This document provides details about hardware, operating system, and software prerequisites for the Intel® Fortran Compilers: Intel® Fortran Compiler (ifx) and Intel® Fortran Compiler Classic (ifort). There is also information about the development environment options.

 Please see the Intel® Fortran Compiler Release Notes for additional information.

Directory Layout Change

The directory layout is improved across all products to streamline installation and setup.

The Unified Directory Layout is implemented in 2024.0. If you have multiple toolkit versions installed, the Unified layout ensures that your development environment contains the correct component versions for each installed version of the toolkit.

The directory layout used before 2024.0, the Component Directory Layout, is still supported on new and existing installations.

For detailed information about the Unified layout, including how to initialize the environment and advantages with the Unified layout, refer to Use the setvars and oneapi-vars Scripts with Linux and Use the setvars and oneapi-vars Scripts with Windows.

Known Issues

  • The environment start up scripts have been migrated to POSIX compliant scripts. For non-POSIX shells, such as csh, there is a workaround for command-line usage for the Component Directory Layout:

    % bash -c 'source /opt/intel/oneapi/setvars.sh ; exec csh'

    For the Unified Directory Layout use

    % bash -c 'source <install-dir>/<toolkit-version>/oneapi-vars.sh ; exec csh'

KNOWN ISSUES

  • Intel® oneAPI Toolkits 2022.1.3 and earlier and Intel® Parallel Studio XE (any version) do not support Microsoft Visual Studio 2022. On systems with Microsoft Visual Studio 2022 installed, Intel® oneAPI and Intel® Parallel Studio XE installers may fail during installation, upgrade, modification, or uninstallation. Refer to this article for more information.
  • For the oneAPI 2024.2 release, the Microsoft Visual Studio validated versions are the same as for oneAPI 2024.1:
    • up to Visual Studio 2022   version 17.9.2
    • up to Visual Studio 2019   version 16.11.34 

See Intel® Compilers Compatibility with Microsoft Visual Studio* and Xcode*. Please be aware of this when updating Visual Studio.

macOS*

NOTE Intel oneAPI HPC Toolkit for macOS on x86 is discontinued in the 2024.0 release.  This includes Intel® Fortran Compiler Classic (ifort). Several Intel-led open-source developer tool projects will continue supporting macOS on Apple Silicon including Intel® oneAPI Threading Building Blocks (oneTBB) and Intel® Implicit SPMD Program Compiler and we welcome the opportunity to work with contributors to expand support to additional tools in the future.
