Updates:
Finally, I got the boundary file output working. Now it is able to export to the OpenFOAM mesh format. But I still need to do some optimization (hopefully to make it back to log-complexity with hash tables, thanks to c++11). Currently it takes too much time to build an OpenFOAM mesh manually.
Also I have tested the code on a clean ubuntu 64 environment with virtualbox, it seems to me anyone who wants to use it needs vtk and qt installed. Using synaptic package manager, search vtk and install the vtk-dev, libqvtk-dev packages.
Here is a screenshot of a multi-block mesh simulation:
