In this example, the user tries to run setvars.sh twice. This behavior can be overridden by passing setvars.sh the -force flag. This is done to ensure that your environment variables do not become too long due to redundant path references, especially the $PATH environment variable.

Inspect the individual vars.sh scripts to determine which, if any, command line arguments they accept.īecause many of the individual env/vars.sh scripts make significant changes to PATH, CPATH, and other environment variables, the top-level setvars.sh script will not allow multiple invocations of itself in the same session. The most common extra arguments are ia32 and intel64, which are used by the Intel compilers and the IPP, MKL, and TBB libraries to specify the application target architecture. That is, if the setvars.sh script does not recognize an argument, it assumes the argument is meant for use by one or more component scripts and passes those extra arguments to every component vars.sh script that it calls. More details and examples are provided in Use a Config file for setvars.sh on Linux or macOS.Īny extra arguments passed on the setvars.sh command line that are not described in the setvars.sh help message will be passed to every called vars.sh script. For example, to limit environment setup to just the Intel® IPP library and the Intel® oneAPI Math Kernel Library (Intel® oneMKL), pass a config file that tells the setvars.sh script to only call the vars.sh environment scripts for those two oneAPI components. It also provides a way to initialize the environment for specific component versions. The -config=file argument provides the ability to limit environment initialization to a specific set of oneAPI components. The -config=file argument and the ability to include arguments that will be passed to the vars.sh scripts that are called by the setvars.sh script can be used to customize the environment setup. For example: source /opt/intel/oneapi/setvars.sh -help

The setvars.sh script supports several command-line arguments, which are displayed using the -help option.
