[Haskell-iPhone] More arm-apple-darwin10-ghc trouble

Tue Dec 24 00:14:57 UTC 2013

Hi Schell,

If you're building onto a 4S/iPad4 or later, you're probably partially
running into the thing I mentioned wherein the arm-apple-darwin10-clang
script isn't quite correctly generating fat binaries for armv7 and armv7s
yet. I reverted it back to just doing armv7s (you'd have to switch it to
armv7 if you wanted an earlier device):
https://github.com/ghc-ios/ghc-ios-scripts/blob/master/arm-apple-darwin10-clang

You'll have to rebuild GHC with this :P.

Also, in "Build Settings", change "Architectures" to "Standard
Architectures (armv7, armv7s)" (as opposed to "(including 64-bit)") which
should fix the Arm64 messages (just added this to the wiki — we're awaiting
llvm code from Apple before we can support Arm64), and possibly set "Valid
Architectures" to just armv7s or armv7 depending on which device you're
building for until we get the fat stuff figured out.

Cheers
Luke
