Known Issues and Workarounds

  1. Known Issue: 

    If you installed Intel compilers as part of the oneAPI 2023.2 release of the Intel® oneAPI Base Toolkit, the Intel® oneAPI HPC Toolkit, the Intel® oneAPI IoT Toolkit, or from the oneAPI Standalone Component page, please install the appropriate patch for your environment. 

    Two patches are now available, one for each of the Intel C++ and Fortran compilers, that were published as part of oneAPI 2023.2:

    * Intel® oneAPI DPC+/C+ Compiler and Intel® C++ Compiler Classic
    * Intel® Fortran Compiler Classic and Intel® Fortran Compiler

    The patch version is 2023.2.1.

    These patches apply only to Linux* and Windows*.

    These patches resolve the issue of missing Environment Modules utility modulefiles and other issues.

    The patches are available on the Intel® Registration Center, other distribution channels, like APT, YUM, and the standalone component page.

  2. Known Issue: When using Intel® oneAPI DPC++/C++ Compiler on a Linux machine, users may run into an issue if the highest version of GNU gcc detected doesn't have the equivalent g++ package installed. More details on the error and workarounds can be found here.
  3. Known Issue: When a user installs oneAPI BaseKit 2022.1.3 over oneAPI BaseKit 2022.1.2 with VS2022 version 17.1.x installed, the installer updates and does not crash. But some components of BaseKit 2022.1.2 are not removed during the update process.
  4. Workaround: 

    Deinstall all Visual Studio instances.
    Deinstall oneAPI BaseKit 2022.1.2.
    Reinstall Visual Studio 2022 version 17.1.x.
    Install BaseKit 2022.1.3.

  5. On Microsoft* Windows*, the installation of Intel oneAPI Toolkits versions 2022.1 and 2022.1.2 and standalone components will fail using Microsoft* Visual Studio* 2022 version 17.1.x. There are 2 possible workarounds, prior to installing an Intel oneAPI toolkit or component:
    • Uninstall Visual Studio 2022 version 17.1.x and install the older version 17.0.6 from here Visual Studio 2022 Release History | Microsoft Docs.
    • Replace Microsoft.VisualStudio.Setup.Configuration.Native.dll with same dll from a Visual Studi0 2022 17.0.x release. For example, from version 17.0.6 https://docs.microsoft.com/en-us/visualstudio/releases/2022/release-history
    • We are striving to provide a new release in the weeks ahead to address this installation issue.
  6. System OS Known Issues
    1. ​When installing Rocky Linux using the YUM repository or the binary package, the installer prints an unsupported OS warning message.  That can be safely ignored for this release.
    2. For best support users of Ubuntu 18.0.4 LTS whose applications offload to Intel GPUs are encourage to upgrade to Ubuntu 20.4 LTS.
  7. For customers who installed Intel® oneAPI Base Toolkit 2022.1.2 and applied the workaround described in Known Issues and Limitations section of Release Notes for that release:
    1. Install Intel® oneAPI IoT Toolkit 2022.1.2 and remove previously applied workaround that was documented in the Intel oneAPI Base Toolkit Release Notes.

See the Intel® oneAPI Base Toolkit Release Notes for additional details and issues common to multiple toolkits.
If you have any questions and have paid for Priority Support, create a case at Online Service Center. Otherwise, post a message on the Intel oneAPI Registration Forum.
