[vtkusers] TaskParallel.cxx example -> vtkCompositeRenderManager error!

[Peter Schmitt]

I am having trouble getting the TaskParallel.cxx example working.

I can compile & link the application, but I get an error once I do an mpirun:

[snip]
[pschmitt at host TaskParallelism]$ mpirun -np 2 -machinefile
~/machine_file TaskParallelism MPI
ERROR: In /software/linux-sles8-ia32/vizdev/vtk-nvgl-mpi-4.4.2-gcc-r1/src/Parallel/vtkParallelRenderManager.cxx,

vtkCompositeRenderManager (0x897e758): Must set Controller and
RenderWindow before starting interactor.

vtkCompositeRenderManager (0x897e6e0): Must set Controller and
RenderWindow before starting interactor.
[/snip]

I have added the following to my header:
#define VTK_USE_MPI 1
... but I get the same problem.

Any ideas of what to do?  Please note that I do not have cmake (and I
would like to avoid using cmake, if possible...)

Thanks!
Pete

I created a makefile:

OBJECTS = TaskParallelism.o task1.o task2.o

TaskParallelism : $(OBJECTS)
        $(CXX) $(LIBS) -o TaskParallelism $(OBJECTS)
