Intel oneApi Toolkits
*********************
#. Download `Intel oneAPI Base Toolkit
<https://software.intel.com/content/www/us/en/develop/tools/oneapi/all-toolkits.html>`_
#. Assuming the toolkit is installed in ``/opt/intel/oneApi``, set environment
using::
export ONEAPI_TOOLCHAIN_PATH=/opt/intel/oneapi
source $ONEAPI_TOOLCHAIN_PATH/compiler/latest/env/vars.sh
To setup the complete oneApi environment, use::
source /opt/intel/oneapi/setvars.sh
The above will also change the python environment to the one used by the
toolchain and might conflict with what Zephyr uses.
#. Set :envvar:`ZEPHYR_TOOLCHAIN_VARIANT` to ``oneApi``.
