[Insight-users] InsightToolkit-3.4.0 python wrap missing module _vcl_complex

[David Jarvis]

To insight-users at itk.org

I have for the first time tried to install
InsightToolkit-3.4.0 (and CableSwig-ITK-3.4.0), compiling from source
on a gentoo linux Intel machine with  gcc (GCC) 4.1.1 (Gentoo 4.1.1-r3)
and python 2.4.4

When trying to execute the python test script below  (after adding the
   appropriate directories to PYTHONPATH):
#! /usr/bin/env python
import InsightToolkit
print "hello itk"

the result is
Traceback (most recent call last):
   File "/home/djarvis/visiblehuman/ITKproj/pyexample1/testlib.py",  
line 2, in ?
     import InsightToolkit
   File "/usr/local/lib/InsightToolkit/python/InsightToolkit.py",  
line 1, in ?

   File "/usr/local/lib/InsightToolkit/vcl_complex.py", line 5, in ?
     import _vcl_complex
ImportError: No module named _vcl_complex

When I searched the list of installed files, as detailed from the  
command
make install
I can find files such as
Installing /usr/local/include/InsightToolkit/Utilities/vxl/vcl/ 
vcl_complex.txx
Installing /usr/local/include/InsightToolkit/Utilities/vxl/vcl/ 
generic/vcl_complex.h
Installing /usr/local/lib/InsightToolkit/WrapITK/ClassIndex/ 
wrap_vcl_complex.idx
Installing /usr/local/lib/InsightToolkit/WrapITK/ClassIndex/ 
wrap_VXLNumericsPython.idx Installing /usr/local/lib/InsightToolkit/ 
WrapITK/ClassIndex/wrap_vcl_complex.idx
Installing /usr/local/lib/InsightToolkit/WrapITK/ClassIndex/ 
wrap_vcl_complex.idx
Installing /usr/local/lib/InsightToolkit/WrapITK/lib/ 
VXLNumericsPython.py
Installing /usr/local/lib/InsightToolkit/WrapITK/lib/vcl_complex.py

There is nothing installed that looks like   _vcl_complex.py

Also searching the likely .so libraries with command 'nm' did not  
reveal anything declared
as _vcl_complex

I note some chatter on the web with some other user experiencing similar
problems on an ubuntoo machine, and a reply from Gaeten Lehmann Nov  
28 2007
suggesting that not both of WrapITK and ITK_CSWIG_PYTHON be used in  
the cmake build. I  have tried setting ITK_CSWIG_PYTHON to OFF as  
suggested, but the error persists

I would appreciate any help on this matter, and perhaps a pointer to  
more
detailed information on the build settings and testing and installing  
process
than I can find in the ITK software guide, which is thin on these  
details.
The document InsightStart.pdf, referred to in some web pages, does  
not appear
to be currently available in the Documentation section of the ITK  
website

Thank you for any help
