OK, I'm underway on this.

First roadbump was:

You are using a new version of LLVM that hasn't been tested yet!
We will try though...


/usr/local/bin/llc: : error: unable to get target for 'arm-apple-darwin10', see --version and --triple.

which I figured out were because the homebrew LLVM 3.4 only includes host platforms by default (x86/x86-64)
Reinstalling it with all-targets enables them all:
brew install llvm --with-clang --all-targets --HEAD

Trying again now.

Update: I've got GHC HEAD building on 10.9 again, tonight I'll dive into the iOS patch!

if you're on 10.8, just DL the 4.6 CLI tools to get things working again.

If you're on 10.9, you'll need to use recent GHC head + CLANG HEAD, (ok, the most recent XCODE 5 dev preview CLI tools may have all the needed clang patches, but thats still needing its own validation, orthogonal to the IOS related issues )

Hi Stephen,

I installed 10.9 for another project and thus am in the middle of fixing up my system to be able to build GHC again, but I think I'm close — as soon as I have it going I'll try this.

In the meantime someone still on 10.8 should definitely try the patch!

Hope you're great!
Luke

Hi all,

A couple of months ago I got some patches applied to GHC mainline for the ability to cross compile to iOS. I've been doing other things and now I want to test those changes. The trouble is, I am having Apple trouble and I can't get Xcode to work.

If anyone is interested in testing it for me, I'd appreciate it.

The patch attached here needs to be applied to GHC head. Using this, I was able to get the cross compiler to build. The instructions are here:
