Bram,
Sorry for the delay. I've attached a new src/vec/vec/impls/mpi/pmap.c
just drop it in and do make lib shared in that directory. Also add the
following lines to include/private/vecimpl.h
EXTERN PetscErrorCode PETSCVEC_DLLEXPORT
PetscMapSetLocalSize(PetscMap*,PetscInt);
EXTERN PetscErrorCode PETSCVEC_DLLEXPORT
PetscMapGetLocalSize(PetscMap*,PetscInt *);
PetscPolymorphicFunction(PetscMapGetLocalSize,(PetscMap m),(m,s),PetscInt,s)
EXTERN PetscErrorCode PETSCVEC_DLLEXPORT PetscMapSetSize(PetscMap*,PetscInt);
EXTERN PetscErrorCode PETSCVEC_DLLEXPORT PetscMapGetSize(PetscMap*,PetscInt *);
PetscPolymorphicFunction(PetscMapGetSize,(PetscMap m),(m,s),PetscInt,s)
EXTERN PetscErrorCode PETSCVEC_DLLEXPORT
PetscMapGetLocalRange(PetscMap*,PetscInt *,PetscInt *);
EXTERN PetscErrorCode PETSCVEC_DLLEXPORT
PetscMapGetGlobalRange(PetscMap*,PetscInt *[]);
EXTERN PetscErrorCode PETSCVEC_DLLEXPORT
PetscMapSetSizeBlockSize(PetscMap*,PetscInt);
EXTERN PetscErrorCode PETSCVEC_DLLEXPORT
PetscMapGetSizeBlockSize(PetscMap*,PetscInt *);
The manual pages are in the pmap.c file. Please let us know if you have
any difficulties.

Hi,
in PETSc 2.3.1, PetscMap is not longer a public object. However, my code
depends quite a lot on this object and its functions like
PetscMapGetGlobalRange. So far I have not managed to port
my code to version 2.3.1. Is there another way to obtain functionality
of the PetscMap object?
Best regards,
Bram Metsch

PetscMapInitialize - given a map where you have set either the global or
local
size sets up the map so that it may be used.
Collective on MPI_Comm
Input Parameters:
+comm - the MPI communicator
-map - pointer to the map
Level: intermediate
Notes:
You must call PetscMapSetBlockSize() and either PetscMapSetSize() or
PetscMapSetLocalSize()
before calling this routine.
Unlike regular PETSc objects you work with a pointer to the object
instead of
the object directly.
