Hi Nick,
Your ITK build is certainly a mess :-)
Please follow the "Perestroika" procedure:
A) Delete the entire binary directory
where you were attempting to build ITK
B) Delete the entire binary directory
where you built CableSwig.
C) Delete the directory where you have
CableSwig sources.
D) Delete the directory where you have
ITK sources.
Take deep breath.
It's time for renovation...
E) Download ITK sources through CVS
The wrapping builds are green today
in the Dashboard.
F) Go to the Utilities directory and
download the CVS version of CableSwig
in that directory.
You should end up with something like
Insight/Utilities/CableSwig
G) Make sure that you are using CMake 1.8.3
H) Configure ITK using CMake.
*DO NOT* build in-source. (it seems that
you were doing that in you current built).
Select a binary directory different from
the source directory.
Make sure that you select the correct
version of the compiler. This is done in
the upper right menu of the CMake GUI.
Then
- Disable EXAMPLES
- Disable TESTING
- Enable SHARED_LIBRARIES
click Configure, and then click OK
I) Load the .sln project into VisualStudio.
*VERY IMPORTANT*: verify that your visual
studio do not think that the .txx files
should be compiled !!. Some users have
manually set that option in order to
see the source files in their project,
and cause havoc at compilation time.
J) Build this project. It should take about
15 minutes.
If the build fails, please send us any
error messages that you get.
K) If the build goes ok, then Quit VisualStudio
(close the project) and rerun CMake.
Enable Python wrapping.
Make sure that you select a consistent
set of Python interpreter and libraries.
E.g. you don't want to use the python
libraries of windows, with the python
interpreter of Cygwin.
L) Reload the project in VisualStudio
M) Build.
IF you get any build errors, please post them
to the list.
N) Set the PYTHONPATH variable according
to the instruction in the README file
Insight/Wrapping/CSwig/README
O) Try running any of the Python examples in
Insight/Examples
----
If you get in trouble in any of those steps
please let us know up to what step you were
doing OK.
Thanks
Luis
