[petsc-users] Building Sieve examples

[Stefan Kurzbach]

Hello everybody,

when looking for examples using Sieve for unstructured meshes I found 
these 3 (in 
http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-current/docs/manualpages/Mesh/MeshCreate.html):

src/ksp/ksp/examples/tutorials/ex33.c.html 
<http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-current/src/ksp/ksp/examples/tutorials/ex33.c.html>
src/ksp/ksp/examples/tutorials/ex35.c.html 
<http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-current/src/ksp/ksp/examples/tutorials/ex35.c.html>
src/ksp/ksp/examples/tutorials/ex37.c.html 
<http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-current/src/ksp/ksp/examples/tutorials/ex37.c.html>

I have built PETSc configuring --with-sieve successfully. Unfortunately 
trying to build these examples ("make ex35") fails with error messages 
similar to the one below (and many more):

/home/software/mpi/intel/openmpi-1.2.4/bin/mpicxx -o ex35.o -c -O

ex35.c(21): error: name followed by "::" must be a class or namespace name
   PetscErrorCode MeshView_Sieve_Newer(ALE::Obj<ALE::Two::Mesh>, 
PetscViewer);

Without digging deeper into the code,  are these examples still working 
with the current version of PETSc? What am I missing or where can I find 
up-to-date information?

Thanks a lot,
Stefan
