Installing GAUSS for LINUX

NOTE: 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 the files

The first step is to extract the files to the folder where GAUSS will be installed, usually gauss16 under the user's home directory (/home/user/gauss16). 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

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). Extract the file in that location by entering

gunzip GAUSS_16_Linux_amd_64.tar.gz

Next enter

tar -xvf GAUSS_16_Linux_amd_64.tar.

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.

This 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. Then 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.

Request your permanent license

Unless you already have a permanent license on your machine, a file named myhostid.txt will be created in directory where you installed GAUSS. To request your GAUSS license, fill out this form. The final line of myhostid.txt contains the hostid of your computer which you will need for your license request. If you have already closed your text editor, you will find the myhostid.txt file in your GAUSS installation directory. You may either copy and paste the contents or attach the myhostid.txt file.

GAUSS comes with a temporary license that allows you to run GAUSS for a few days, so that you do not have to wait for your permanent license to begin using GAUSS.

- Install your permanent license: Single User License When you receive your permanent license, simply place it in the directory in which GAUSS 16 is installed.

- Verify your license: To confirm that your license file is installed correctly:
- Start GAUSS
- From from the main application menu bar select: Help->About GAUSS.

About GAUSS window

The license type field will tell you if you are using a permanent or temporary license.


Problem: When I try to run GAUSS, I get a dialog window that says "License Manager Error".

Answer: This means that your temporary license has expired and GAUSS cannot locate your permanent license. Browse to your GAUSS installation directory and check to see if you have a license file in that directory other than the temporary license. GAUSS license files end with a .lic extension.

If you have received your permanent license and cannot find it in the GAUSS installation directory, copy it there now and restart GAUSS.
