[Insight-users] Compiling WrapITK on Windows XP

[Sven Prevrhal]

(And RE: [Insight-users] Passing ITK objects from Python to C code of a
Python extension)

Thanks Gaëtan,

So I tried building with MSVC 2003.NET and failed because the compiler has a
65,536 line limitation. Then I build with MSVC 2005 C++ Express and no
compiler errors were issued. However, the INSTALL target complained:

52>C:/packages/Insight-CVS-VC2005/Wrapping/WrapITK/Modules/Base/cmake_instal
l.cmake:141:
52>FILE INSTALL cannot find file
"C:/packages/Insight-CVS-VC2005/bin/Release/SwigExtras.py" to install.

I did find a SwigExtras.i, .h and .cmake in the sources but that apparently
did not get compiled into a swigextras.py. When I rebuilt the _BasePython
target and (automatically selected) the dependent targets, that procuded
swigextras.py in the bin/Release/ directory
The INSTALL target (after a recompile of a bunch of apparently altered
projects, including the examples was automatically triggered) then also
installed. I can do
>>>import itk
now, great!

So what triggers the MSV IDE to reload some of the projects after the
initial build and causes them to be built again for the INSTALL target?
 
Thanks,
Sven

it works for sure with visual studio express 2005
