5 Intel® Math Kernel Library User’s GuideSelecting Libraries to LinkBelow are several simple examples of link libraries for the layered pure and layered defaultlink models on 64-bit Linux* based on Intel® 64 architecture for different componentsusing Intel® compiler interface.• BLAS, FFT, VML, VSL components, static case:Layered default: libmkl_em64t.aLayered pure: libmkl_intel_lp64.a libmkl_intel_thread.a libmkl_core.a• BLAS, FFT, VML, VSL components, dynamic case:Layered default: libmkl.soLayered pure: libmkl_intel_lp64.so libmkl_intel_thread.so libmkl_core.so• LAPACK, static case:Layered default: libmkl_lapack.a libmkl_em64t.aLayered pure: libmkl_intel_lp64.a libmkl_intel_thread.a libmkl_core.a• LAPACK, dynamic case:Layered default:libmkl_lapack.so libmkl.soLayered pure: libmkl_intel_lp64.so libmkl_intel_thread.so libmkl_core.so• ScaLAPACK, static case:Layered default: libmkl_scalapack.a libmkl_blacs.a libmkl_lapack.alibmkl_em64t.aLayered pure: libmkl_intel_lp64.a libmkl_scalapack_core.alibmkl_blacs.a libmkl_intel_thread.a libmkl_core.a• PARDISO, static case:Layered default: libmkl_solver.a libmkl_lapack.a libmkl_em64t.aLayered pure, LP64: libmkl_solver_lp64.a libmkl_intel_lp64.alibmkl_intel_thread.a libmkl_core.aLayered pure, ILP64: libmkl_solver_ilp64.a libmkl_intel_ilp64.alibmkl_intel_thread.a libmkl_core.aWhen linking (see Link Command Syntax and Linking Examples), note that• The solver library currently does not comply with the layered model. So, it is notchanged internally with respect to the Intel MKL 9.x. However, to support LP64/ILP64interfaces, two libraries were introduced in the unified structure:libmkl_solver_lp64.a for the LP64 interface and libmkl_solver_ilp64.a for theILP64 interface. For backward link line compatibility libmkl_solver.a has become adummy library. There is still only static version of the solver library, as it was forprevious releases. To link with the solver library using the pure layered model, includethe library libmkl_solver_lp64.a or libmkl_solver_ilp64.a in the link line,depending upon the interface you need.5-6
Linking Your Application with Intel® Math Kernel Library 5• libmkl_lapack95.a and libmkl_blas95.a libraries contain LAPACK95 and BLAS95interfaces respectively. They are not included into the original distribution and shouldbe built before using the interface. (See “Fortran 90 Interfaces and Wrappers toLAPACK and BLAS” section in chapter 7 for details on building the libraries and“Compiler-dependent Functions and Fortran 90 Modules” section on why source code isdistributed in this case.)• To use the Intel MKL FFT, Trigonometric Transform, or Poisson, Laplace, and HelmholtzSolver routines, link in the math support Linux library by adding "-lm" to the link line.• In products for Linux, it is necessary to link the pthread library by adding-lpthread. The pthread library is native to Linux and libguide makes use of thislibrary to support multi-threading. Any time libguide is required, add -lpthread atthe end of your link line (link order is important).Linking ExamplesBelow are some specific examples of linking using the Intel® compilers on systems basedon Intel® 64 architecture. In these examples, and placeholders are replaced with user-defined environment variables $MKLPATH and$MKLINCLUDE, respectively.
