Re: [B2-devel] Inline Assembly Query

[Alexander v. G. <kal...@un...>]

Good morning,

I've actually got SheepShear compiling and running on 10.6 (minus jit)

http://pub.haikungfu.net/SheepShear-OSX.png

The trick is using an older Xcode (4.0.x) *or* using this:
https://github.com/kennethreitz/osx-gcc-installer

Right now i'm trying to figure out a build system outside of
Xcode for SheepShear on OS X as I *HATE* how messy Xcode is.
(to get the result above, I just used the autoconf stuff in src/Unix.

Thanks!
