[Insight-users] Switched from cygwin to mingw - ITK compiles fine, but program does not.

[Seth Gilchrist]

Hello all,
Thanks for the help with reference to my question about cygwin yesterday.  I
took the recommendation to switch to mingw and after figuring out that I had
to set the advanced Cmake variables to:

ITK_USE_PTHREADS = FALSE
ITK_USE_WIN32_THREADS = TRUE

I was able to compile itk without problems.  However, the same cannont be
said for my program.  The program has a number of classes which are stored
in a directory structure and compiles without issue with g++ in linux.  My
CmakeLists.txt for my top level is below.  The linking errors are numerous
and run right out of the top of the command window, so I can't even see what
the first one was (very annoying).  Some examples are:

undefined reference to `itk::Object::GetDebug() const'
undefined reference to `itk::LightObject::Print(std::ostream&, itk::Indent)
const'
undefined reference to `itk::ExceptionObject::~ExceptionObject()'
undefined reference to `itk::Object::PrintSelf(std::ostream&, itk::Indent)
const'

I compiled itk with BUILD_SHARED_LIBS, BUILD_TESTING and BUILD_EXAMPLES all
set to false.

Any recommendations for trouble shooting these linking errors?

Thanks again for your time,
Seth
