Installing ENVI

To download and install ENVI:

1. Choose a place to install ENVI on your system and change to that directory. The default installation path is /usr/local/itt.
   
   If you need to create the directory, be sure you have root (or similar) permissions, and issue the following commands:
   
   % mkdir /usr/local/itt (to create)
% chmod a+rx /usr/local/itt (to give access)
2. Select the appropriate download link for your UNIX platform. Click on the link to download ENVI 4.4. The installation file is a compressed archive; save it in the directory in which you are installing ENVI (/usr/local/itt by default).
3. Unpack the archive. First uncompress the file by entering:
   
   % gunzip envi_platform.tar.gz
   
   then untar the file:
   
   % tar xf envi_platform.tar where platform is the platform name for your platform.
4. Now execute the installation program by entering the command:
   
   % ./install
   
   After the ENVI installation has been verified, you will be prompted to execute the install command. Enter y to continue the installation.
   
   Read the license agreement. If you accept, enter y to continue with the installation. Follow the on screen instructions to install and set up ENVI product environments and symbolic links.
5. If your platform supports ION Java, you will be prompted to specify the directory in which your web server looks for Java files. Specify the full path to the directory where Java files are located and press Enter. If you will not be using ION Java, press Enter without specifying a path.
6. If your platform supports ION Script, you will be prompted to specify the directory in which your web server looks for CGI executable files. Specify the full path to the directory where CGI executable files are located and press Enter. If you will not be using ION Script, press Enter without specifying a path.
7. If your platform supports ION Script, you will be prompted to specify fully-qualified domain name and path to the CGI executables directory for your web server. Specify the domain name and path and press Enter. If you will not be using ION Script, press Enter without specifying a domain or path.
8. If your platform supports DICOM Network Services, you will be asked if you want the network services to start automatically at boot time. If you will not be using DICOM Network Services, enter n.
9. After installation, you will need to license ENVI. Refer to the Installation and Licensing Guide (PDF) for details.
10. Your installation is now complete.
