Your system does not have a lot of virtual memory Compiling <%= PROGRAM_NAME %> works best when you have at least <%= @required %> MB of virtual memory. However your system only has <%= @current %> MB of total virtual memory (<%= @ram %> MB RAM, <%= @swap %> MB swap). It is recommended that you temporarily add more swap space before proceeding. You can do it as follows: sudo dd if=/dev/zero of=/swap bs=1M count=1024 sudo mkswap /swap sudo swapon /swap See also https://wiki.archlinux.org/index.php/Swap for more information about the swap file on Linux. If you cannot activate a swap file (e.g. because you're on OpenVZ, or if you don't have root privileges) then you should install <%= PROGRAM_NAME %> through DEB/RPM packages. For more information, please refer to our installation documentation: <%= @install_doc_url %> Press Ctrl-C to abort this installer (recommended). Press Enter if you want to continue with installation anyway.
