ld error on Mac Monterey 1.2 gcc version 11.2.0

[Zhang Mian]

Hi
   When I tried old gfortran7, the below works:

     gfortran-7  dgesvd-ex.f -o DGESVD.out  -L/usr/local/opt/lapack/lib    
-llapack     -lblas

  But gfortran 11 failed:
     
     gfortran  dgesvd-ex.f -o DGESVD.out  -L/usr/local/opt/lapack/lib    
-llapack     -lblas
     ld: library not found for -lSystem
     collect2: error: ld returned 1 exit status

  on iMac Pro Monterey 1.2, gcc version 11.2.0(Homebrew GCC 11.2.0_3) .
  Any idea? Thanks~
