<br>
One of my Macs is kept at 10.6.8 (with Xcode 3.2.6) because it's a<br>
system I still wish to support. However, I'd like to move to clang on<br>
it, if possible. I prefer to either install a precompiled binary<br>
distribution (if it exists) or compile it on my own, but for the<br>
moment I'd prefer to avoid installing it through macports.<br>
<br>
Looking at the LLVM releases downloads page, I see several downloads<br>
tagged "Darwin", but it doesn't specify what Darwin version is<br>
required for it to run (some of them say "Darwin 10.9", but is it<br>
Darwin 10.9 or OS X 10.9? On very older releases (the gcc front-end<br>
ones) I see Darwin10 binaries.<br>
<br>
I suppose there won't be any relatively recent binary distribution<br>
that I can use on Snow Leopard, so I guess I've to build it myself. In<br>
that case, should the 3.8.0 build out of the box? If not, is there any<br>
not too old release that would build out of the box? (when I say "out<br>
of the box", I mean that it passes all tests, and no custom patches<br>
are necessary).<br>
<br>
Thanks a lot in advance,<br>
