[vtkusers] Build VTK for Windows XP 32bit on Window 7 64bit machine

[Bryn Lloyd]

Thanks. I will try this.

I have read that in general it is bad if an application depends on 
multiple versions of the same runtime library. I have now managed to get 
it to work on the faulty computer, by changing the order of linkage 
(link vtk dlls after other ones).

I think the conflict with the VTK dlls is/was related to the following:
  - VTK was compiled using VS2010, python wrapped using a Enthought 
python (VS2008, i.e. msvcr90.dll)
  - Our application is compiled using VS2010
  - Our application links to VTK and other libraries, some of these also 
depend on msvcr90.dll
  - There are two dlls with embedded manifests for different CRT.90 
versions (9.0.2x and 9.0.3x)

I wonder what would be proper way (best practice) to resolve this. For 
instance, will changing the link order work on all machines? But that 
might be a question for Microsoft/Visual Studio.

Thanks for the help
Bryn
