Hi Stephen/all,

I got LLVM 3.0 installed and started building again but hit a very strange problem now wherein tons of layout-based code (as in http://en.wikibooks.org/wiki/Haskell/Indentation) is suddenly erroring out, e.g. compiler/coreSyn/CoreUnfold.lhs:481:2: parse error (possibly incorrect indentation or mismatched brackets) (some files also seem to be triggered by mixed tabs and spaces)

I can fix the errors one by one by converting the code to use more concrete indentation (like do thing1 thing2 ) but it's all over the tree.

Anyone have any idea what might cause this?

Cheers Luke

Luke,

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.

It's really easy to build llvm from source.

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

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:

OK! So just to summarize: Building GHC HEAD with LLVM 3.0 or 3.2 (using GHC 7.6.3 as the bootstrap) on OS X 10.9 DP5/Xcode 5 DP5 exhibits very strange behavior wherein layout-based code along with mixed-tabs-and-spaces code fails to parse correctly, with issues in hundreds of files in the GHC HEAD tree. I don't have a 10.8 machine to check if this is a 10.9 exclusive issue, so I'd love if someone can try using these binaries to build GHC HEAD: http://llvm.org/releases/3.0/clang+llvm-3.0-x86_64-apple-darwin11.tar.gz Building GHC HEAD with LLVM 3.3 or 3.4 works great as a regular compiler with the 10.9 workarounds I outlined in another thread, but fails when compiling as a cross-compiler (./configure --target=arm-apple-darwin10) with these errors: https://gist.github.com/lukexi/2b129f34fa027172c5ee So I'm between a rock and a hard place at the moment.
