netcdf-fortran problem (libnetcdfd.so) problem

[Parag0206]

• I am using netcdf-fortran@4.6.0 with gcc@9.1.0(netcdf-c, cxx are installed)
• CentOs 7 OS
• I am getting the following error while trying to compile an ocean model(MOM6). This error happens after makefile is run

  collect2: error: ld returned 1 exit status

  The libnetcdff.so file is causing a problem. Has anyone any idea regarding this error
