This is the Ubuntu package for Standard C++ libraries v5.
Even though it says amd64, this is for both Intel and AMD processors.
If the flavor is debian, the libraries are in the debian package repositories.
To install from the linux server.
Copy the file to the linux machine that will be running the RALUS client.
Run the following command:
sudo dpkg –i libstdc++5_3.3.6-17ubuntu1_amd64.deb
…of course, you know if running as root, you don’t need sudo.
Afterwords, install the RALUS package normally
