Here's exactly how to build the master-merge-ios branch
by Stephen Blackheath [to GHC-iPhone] 30 Aug '13

Stefan, Here is the exact procedure I just did to successfully build the GHC-iOS cross compiler: git clone git@github.com:ghc-ios/ghc.git ghc-ios cd ghc-ios git checkout master-merge-ios cp arm-apple-darwin10-bin/* ~/bin/ (<-- ~/bin is in my PATH) I edited ~/bin/arm-apple-darwin10-gcc to change the -march option to armv7, like this, because that's what my iPod touch has: TARGET_CFLAGS="-isysroot $TARGET_PLATFORM -march=armv7 -mcpu=cortex-a8 -mfpu=neon" git checkout master git remote set-url origin http://darcs.haskell.org/ghc.git/ ./sync-all --no-dph get wget http://hackage.haskell.org/trac/ghc/raw-attachment/ticket/7759/ios-patch-14… wget http://hackage.haskell.org/trac/ghc/raw-attachment/ticket/7760/ios-patch-15… cd libraries/base cat ../../ios-patch-14a-libraries-base.patch | patch -p1 cd ../../utils/hsc2hs/ cat ../../ios-patch-15a-against-hsc2hs-remove-HSC2HS_EXTRA-from-stage0-wrapper.patch | patch -p1 cd ../.. git remote set-url origin git@github.com:ghc-ios/ghc.git git checkout master-merge-ios cat > mk/build.mk HADDOCK_DOCS = NO BUILD_DOCBOOK_HTML = NO BUILD_DOCBOOK_PS = NO BUILD_DOCBOOK_PDF = NO SPLIT_OBJS = NO INTEGER_LIBRARY = integer-simple Stage1Only = YES DYNAMIC_GHC_PROGRAMS = NO GhcLibWays = v <ctrl-D> perl boot ./configure --target=arm-apple-darwin10 --prefix=/usr/local/ghc-ios-steve make When you get this: ghc-stage1: panic! (the 'impossible' happened) (GHC version 7.7.20130328 for arm-apple-ios): expectJust initTcInteractive just type 'make' again I am using: ghc-7.4.2 as my bootstrap ghc compiler thopminkringscrape:ghc-ios stephenblackheath$ llc --version Low Level Virtual Machine (http://llvm.org/) llvm version 3.0 Optimized build. Built Aug 10 2012 (18:51:37). Host: x86_64-apple-darwin12.3.0 Host CPU: i686 This is the head for master-merge-ios branch: commit 942b130ada7be3f608286da934026e2c162d9527 Merge: 97274b1 81d55a9 Author: Stephen Blackheath <..> Date: Thu Mar 28 23:51:02 2013 +1300 Merge branch 'master' into master-merge-ios > would you mind uploading somewhere a source tree that builds for you? Sorry - I'm not really able to do that at the moment. > you mean the architecture compiled for? armv7 vs armv7s? That's right. I have not actually run this version yet.

iOS cross compile instructions now on GHC wiki / progress update

All, Cross-compiling GHC to iOS: http://hackage.haskell.org/trac/ghc/wiki/Building/CrossCompiling/iOS Progress update: I've now submitted all the patches as tickets to GHC. I've hit a regression with http://hackage.haskell.org/trac/ghc/ticket/7722 (this was working in the old 'ios' branch at http://github.com/ghc-ios) but this won't stop trivial programs running. Steve
