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.
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
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:
"_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:
error: syntax error before 'AT_NAME' token
So, I'll see what I can do about this and post again.
