Intel® Fortran Compiler 9.0 for Linux*
Installation Guide

Contents

Introduction

This document explains how to install and configure for use the Intel® Fortran Compiler 9.0 for Linux* product. Installation is a multi-step process. Please read this document in its entirety before beginning and follow the steps in sequence. For information about the product contents, including new and changed features, please refer to the separate Release Notes.

If you have a previous (lower numbered) version of the Intel Fortran Compiler for Linux installed, you do not need to uninstall it before installing this version. If you choose to uninstall the older version, you may do so before or after installing this version. If you have version 9.0 installed, you can choose to replace the existing install or install to an alternate location.

System Requirements

Supported Host and Target Combinations

The following list describes the supported combinations of compilation host (system on which you build the application) and application target (system on which the application runs).

IA-32 Host
Supported targets: IA-32 and Intel® EM64T
Intel® EM64T Host
Supported targets: IA-32 and Intel® EM64T
Intel® Itanium® Host
Supported target: Intel® Itanium®

Note: Development for a target different from the host may require optional library components to be installed from your Linux Distribution.

Requirements to develop IA-32 applications

Requirements to Develop Applications for Systems with Intel EM64T or AMD Opteron Processors

Note: The requirement for the 32-bit (IA-32) libraries is due to the compiler and other tools being 32-bit applications that dynamically link to these libraries. If these libraries are not installed, the following error may be displayed when the compiler is invoked:

error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

The error message is confusing as it does not indicate that the IA-32 version of libstdc++.so.5 is required. To avoid this problem, be sure that the 32-bit (IA-32) versions of these libraries are installed. Most, but not all, Linux distributions for Intel EM64T will install these by default.

Requirements to Develop Itanium-based Applications

We recommend using binutils 2.14 or later, especially if using shared libraries as there are known issues with binutils 2.11.

We are unable to install on the unsupported configuration of Red Hat Enterprise Linux 4 beta systems without 32-bit support in the kernel. If you encounter this limitation please contact Intel® Premier Support for a workaround.

Notes:

Obtaining the Compiler and Tools

Before installing the compiler and tools, you should check the File Downloads section of Intel® Premier Support to see if a newer version or update is available. The version on CD or as listed in your electronic download license letter may not be the most current. In order to download and install a compiler from Intel Premier Support, you will first have to register for support as described below in the topic Obtaining Technical Support.

Installing the Compiler and Tools

If you encounter difficulty with the initial installation or registration process, please visit https://registrationcenter.intel.com/support to request help from Intel.

Perform the following steps to install the compiler.

  1. Unpack the compiler package in a directory to which you have write access.
    > tar -xvf l_fc_p_9.0.xxx.tar
    or
    > tar -zxvf l_fc_p_9.0.xxx.tar.gz
  2. Run the installation script
    Execute the install script in the directory where the tar file was extracted.
    > cd l_fc_p_9.0.xxx
    > ./install.sh
  3. If you are not logged in as root, you will be asked if you want to install as root, install as root using sudo, or to install without root privileges. Installing as root (using sudo if you have that privilege) is recommended, as that will update the system RPM database. Select root, sudo or ignore - the last says to install as not root. Use the not-root install if you want to install to a private area.
  4. The install script will display a series of options. Numbered options (e.g. 1, 2, 3) are used to install specific components or tools. There may be some suboptions (e.g. 1a, 1b, etc.) which can be used to obtain additional information before installing. Type 1 and press enter to begin the compiler installation.
  5. You will then be prompted to enter your Intel Fortran Compiler for Linux serial number. The serial number was provided to you when you purchased the product, either in an e-mail from the reseller or on a sticker attached to the CD-ROM package. You may also choose to enter a path to an existing license file. Make your selection and then follow the prompts.
  6. The install script then does some prerequisite checking and displays which Intel software development tools are installed, if any, and then offers a choice of a Typical Install or a Custom Install. Selection of a Typical Install is recommended - type 1 and press enter.
  7. Press enter again to display the license agreement. After the license agreement is displayed, you are prompted to accept or reject the license. If you accept the license, type accept and press enter. If you reject the license, type reject and press enter to end the install.
  8. The install will then continue - you may be prompted to accept further license agreements, specify install paths or to press enter to proceed through install steps.
  9. At the end of the installation, you will be prompted to register for Intel® Premier Support. Registration gives you full access to Intel Premier Support for the length of your support term (typically one year for licenses purchased with support), including all updates and new versions. Without registering, you will be unable to install or use product updates. Enter your e-mail address, when prompted, to register. (If you already have an Intel Premier Support account, enter its registered e-mail address.) You will then receive an e-mail with registration information including an initial password. If you do not wish to register, or if you have already registered, press x and press enter to exit.
  10. After registration, the install script exits.

Installation Warning for RPM 4.0.2 and RPM 4.1

RPM 4.0.2 cannot install to a non-default directory. This has been resolved in RPM 4.0.3. RPM 4.1 cannot install to a non-default directory. This has been resolved in RPM 4.11 to 4.2.

Installing the Intel License Server

If you have a floating, counted or node-locked license, the license must be installed in conjunction with the FLEXlm* license server for Intel software (Intel License Server), which is available for many popular platforms. The server may be installed on any supported platform accessible on your local network. The compiler CD contains license servers for several Linux distributions. If you do not have the CD, or need a license server for an additional platform, you can find all available license servers in the File Downloads section of your Intel® Premier Support account - select product Intel SW Dev Tools License Servers to find the server for your platform.

Installing the Intel License Server on SGI* Altix* Systems Running SGI ProPack* 3

If you will be installing the Intel License Server on an SGI* Altix* system running SGI ProPack* 3, please follow these alternate instructions to ensure correct operation in the partitioned cluster environment:

Setting Up the Compiler Environment

The programs in the Intel Fortran Compiler 9.0 for Linux product rely on the environment variables PATH and LD_LIBRARY_PATH. The installation script (install.sh) creates compiler environment script files (ifortvars.sh/idbvars.sh) that set these variables. It is strongly recommended that you add those script files into your login script (.login file). Once the variables are set in the ".login" file there is no need to run the script files for each session.

source the script to setup the compiler environment:

The installation program also creates compiler configuration files named <install-dir>/bin/ifort.cfg that contain common settings for all compilations. You can edit these files to add additional default options. Note, if you install a compiler update package, you need to save the configuration file, if you have modified it, to another filename so that the installation doesn't overwrite your modified file.

If you have not already done so, please register for support after you install this product. See Obtaining Technical Support below for registration instructions.

Uninstalling the Compiler and Tools

Please follow the steps below to uninstall the Intel Compiler and Debugger.

  1. If you installed as root, you will need to log in as root
  2. To uninstall the compiler:
    <compiler-install-dir>/bin/uninstall.sh
    or if you've installed the compiler to the default directory, use
    /opt/intel/fc/9.0/bin/uninstall.sh or
    /opt/intel/fce/9.0/bin/uninstall.sh on Intel EM64T-based systems
  3. To uninstall the debugger:
    <debugger-install-dir>/bin/uninstall.sh
    or if you've installed the debugger to the default directory, use
    /opt/intel/idb/9.0/bin/uninstall.sh or
    /opt/intel/idbe/9.0/bin/uninstall.sh on Intel EM64T-based systems
