or package depends on the libncurses.so.5 library, but it is not installed or is not in the expected location.

To resolve this issue, you can try the following steps:

1. Check if the library is installed on your system by running the following command:

   sudo ldconfig -p | grep libncurses.so.5

If the library is not found, you may need to install it. On Ubuntu or Debian-based systems, you can do this with the following command:

   sudo apt-get install libncurses5

2. If the library is installed but not in the default location, you can create a symbolic link to it. For example, if the library is located in /usr/local/lib, you can create a symbolic link to it with the following command:

   sudo ln -s /usr/local/lib/libncurses.so.5 /usr/lib/libncurses.so.5

This command creates a symbolic link from /usr/lib/libncurses.so.5 to /usr/local/lib/libncurses.so.5.

3. If none of the above steps work, you may need to update your LD_LIBRARY_PATH environment variable to include the directory where the libncurses.so.5 library is located. For example, if the library is located in /usr/local/lib, you can add the following line to your .bashrc file:

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

This command adds /usr/local/lib to the beginning of the LD_LIBRARY_PATH variable, so that the system looks for libraries in that directory before looking in the default locations.

After performing any of these steps, try running the program again to see if the error has been resolved.
