Linking on Intel(R) 64 Architecture Systems

The following examples illustrate linking that uses Intel(R) compilers.

Most examples use the .f Fortran source file. C/C++ users should instead specify a .cpp (C++) or .c (C) file and replace ifort with icx.

In these examples,
MKLPATH=$MKLROOT/lib
/intel64_lin,
MKLINCLUDE=$MKLROOT/include
.

NOTE:

If you successfully completed the Scripts to Set Environment Variables Setting Environment Variables step of the Getting Started process, you can omit -I$MKLINCLUDE in all the examples and omit -L$MKLPATH in the examples for dynamic linking.

  • Static linking of myprog.f and OpenMP* threadedIntel® oneAPI Math Kernel Library (oneMKL) supporting the LP64 interface:

    ifort myprog.f -L$MKLPATH -I$MKLINCLUDE
    -Wl,--start-group $MKLPATH/libmkl_intel_lp64.a $MKLPATH/libmkl_intel_thread.a
    $MKLPATH/libmkl_core.a -Wl,--end-group -liomp5 -lpthread -lm

  • Dynamic linking of myprog.f and OpenMP* threadedIntel® oneAPI Math Kernel Library (oneMKL) supporting the LP64 interface:

    ifort myprog.f -L$MKLPATH -I$MKLINCLUDE
    -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core
    -liomp5 -lpthread -lm

  • Static linking of myprog.f and sequential version of Intel® oneAPI Math Kernel Library (oneMKL) supporting the LP64 interface:

    ifort myprog.f -L$MKLPATH -I$MKLINCLUDE
    -Wl,--start-group $MKLPATH/libmkl_intel_lp64.a $MKLPATH/libmkl_sequential.a
    $MKLPATH/libmkl_core.a -Wl,--end-group -lpthread -lm

  • Dynamic linking of myprog.f and sequential version of Intel® oneAPI Math Kernel Library (oneMKL) supporting the LP64 interface:

    ifort myprog.f -L$MKLPATH -I$MKLINCLUDE
    -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -lpthread -lm

  • Static linking of myprog.f and OpenMP* threadedIntel® oneAPI Math Kernel Library (oneMKL) supporting the ILP64 interface:

    ifort myprog.f -L$MKLPATH -I$MKLINCLUDE
    -Wl,--start-group $MKLPATH/libmkl_intel_ilp64.a $MKLPATH/libmkl_intel_thread.a
    $MKLPATH/libmkl_core.a -Wl,--end-group -liomp5 -lpthread -lm

  • Dynamic linking of myprog.f and OpenMP* threadedIntel® oneAPI Math Kernel Library (oneMKL) supporting the ILP64 interface:

    ifort myprog.f -L$MKLPATH -I$MKLINCLUDE
    -lmkl_intel_ilp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread -lm

  • Dynamic linking of user code myprog.f and OpenMP* threadedor sequential Intel® oneAPI Math Kernel Library (oneMKL)(Call appropriate functions or set environment variables to choose threaded or sequential mode and to set the interface):

    ifort myprog.f -lmkl_rt

  • Static linking of myprog.f, Fortran BLAS and 95 LAPACK interfaces, and OpenMP* threadedIntel® oneAPI Math Kernel Library (oneMKL) supporting the LP64 interface:

    ifort myprog.f -L$MKLPATH -I$MKLINCLUDE -I$MKLINCLUDE/intel64/lp64
    -lmkl_lapack95_lp64 -Wl,--start-group $MKLPATH/libmkl_intel_lp64.a $MKLPATH/libmkl_intel_thread.a
    $MKLPATH/libmkl_core.a -Wl,--end-group -liomp5 -lpthread -lm

  • Static linking of myprog.c and Intel® oneAPI Math Kernel Library (oneMKL) threaded with Intel® Threading Building Blocks (Intel® TBB), provided that the TBBROOT environment variable is defined:

    icx myprog.c -I$MKLINCLUDE -Wl,--start-group $MKLPATH/libmkl_intel_lp64.a $MKLPATH/libmkl_tbb_thread.a $MKLPATH/libmkl_core.a -Wl,--end-group -L$TBBROOT/lib/intel64/gcc.4.8 -ltbb -lstdc++ -lpthread -lm

  • Dynamic linking of myprog.c and Intel® oneAPI Math Kernel Library (oneMKL) threaded with Intel® TBB, provided that the LD_LIBRARY_PATH environment variable contains the path to Intel® TBB library:

    icx myprog.c -I$MKLINCLUDE -L$MKLPATH -lmkl_intel_lp64 -lmkl_tbb_thread -lmkl_core -lstdc++ -lpthread -lm
