[Insight-developers] Custom ITK class wrapping

[Zachary Pincus]

Hi folks -

Sorry to send this to both the users and developers list, but I'm  
hoping to get some advice on relatively deep ITK magic, so I'm not  
sure where best to ask.

My basic question is if anyone can give me any advice, tips, or  
warnings about creating a custom python wrapping library for ITK.

The basics of my problem are twofold:
(1) I wish to wrap some custom C++ classes I've written
(2) I've never managed to get the default python wrapper library to  
work on OS X, due to some sort of loader issues with huge libraries.  
(Perhaps this is fixed in the newest ITK releases, or under OS X  
10.4? I haven't tried in a while.)

At any rate, I'd like to wrap a narrow subset of ITK and my custom  
code into a (relatively) small python wrapper library. I know this  
isn't a "supported" procedure, and a lot of very confusing stuff is  
going on to get CMake, cswig, gccxml, and the rest to all cooperate  
and make things work. If anyone could give me a rundown of the basic  
issues involved here, and where I should start, I would be pretty  
grateful.

I've read through some of the contents of $ITK_ROOT/Wrapping, and it  
by and large makes sense -- but any details or hard-won insight into  
how to make this work in my own project would be really appreciated.

Thanks,

Zach
