[Insight-users] Need tutorial tu use Itk with VS2005

[Michael Jackson]

This has got to be the most common error that I see when moving from  
Linux/Unix/OS X to Windows and it can be very difficult to diagnose  
when you are new to Windows.

Essentially, the problem is that for better or worse, all compiled  
projects that link together on Windows using Visual Studio MUST be  
compiled EXACTLY the same way regarding the threading model and debug/ 
release and also the same version of Visual Studio (including Service  
Packs).

Ignoring warnings will only send you down a path of trying to debug  
something that is not fixable. Period. Here are some examples.

Say I use ITK in a project and I have it compiled in Release mode. Say  
I now compile my project in Debug mode in order to actually debug my  
code. VS will throw a warning about conflicting libraries and to use  
to the /NODEFAULTLIB link flag. DO NOT DO THIS. Instead, go back and  
recompile ITK in Debug mode and install that OVER TOP of the original  
Release version of ITK. Now, go back and do a "Rebuild" of your  
project. Link warning is now gone and you can now safely debug your  
project without any side effects**.

  This same thing can happen if one of your projects is compiled as a  
Single Threaded model and another is compiled as a Multi-threaded model.

   And also watch out for either statically or dyamically linking to  
the C/C++ runtimes. This will cause some of the same issues as above.

  The problem becomes even more of a pain if you mix-and-match Visual  
Studio versions. Then you have to worry about the whole "Re- 
distributable" package for your project and Side-by-Side assemblies.

   So the short answer is this: If you are using a bunch of 3rd party  
libraries in your project be sure to compile them all with the same  
parameters.

**Again, I would _love_ to see ITK do the same thing Qt does and  
decorate the debug libraries with _debug or _d or D or something so  
that I can have both the Debug and Release libraries installed in the  
same location AT THE SAME TIME. Currently, I have to "install" the  
debug libraries, then rebuild my large project to debug, then  
"install" the Release version, then rebuild my project to test out the  
performance. Kind of a pain. Qt's use of decorated libraries makes  
this transition relatively less painless.

Hope some of that helps.
