Installing the Intel® Visual Fortran Compiler 10.1 for GEMPACK

[Last updated: 27th April 2012]

Please print out and read this section before beginning the installation procedure. This procedure is for



Installation check list

For the installation you should have the following:

Your installation procedure will depend on your version of Windows and choice of Intel Fortran compiler. The installation steps given in the next section clearly indicate the appropriate choices for each combination.

Installation steps

The installation procedure we describe here is straight forward and varies only slightly from the defaults suggested by the Intel install program.

  1. Start the install by running the w_fc_p_10.1.xxx.exe install program.
  2. Click through the installation procedure accepting the default settings until you reach the "Setup Type" dialogue where the choice you are presented with is Complete or Custom. Select Custom and click Next.
  3. On the following "Choose Destination Location" dialogue click Next.
  4. For 32-bit installations complete step 4a, for 64-bit installations complete step 4b.
    1. 32-bit Installations. On the "Select Features" dialogue alter the default selections as follows. Expand the item "Intel(R) Visual Fortran Compiler" by clicking on the adjacent + symbol, and clear the box beside "Compile applications for Intel(R) 64". Also clear the box adjacent to "Intel(R) Debugger". Your selection should look like Figure 1. Go to step 5.

    2. 64-bit Installations. On the "Select Features" dialogue alter the default selections as follows. Expand the item "Intel(R) Visual Fortran Compiler" by clicking on the adjacent + symbol, and clear the box beside "Compile applications for IA-32". Also clear the box adjacent to "Intel(R) Debugger". Your selection should look like Figure 2. Go to step 5.

  5. Confirm your selections and click Next.
  6. At the "Ready to Install" dialogue, click Install.
  7. A sequence of dialogues now follows. You will need to accept the MSVSPPE licence agreement, click through the subsequent dialogues accepting the defaults. If the install program detects that your Windows installation does not already have "Microsoft .NET Framework 2.0" installed you will be prompted through the .NET installation. Several progress dialogues follow indicating that the Intel Fortran compiler components are being installed.<\li>
  8. Vista installations only. [Go on to point 9 if not using Vista.] If you are installing under Vista you will see during the installation step installing "Integrations in Microsoft Visual Studio" the warning message in Figure 3 below

    Vista known compatibility issues warning

    Click Run program and complete the installation. This issue will be taken care of by installing the two service packs that you have already downloaded in the subsequent steps.
  9. Eventually you will see "Installation Complete". Click Finish.
  10. Installation of the Visual Studio service pack is recommended for Windows XP and is compulsory for installations on later versions of Windows. To install this service pack, run the install program
    VS80sp1-KB926601-X86-ENU.exe
    which is your downloaded copy of Microsoft® Visual Studio® 2005 Team Suite Service Pack 1.
    The service pack is quite large and may take a few minutes to install.
  11. Installation of a second Visual Studio service pack is compulsory on post-XP versions of Windows. [Skip this step if you are installing on Windows XP.] To install this service pack, run the installation file
    VS80sp1-KB932232-X86-ENU.exe
    which is your downloaded copy of Visual Studio 2005 Service Pack 1 Update for Windows Vista.
  12. Complete the next section to edit the System Path variable.

Editing the System PATH environment variable

This section gives detailed instructions for editing the Windows system path variable. You must complete this section in order for Release 10 Source-code GEMPACK to work with Intel Visual Fortran 10.1.

Open the System Properties dialogue as follows:

Make sure that you edit the lower "System variables" panel, not the upper "User variables" panel.



The change you need to make to the Path variable value depends on which version of the compiler you have installed.

Click Ok to accept the changes, and Ok again to close the Environment Variables and System Properties dialogues.

"Hello World" test for Intel Fortran 10.1

You can test your installation of Intel Fortran as follows. Right click and choose "Save Link As" or "Save Target As" depending on your browser, to save the small program hello.for into a temporary folder, say C:\test. When compiled and executed this program will write "Hello World" to the terminal. Next, open a command prompt in the C:\test folder (containing hello.for). To test the installation, type the following commands.

C:\test>ifortvars
C:\test>ifort hello.for
C:\test>hello

The first command, ifortvars, sets up the environment for the compiler, and will not work if you have not correctly edited the system path as described above. The second command, ifort hello.for, compiles the executable program hello.exe. And the third command, hello, runs the hello.exe program which will write the words "Hello World" to the terminal. If you see "Hello World" then your compiler installation is working.

Other Comments

When Intel Visual Fortran 10.1 is installed by following the above procedure, either the 32-bit or 64-bit compiler is installed; you must select the same compiler during the GEMPACK installation. If you want to change the compiler that GEMPACK works with, you need to partially reinstall your Intel Fortran to include the other choice of compiler. Next, modify the system path variable to reflect your new choice of compiler. Then reinstall GEMPACK (Release 10.0-000 or later). Note that GEMPACK with IF64 (Intel Fortran 64-bit) will only work if you are using 64-bit Windows.
