Install GAUSS for Linux

If you choose to install GAUSS in a directory which does not have write permissions for normal user accounts such as /opt or /usr/local, then you must choose the Advanced Installation and Multi-User Installation options during installation.

Extract and Copy Installer Files

Pre-GAUSS 17

  1. Open a terminal window; this normally starts in the user's home directory. If not, change directories to that location or where you want GAUSS installed and make a gauss16 directory with the command:

    mkdir gauss16

  2. Copy the downloaded file from where it was saved (usually under the user's home directory in the Downloads folder) to the new gauss16 folder. The downloaded file should be named GAUSS_16_Linux_amd_64.tar.gz (or similar depending on the flavor of Linux being installed).
  3. Next enter

    tar xvf GAUSS_16_Linux_amd_64.tar.gz

GAUSS 17 and later

  1. In a terminal window, cd to where you'd like to install GAUSS (e.g., /home/user). A top level directory will automatically be created during the extraction process.
  2. Copy the downloaded file from where it was saved (usually under the user's home directory in the Downloads folder) to the User's home folder. The downloaded file should be named GAUSS_19_Linux_64.tar.gz.
  3. Next enter

    tar xvf GAUSS_19_Linux_64.tar.gz

Run the installer

  • Run the installer from a terminal window by entering:


  • A message will appear asking you to Choose installation type: [D]efault, [A]dvanced [Q]uit
    • The default option will install everything under the current directory.
    • The advanced installation allows you to choose a single-user or multi-user installation and also allows you to place the shared libraries that GAUSS depends on in another location.
    • If you choose a multi-user installation, the binaries and most of the rest of the installation will reside in the current directory. Each time a new user starts GAUSS on this machine, GAUSS will create a local working directory for that user under the user's home directory. The local working directory will contain the files and folders that which may be customized by the user. This allows the admin to install GAUSS in a location without universal write privileges. No files will be placed under the home directory of any user who does not start GAUSS.
    • Enter a letter to choose an installation type.
  • A copy of the license agreement for GAUSS will be displayed; press Enter to advance line by line, press the space bar to advance by page. When you are ready, enter "yes" to accept the license agreement and continue.
  • Follow the instructions given by the installation script.
  • Put the installation directory for GAUSS in the executable path and in the shared library search path.
