[ITK-users] Build errors in python wrapping of 4.10.0

[Michka Popoff]

Hi

I think this bug is not known. I had a look and could reproduce it with gcc 6.0.0, Cmake 3.5.2, Python 3.5.1 on OS X.
GCC 6 is using c++14 by default, but even with c++11 you would probably get the problem.
The problem is also there with the latest commit from the master branch.

Please note that we probably never tested Python Wrappings with c++11, even not speaking of c++14.

The problem seems to have appeared with this patch:
https://github.com/InsightSoftwareConsortium/ITK/commit/b6b9a8e8849da1edbf75f88e11adb8d8d15bb395

I removed the ITK_DELETE_FUNCTION macro from the itkTriangleHelper copy constructor, and was able to compile
with gcc 6. But it may just a side effect of that patch which is now only appearing with c++ >= 11.
It is weird that the problem seems to be only for the itkTriangleHelper class.

I will have to look what is the difference in the files generated for swig and what is exactly failing,
though I do not know how long it will take me. I hope I can do this this weekend.

Thanks

Michka
