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 is installed in the <mkl_directory>/bin/<arch> directory, and supports the modes described in the following table.

Intel 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 [Intel oneMKL Link Tool options]
		Get compilation options	mkl_link_tool -opts [Intel oneMKL Link Tool options]
		Get environment variables for application executable	mkl_link_tool -env [Intel 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), dpcpp 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
