Here it is :
        $ export PYTHONPATH=/usr/local/lib/ITK-4.1/Python
        $ export LD_LIBRARY_PATH=/usr/local/lib
        $ python -c "import itk; itk.force_load()"
        PySwigIterator not found in module ITKPyBase because of exception:
         'module' object has no attribute 'PySwigIterator'
        PySwigIterator not found in module ITKPyBase because of exception:
         'module' object has no attribute 'PySwigIterator'
        
        Traceback (most recent call last):
          File "<string>", line 1, in <module>
          File "/usr/local/lib/ITK-4.1/Python/itkExtras/__init__.py", line 101, in force_load
            getattr(itk, k)
          File "/usr/local/lib/ITK-4.1/Python/itkLazy.py", line 44, in __getattribute__
            value = namespace[attr]
        KeyError: 'PySwigIterator'

I'm now trying to reinstall it all, with other swig version.

* cvs installed in /usr/local/WrapITK and /usr/local/WrapITK/bin/cswig
as the executable
* debian packaged version (toggling ITK_USE_SYSTEM_SWIG flag in ccmake
menu)


Configuring it, cmake return the following (which was already the case
with my previous compilation) :
        
         Warning: No template declared for itk::Mesh. Perhaps should you turn on more WRAP_* options?
        
         Warning: No template declared for itk::MeshSource. Perhaps should you turn on more WRAP_*
         options?
        
         Warning: No template declared for itk::ImageToMeshFilter. Perhaps should you turn on more WRAP_*
         options?
        
         Warning: No template declared for itk::MeshToMeshFilter. Perhaps should you turn on more WRAP_*
         options?
        
         Warning: No template declared for itk::BinaryMask3DMeshSource. Perhaps should you turn on more
         WRAP_* options?
        
I tried to turn ON all wrapper flag except languages and doc ones (tcl,
perl, etc.), but I still have this warnings. With ITK_WRAP_GCCXML ON,
compilation will fail. But I'm rather doubt that I need it, so this
isn't important to me.

Using the debian swig version, the following error ISN'T return, but it
is returned with both cvs and ITK provided versions :

         CMake Warning (dev) at /usr/share/cmake-2.8/Modules/ExternalProject.cmake:167 (message):
           unknown ExternalProject_Add keyword: PCRE
         Call Stack (most recent call first):
           /usr/share/cmake-2.8/Modules/ExternalProject.cmake:1131 (_ep_parse_arguments)
           Wrapping/Generators/SwigInterface/CMakeLists.txt:44 (ExternalProject_add)
         This warning is for project developers.  Use -Wno-dev to suppress it.
        
For now I recompile with the debian swig configuration, without gccxml,
I will let you know what it gives.

Kind regards,
Mathieu
