There're lots of discussion over it (actually I've not even noticed that when I installed Lion DP1 the first time). But I still keep suspicious about that because currently the simulator part of iOS SDK (including the simulator itself is i386 32-bit) is 32-bit. If Apple drops 32bit support for Lion eventually, they'll have to prepare two different set of SDKs for both SL and Lion, and this seems breaking its *universal* rule, not mention plenty of other excellent 32 bit applications.<div> <br></div><div>Nevo<br><br><div class="gmail_quote">On 8 May 2011 21:08, Robby Findler <span dir="ltr"><<a href="mailto:robby@eecs.northwestern.edu">robby@eecs.northwestern.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> Does this mean that Lion insists on all apps being 64bit?<br> <br> Robby<br> <br> On Sat, May 7, 2011 at 3:19 PM, Stephen De Gabrielle<br> <div class="im"><<a href="mailto:stephen.degabrielle@acm.org">stephen.degabrielle@acm.org</a>> wrote:<br> </div><div><div></div><div class="h5">> I get it too.<br> ><br> > I'm just updating to lion p2r2, and will install Xcode 4.1 Developer Preview 4.<br> ><br> > Have you had any luck?<br> ><br> > The only thing I'm going to vary from the normal build instructions is<br> > to specify 64 bit as per<br> > * Under Mac OS X 10.6 and later, `configure' by default selects<br> > 32-bit mode for building Racket.
