[Insight-users] itk python wrapping failing on Win

Tue Jun 5 07:22:16 EDT 2012

Thanks Alex,
I checked for whether ITK_EXPORT is defined in itkProcessObject and similar files. The mouse-over didn't work (stayed empty, even after IntelliSense completed) but typing ITK_EXP and Alt-right-arrow word-complete worked and showed the macro in itkMacro.h where I also found the code. So there is some evidence the macro is defined and the errors I see are related to something other than ITK_EXPORT. 

Re unchecking ITK_WRAP_EXPLICIT, I tried that and get new errors, they are all like this one:

Generating itkScalarImageToTextureFeaturesFilter.xml
Compiler "cl" is not supported by GCC_XML because none of 
the Vc6, Vc7, Vc71, Vc8, Vc8ex, Vc9, Vc9ex or Vc10 support directories exists.
Could not determine GCCXML_FLAGS setting.
Project : error PRJ0019: A tool returned an error code from "Generating itkScalarImageToTextureFeaturesFilter.xml"

Is there a guide on the ITK_WRAP Cmake macros - ITK_WRAPPING, ITK_WRAP_EXPLICIT, ITK_WRAP_GCCXML - what thety are and in what combination they can/should be used?

If I find a way to successfully compile, I will gladly contribute!

dear sven,

you re getting different errors messages, that s progress :-)

I never met that specific error before but, it's likely to be related to the window specific all import/export feature. If this is the case, this is supposed to be made transparent through the definition of ITK_EXPORT at configuration time. each itk class declaration should use it ( class ITK_EXPORT itkMyClassName ...). Can you check if in the declaration of itkProcessObject the keyword is there and as the right value (in MSVC you can move your mouse over the symbol to see it's definition, if it s empty, you have a problem).

this is a windows issues and, from what I see, not necessarily related to wrapping.

I wouldn't use EXPLICIT. Just use normal wrapping (there is an extra advanced flag for EXPLICIT instanciation, that is supposed to fasten the compilation of the wrapping if you use several language by first explicitly instantiating some of the template, and then wrapping those, switch it off).

I guess it works for them :-)

More seriously, I just checked the dashboard sand indeed, there is not a lot of windows machine (ihpc @ NLM, redwall @ kitware, factory @ kitware which has a different purpose, ...). Maybe it s time to call for contribution. I will see if I can resurrect one of the machine that gaetan was using for the wrapping.

Maybe you would also like to contribute, even only on-time experimental build so we can see more in details your errors? within MSVC just build the Experimental project (which is skipped by default when you BUILD_ALL), from the command line you can run:
ctest -D Experimental.

regards,

alex.
