Redhat Linux Version 8 Commands to Install Intel Fortran 90/95 Compiler
Version 8.0.xxx for Linux.

by Skip Knoble and Jason Holmes, Penn State, 16 December 2003

Files we put on our Intel Fortran CD which were downloaded from:
http://www.intel.com/software/products/compilers/downloads/forlin.htm
The license file was obtained via email by registering the product.

Note: Note that Intel Fortran 7.1 for Linux will not work properly
      under Red Hat Linux 9.0. Intel Fortran 8.0 will.
      http://www.intel.com/software/products/compilers/beta/welcome.htm
      To get Fortran 8.0, you need to register for Priemere Support;
      once logged in to Priemere Support you can download Intel Fortran
      for Linux Version 8.0.xxx.

0) You need to get a licence and serial number via:
   http://developer.intel.com/software/products/compilers/flin/noncom.htm
   If you don't have this information, the install will fail.
1) Login as the Root user
2) Open a Terminal Window (click RedHat/System Tools/Terminal
3) Change directories to your regular user directory;
   e.g., cd /home/psuaset
4) Make a temporary directory to contain all the files on CD
   mkdir temp
5) Change to this temporary directory: cd temp
6) Mount the CD-ROM drive:  mount /dev/cdrom
7) Copy the files from CD to /home/psuaset/temp
   cp /mnt/cdrom/*.* /home/psuaset/temp
8) Unmount the CD: umount /dev/cdrom
   Remove the CD from the CD-ROM drive.
9) Set the Intel License environment variable by issuing the command:
   export INTEL_LICENSE_FILE="opt/intel_fc_80/licenses"
   You can verify that this was set by issuing the command:
   export
10 Create the license file subdirectory:
   cd /
   mkdir opt
   cd opt
   mkdir intel
   cd intel
   mkdir licenses
   cd /home/psuaset/temp
11) Copy the LICENSE file to it's location:
    cp *.lic /opt/intel/licenses/
12) Extract the intall file l_fc_p_8.0.034.tar or tar.gz
    tar -xvf l_fc_p_8.0.xxx.tar
                 or
    tar -zxvf l_fc_p_8.0.xxx.tar.gz
    where xxx is the current level (e.g., 034).
    This should extract to directory: /home/psuaset/temp/intel_fc_80
13) Install the compiler(1) issue the command:
    cd /home/psuaset/temp/intel_fc_80
    ./install.sh
    Reply to any prompts, typically by pressing enter.
    You might need to specify the license file; if so specify it as:
    /opt/intel_fc_80/licenses/l_for_nnnnnnnn.lic where nnnnnnnn is
    part of the filename of your license file.

    Then at the second prompt for 1 Compiler and 2) Debuggger
    enter x to exit the install. Prior to entering X after the
    installs, you should see 2 messages: Install successful
    This should install ifort to: /opt/intel_fc_80 and the debugger
    to: /opt/intel_idb_73 .
14) Erase all the install files in /home/psuaset/temp
    cd /home/psuaset
    rm -f -r temp
15) Logout from Root user and log in as a regular user.
16) Login as a non-root user; e.g. psuaset
17) Open a Terminal Window (click RedHat/System Tools/Terminal
18) Issue the command: cd /home/psuaset
19) Use the text editor (RedHat/Accessories/Text Editor) to edit the file:
    /home/psuaset/.bash_profile
    and after the last line of this file add the line:
    . /opt/intel_fc_80/bin/ifortvars.sh
    (Note the leading period followed by space)
    Then SAVE this file under the same name, .bash_profile .
    After next login, this will set the Intel Fortran Environment variables
    so the compiler can be found and run from any terminal prompt.
20) Logout
21) Login as a non-root user again; e.g., psuaset
22) Create a Fortran program subdirectory by issuing the commands:
    cd /home/psuaset
    mkdir fort
    cd fort
23) Create a simple Fortran Program using the Text Editor (RedHat/Accessories/
    Text Editor) to create and SAVEAS the file /home/psuaset/fort/hello.f90
Program Hello
 print *, "Hello World!"
End Program Hello
24) Run the program by issuing the commands:
    ifort hello.f90 -o hello
    ./hello
    This should display: Hello World!
    Note: For extensions .f, for .f77 the format defaults to Fixed form.
    Free form can be specified using option:  -FR (case sensitive)
25) Issue the command: ifort -help > iforthelp.txt
    You can edit this file to see various compiler/preprocessor/linker options.
    Also see the files in /opt/intel_fc_80/docs (various manuals in PDF
    format, and some text files copied from the Intel Fortran Web pages.
