error LNK2001: unresolved external symbol


Hi, I am using the fortran90 with mpi. I followed the steps on this website to link the mpi with visual studio 2017. But it didn't work. It shows error LNK2001 to every MPI commands. Like error LNK2001: unresolved external symbol _MPI_ALLREDUCE; error LNK2001: unresolved external symbol _MPI_BARRIER  .etc. I can not even compile the test.f90 code.

These attached pictures show my configuration. Is there any problem? Have someone met the same problem before? How can I solve it?

Thanks a lot!
