Setting Environment Variables

When the installation of Intel MKL for Linux* OS is complete, set the INCLUDE, MKLROOT, LD_LIBRARY_PATH, MIC_LD_LIBRARY_PATH, MANPATH, LIBRARY_PATH, CPATH, and NLSPATH environment variables in the command shell using one of the script files in the bin subdirectory of the Intel MKL installation directory. The environment variable MIC_LD_LIBRARY_PATH specifies locations of shared objects for Intel® MIC Architecture.

Choose the script corresponding to your system architecture and command shell as explained in the following table:

Architecture	Shell	Script File
IA-32	C	ia32/mklvars_ia32.csh
IA-32	Bash and Bourne (sh)	ia32/mklvars_ia32.sh
Intel® 64	C	intel64/mklvars_intel64.csh
Intel® 64	Bash and Bourne (sh)	intel64/mklvars_intel64.sh
IA-32 and Intel® 64	C	mklvars.csh
IA-32 and Intel® 64	Bash and Bourne (sh)	mklvars.sh

Running the Scripts

The parameters of the scripts specify the following:

Architecture.
Use of Intel MKL Fortran modules precompiled with the Intel® Fortran compiler. Supply this parameter only if you are using this compiler.
Programming interface (LP64 or ILP64).

Usage and values of these parameters depend on the name of the script (regardless of the extension). The following table lists values of the script parameters.

Script	Architecture (required, when applicable)	Use of Fortran Modules (optional)	Interface (optional)
`mklvars_ia32`	n/a^†	`mod`	n/a
`mklvars_intel64`	n/a	`mod`	`lp64`, default `ilp64`
`mklvars`	`ia32` `intel64`	`mod`	`lp64`, default `ilp64`

^† Not applicable.

For example:

The command
mklvars.sh ia32
sets the environment for Intel MKL to use the IA-32 architecture.
The command
mklvars.sh intel64 mod ilp64
sets the environment for Intel MKL to use the Intel® 64 architecture, ILP64 programming interface, and Fortran modules.
The command
mklvars.sh 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.
