[Insight-users] RE: Installing ITK on Mac OS X

[DZ]

I removed fink, and simply downloaded the latest
version of cmake from www.cmake.org. I then downloaded
itk-3.2.0.tar.gz and itk-2.6.0.tar.gz.  I set the
following in ccmake:

BUILD_SHARED_LIBS      OFF
BUILD _EXAMPLES         OFF
BUILD_TESTING             OFF

itk-3.2.0 compiled with those settings, however
compliling itk-2.6.0 gave the following errors:

I initially downloaded itk-3.2.0.zip and set all the
settings above to ON and I got a compilation error,
but since I don't need any of the above settings on, I
guess it is not that important. Anyways, I
redownloaded itk-3.2.0.tar.gz because I read several
things saying that .tar.gz was a better format to
download. Why is .tar.gz better? I then set the
settings above to off and compiled and 3.2.0 worked,
but earlier itk releases did not as discussed above.
Why will earlier releases (2.6.0) not compile?
Although I will not use a earlier release of itk, I am
still interested in understanding why I got the above
errors. Also, older versions of cmake would not
compile itk-3.2.0, why is this?

Thanks so much for the help.
