That was me. Our discussion is here: <http://public.kitware.com/Bug/view.php?id=9839> >So, maybe this is just a marketing thing? Definitely partly. Apple touts the 64 bit thing in its marketing: <http://www.apple.com/macosx/> On Thu, 6 May 2010 08:13:47 -0500, Richard Wackerbarth said: >However, it will be a compatibility issue. Things evolve.

I agree with your sentiment, but a correction is in order: 10.6 can still run PowerPC executables (under Rosetta), but Rosetta is no longer installed by default. It's clearly on it's way out.

Right now having one binary seems cleaner, For Mac OS anyway, you'd still have 'one binary' thanks to the 'universal binary' concept.

We submit several nightly 64 bit builds, and I see no more problems than 32 bit. What problems? -- ____________________________________________________________ Sean McBride, B.
