[petsc-users] Undefined reference in PETSc 3.13+ with old MPI version

[Barry Smith]

  Depending on the network you can remove the ./configure options --with-cc=mpicc --with-cxx=mpicxx --with-fc=mpif90  and use instead --with-cc=icc --with-cxx=icpc and--with-fc=ifort --download-openmpi

I have no problem to install PETSc up to version 3.12.5. However, if I try to use PETSc 3.13+, there are three undefined reference errors in MPI_Win_allocate, MPI_Win_attach and MPI_Win_create_dynamic. I know these three functions are available from OpenMPI 2.0+. Because the cluster is not in technical support anymore, there is no way I can install new OpenMPI version or do some update. Is it possible to disable these three functions in PETSc 3.13+ version?
