[Haskell-iPhone] ghc-iphone with recent OSX & XCode

[Stephen Blackheath [to GHC-iPhone]]

Thomas,

Good timing.  I just sorted this out.

The version I posted recently (namely 
ghc-iphone-binary-1.5-sdk-3.0.tar.bz2) was built with an old Xcode, 
against SDK 3.0. The symlink you describe is the correct thing to do.

cd /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin
sudo ln -s i686-apple-darwin10-gcc-4.0.1 i686-apple-darwin9-gcc-4.0.1

2. Inside the xcode_3.2.5_and_ios_sdk_4.2_final.dmg volume there's a 
directory called Packages, which the finder doesn't let you get to.  Go 
in with the command line and copy the file iPhoneSDK3_0.pkg onto the 
desktop or somewhere you can get to it with the finder.  Install that by 
double-clicking.

SDK3.0 seems like the best choice for the AppStore now, since it's the 
lowest you can get away with.  You may find that with SDK3.0 present, it 
will work if you set your project to iOS 4.2.  The other option, if you 
want to use the new SDK, is to build GHC-iPhone from source, which 
should not be difficult, though when I switched from SDK 2.2.1 to SDK 
3.0 I needed to make a minor change (I added this as a patch to the 
source code directory).

Newer versions of GHC are on their way for Android, and we will probably 
end up porting back to iPhone.  Keegan McAllister (kmc) is working on that.

Having said all that, I'm now getting link errors, like this:

Undefined symbols:
   "_OBJC_CLASS_$_NSAutoreleasePool", referenced from:
       objc-class-ref-to-NSAutoreleasePool in main.o
       objc-class-ref-to-NSAutoreleasePool in AppController.o
   "_OBJC_CLASS_$_NSTimer", referenced from:
       objc-class-ref-to-NSTimer in AppController.o
   "_OBJC_CLASS_$_NSValue", referenced from:
       objc-class-ref-to-NSValue in AppController.o
   "_OBJC_CLASS_$_NSBundle", referenced from:

I tried changing from gcc 4.2 to gcc 4.0 like this: project top level in 
the tree view and selecting GetInfo, then Build tab, then C/C++ compiler 
version to 4.0.

But that didn't work either.  Now I'm getting this:

/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/Frameworks/UIKit.framework/Headers/UILocalizedIndexedCollation.h:13: 
error: syntax error before 'AT_NAME' token

So, I'll see what I can do about this and post again.
