oneAPI source scripts for Linux, macOS and Windows

Readme.md

tiny scripts to load oneAPI environment

For PowerShell and Unix-like shells, here are example scripts to load and use Intel oneAPI on Windows and Linux.

Optionally, the version can be specified.

• Linux: source oneapi.sh or source oneapi.sh 2025.3
• Windows . .\oneapi.sh or . .\oneapi.sh 2025.3

Windows example output

If the lines ending in "vars.bat" below aren't seen, probably oneAPI is not correctly installed. Ensure that before installing oneAPI that Visual Studio Desktop Development with C++ workload was installed. If needed, do that, then "Repair" the oneAPI install.
