Try llvm version 3.0 - that's what I'm using, and it definitely worked before. llvm-3.1 is broken for GHC+ARM. As for llvm >= 3.2, I'm not sure if it's been fixed yet, but it wasn't working last time I tried a couple of months ago. I think this was because llvm is getting fussier about its input and GHC hasn't been "tightened up" yet.<br>
<br>
It's really easy to build llvm from source.<br>

You are using a new version of LLVM that hasn't been tested yet!<br>
We will try though...<br>
/usr/local/bin/llc: : error: unable to get target for<br>
'arm-apple-darwin10', see --version and --triple.<br>
<br>
<br>
which I figured out were because the homebrew LLVM 3.4 only<br>
includes host platforms by default (x86/x86-64)<br>
Reinstalling it with all-targets enables them all:<br>
brew install llvm --with-clang --all-targets --HEAD<br>
<br>
Trying again now.<br>

if you're on 10.8, just DL the 4.6 CLI tools to get<br>
things working again.<br>
<br>
If you're on 10.9, you'll need to use recent GHC head +<br>
CLANG HEAD, (ok, the most recent XCODE 5 dev preview CLI<br>
tools may have all the needed clang patches, but thats<br>
still needing its own validation, orthogonal to the IOS<br>
related issues )<br>

Hi Stephen,<br>
<br>
I installed 10.9 for another project and thus am in<br>
the middle of fixing up my system to be able to<br>
build GHC again, but I think I'm close — as soon as<br>
I have it going I'll try this.<br>
<br>
In the meantime someone still on 10.8 should<br>
definitely try the patch!<br>

Hope you're great!<br>

Hi all,<br>
<br>
A couple of months ago I got some patches<br>
applied to GHC mainline for the ability to cross<br>
compile to iOS. I've been doing other things and<br>
now I want to test those changes. The trouble<br>
is, I am having Apple trouble and I can't get<br>
Xcode to work.<br>
<br>
If anyone is interested in testing it for me,<br>
I'd appreciate it.<br>
<br>
The patch attached here needs to be applied to<br>
GHC head. Using this, I was able to get the<br>
cross compiler to build. The instructions are here:<br>
