Hello all! I'm extremely happy to report (thanks to invaluable help from Stephen) that my issues were my own dumb fault : ) — I was using LLVM 3.0's Clang but not its llc or opt. With some other tweaks to Stephen's above patch[1], we now have a perfectly working GHC-iOS on OS X 10.9 Mavericks. Hurray!
Cheers Luke [1]Stephen's work: http://ghc.haskell.org/trac/ghc/ticket/8125 http://ghc.haskell.org/trac/ghc/ticket/8126 http://ghc.haskell.org/trac/ghc/ticket/8127 On Mon, Aug 12, 2013 at 1:44 AM, Luke Iannini <lukex...@gmail.com> wrote: > Hi all, > > I tried this — building GHC HEAD configured to use the native code gen, > and then building the cross compiler using that, and got the same errors as > everything else thus far: > https://gist.github.com/lukexi/02366ed57171400b961a > > 10.9 Mavericks is likely coming out in less than a month, along with iOS7 > and Xcode5 final, so it's definitely worth sorting this out! > Not quite sure what to try next though... > > Best > Luke > > > On Sun, Aug 11, 2013 at 3:18 PM, Carter Schonwald < > carter.schonw...@gmail.com> wrote: > >> What if you build a copy of head with the native code gen.
