Using the Command-Line Link Tool

Use the command-line Link Tool provided by

Intel® oneAPI Math Kernel Library

to simplify building your application with

Intel® oneAPI Math Kernel Library

The tool not only provides the options, libraries, and environment variables to use, but also performs compilation and building of your application.

The tool

mkl_link_tool.exe

is installed in the

<mkl_directory>\bin

directory, and supports the modes described in the following table.

oneMKL Command-Line Link Tool Modes
Mode	Description	Usage	Example
Inquiry	The tool returns the compiler options, libraries, or environment variables necessary to build and execute the application.	Get Intel® oneAPI Math Kernel Library libraries	`mkl_link_tool -libs [oneMKL Link Tool options]`
		Get compilation options	`mkl_link_tool -opts [oneMKL Link Tool options]`
		Get environment variables for application executable	`mkl_link_tool -env [oneMKL Link Tool options]`
Compilation	The Intel® oneAPI Math Kernel Library Link Tool builds the application.	—	`mkl_link_tool [options] <compiler> [options2] file1 [file2 ...]` where: `options` represents any number of Link Tool options `compiler` represents the compiler name: ifort, icc (icpc, icl), cl, gcc (g++), gfortran, pgcc (pgcp), pgf77 (pgf90, pgf95, pgfortran), mpiic, mpiifort, mpic (mpic++), mpif77 (mpif90, mpif95) , icx -fsycl `options2` represents any number of compiler options
Interactive	Allows you to go through all possible Intel® oneAPI Math Kernel Library Link Tool supported options. The output provides libraries, options, or environment variables as in the inquiry mode, or a built application as in the compilation mode (depending on what you specify).	—	`mkl_link_tool -interactive`
