Linking on Intel(R) 64 Architecture Systems

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

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

Note

If you successfully completed the 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.

In these examples,
MKLPATH=$MKLROOT/lib/intel64,
MKLINCLUDE=$MKLROOT/include:

• Static linking of myprog.f and parallel Intel MKL 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
  

• Dynamic linking of myprog.f and parallel Intel MKL supporting the LP64 interface:

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

• Static linking of myprog.f and sequential version of Intel MKL 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
  

• Dynamic linking of myprog.f and sequential version of Intel MKL supporting the LP64 interface:

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

• Static linking of myprog.f and parallel Intel MKL 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
  

• Dynamic linking of myprog.f and parallel Intel MKL supporting the ILP64 interface:

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

• Dynamic linking of user code myprog.f and parallel or sequential Intel MKL (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 95 LAPACK interface, and parallel Intel MKL 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
  

• Static linking of myprog.f, Fortran 95 BLAS interface, and parallel Intel MKL supporting the LP64 interface:

  ifort myprog.f -L$MKLPATH -I$MKLINCLUDE -I$MKLINCLUDE/intel64/lp64
  -lmkl_blas95_lp64 -Wl,--start-group $MKLPATH/libmkl_intel_lp64.a $MKLPATH/libmkl_intel_thread.a
  $MKLPATH/libmkl_core.a -Wl,--end-group -liomp5 -lpthread
