Setting Environment Variables

When the installation of Intel MKL for Windows* is complete, set the PATH, LIB, and INCLUDE environment variables in the command shell using the mklvars.bat script in the bin subdirectory of the Intel MKL installation directory.

The script accepts the parameters, explained in the following table:

For example:

  • The command
    mklvars intel64
    sets the environment for Intel MKL to use the Intel 64 architecture.

  • The command
    mklvars intel64 mod ilp64
    sets the environment for Intel MKL to use the Intel 64 architecture, ILP64 programming interface, and Fortran modules.

  • The command
    mklvars intel64 mod
    sets the environment for Intel MKL to use the Intel 64 architecture, LP64 interface, and Fortran modules.

Note

Supply the parameter specifying the architecture first, if it is needed. Values of the other two parameters can be listed in any order.
