[vtkusers] python (2.7) problems compiling with MSVC 2010 64bit

Wed Jun 8 06:59:58 EDT 2011

Hi David,

I have tried python 2.6.7 with the same failure. Is this a known issue
for Windows? My configure settings are pretty straight forward: using
shared libs, paths to python/include/lib, enable wrapping, disable TK,
did I forget anything?

Is there somewhere a comprehensive information what should reside / be
copied where such that I can use vtk with python? I never saw one,
even under http://www.vtk.org/Wiki/VTK/Python_Wrapping_FAQ
I do not (in fact, can not) use vtkpython (that does not work for now
anyway). I need to create a custom python+vtk environment, totally
unregistered with the system (so I can have multiple versions).

Many thanks and best regards,
Dominik
