For PETSc 3.15.3, if I don't include mat/impls/aij/mpi/mumps/mumps.c, I have no compiling error. But I need it for using MUMPS. It is a compiling error rather than linking error.

My process only works for PTESc 3.11.3, not 3.15.3 and that's why I started this email thread.

If we go back to the original compiling error,

I don't understand what PETSC_PKG_MUMPS_VERSION_GE(5,3,0) is doing.

I believe I am using MUMPS since I have done following
(1) defined  -DPETSC_HAVE_MUMPS, 
(2) compiles and links mat/impls/aij/mpi/mumps/mumps.c
(3) link my pre-compiled MUMPS, and 
(4) specifies following PETSc options
       checkError(EPSGetST(eps, &st));
        checkError(STSetType(st, STSINVERT));
        //if(useShellMatrix) checkError(STSetMatMode(st, ST_MATMODE_SHELL));
        checkError(STGetKSP(st, &ksp));
        checkError(KSPSetOperators(ksp, A, A));
        checkError(KSPSetType(ksp, KSPPREONLY));
        checkError(KSPGetPC(ksp, &pc));
        checkError(MatSetOption(A, MAT_SPD, PETSC_TRUE));
        checkError(PCSetType(pc, PCCHOLESKY));
        checkError(PCFactorSetMatSolverType(pc, MATSOLVERMUMPS));
        checkError(PCFactorSetUpMatSolverType(pc));
        checkError(PetscOptionsSetValue(NULL, "-mat_mumps_icntl_13","1"));

Another evidence I am using MUMPS is that If I skip (1)-(3) above, I got the PETSc error saying that MUMPS is required.

mumps is a fortran package - so best to specify fc. Any specific reason for needing to force '--with-fc=0'?

The attached configure.log is not using mumps.
