Hello,
when trying to build against VTK I had to modify the libmesh-Makefiles
to make it work:
Index: m4/vtk.m4

I compiled VTK 5.4.2 from the sources and installed it into ~/opt/. For libmesh
I use the following configure-line:
> ./configure --enable-mpi --enable-shared --enable-exceptions
> --enable-unordered-containers \
> --enable-periodic --enable-ghosted --enable-second --enable-petsc
> --enable-slepc \
> --enable-laspack --enable-gzstreams --enable-bzip2 --enable-vtk
> --enable-tecplot \
> --enable-exodus --with-vtk-include=~/opt/include/vtk-5.4 \
> --with-vtk-lib=~/opt/lib/vtk-5.4
When trying to build against vtk 5.6 I get the following error:
> /usr/bin/ld: bin/grid2grid-opt: hidden symbol `vtkUnstructuredGrid::New()' in

As I have noticed this with libmesh 0.7.0.3 and 0.7.1, I am wondering, if there
is something wrong with the way I am building against vtk.
Additionally there is an issue within VTKIO when having a variable of a
MONOMIAL family
in a system. As I currently not need these variables in the output, I just skip
them:

vtkDoubleArray *data = vtkDoubleArray::New();
And finally I have some trouble using BoundaryInfo: When using
MeshTools::Generation::
the boundary sides are numbered zero-based, but when reading a mesh from a
ExodusII-file
the boundary sides are numbered starting at one. The ExodusII-file was created
using
cubit and sidesets. The smallest id which cubit allowes me to assign is 1.
So how do I get the boundary sides starting by zero from cubit into libmesh?
Regards,
Robert
