Math Kernel Library Developer Guide
The following examples illustrate linking that uses Intel® 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 icc.
In these examples,
MKLPATH=$MKLROOT/lib/intel64_lin,
MKLINCLUDE=$MKLROOT/include.
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 supporting the LP64 interface:

Static linking of myprog.c and Intel® oneAPI Math Kernel Library threaded with Intel® Threading Building Blocks (Intel® TBB), provided that the TBBROOT environment variable is defined:
icc 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 threaded with Intel® TBB, provided that the LD_LIBRARY_PATH environment variable contains the path to Intel® TBB library:
