'undefined reference to...' Error when compling in linux

[nvh10]

My program is just simple, calculate inverse matrix by using mkl libraries. 

I used the following ifort command to compile:

ifort -c -qopenmp -I$/openmp/intel/oneapi/mkl/2022.1.0/include/intel64/ilb64-m64 -DMKL_ILP64 -i8  -I"$/opt/intel/oneapi/mkl/2022.1.0/include" -fpp -nologo -O3 -Os -parallel -heap-arrays[0] -qopenmp testmkl.f90
ifort -o testmkl testmkl.o

The following error appears:

testmkl.o: In function `inversematrixd_': testmkl.f90:(.text+0x97):

undefined reference to `dgetrf_' testmkl.f90:(.text+0xbc):

undefined reference to `dgetri_' testmkl.o: In function `MAIN__': testmkl.f90:(.text+0x12f): undefined reference to `__kmpc_begin' testmkl.f90:(.text+0x149):

undefined reference to `__kmpc_for_static_init_8' testmkl.f90:(.text+0x2b5):

undefined reference to `__kmpc_for_static_fini'

Please help me! Sorry, I am just a beginner so please instruct me step by step!

Thank you very much!
