Build fails when using Xcode 5

For this ghc release cycle, I imagine it's ok to stay Arm 32bit only abi. ESP since the apple upstream arm 64 bit stuff for apple hardware hasn't landed in llvm main afaik. For any new abis for ghc, I really want to be systematic In how we design and test changes. Austin Seipp may have a more accurate / precise opinion since he's spent a lot of time making arm support work this year. Do we need to do anything to support targeting arm 64?

Hi Dominick! Yes, this should work swimmingly on the 5S in 32bit mode. We'll have to wait for Apple to merge their Arm64 patches [1] before we can add full 64-bit support (I can do the 64bit simulator right now though : )). (though I just saw this!

Hi all, Just wanted to let you know I've finished updating GHC iOS to support Xcode 5. The new scripts are at https://github.com/ghc-ios/ghc-ios-scripts/tree/xcode5 and you'll find updated instructions at http://ghc.haskell.org/trac/ghc/wiki/Building/CrossCompiling/iOS . Please let me know if you have any trouble! Cheers Luke

GHC build fails for Xcode 5 Final because of llvm-gcc-4.2 made obsolete
by Sergey Mikhanov 30 Sep '13

30 Sep '13

Hi, Using Xcode 5 Final for building GHC is not possible because of llvm-gcc-4.2 made obsolete. One of the scripts in ghc-ios-scripts (arm-apple-darwin10-gcc) invokes llvm-gcc-4.2 from Xcode setup: TARGET_BIN="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin" TARGET_GCC=$TARGET_BIN/arm-apple-darwin10-llvm-gcc-4.2 This binary is absent from Xcode 5. I tried using this configuration in arm-apple-darwin10-gcc: TARGET_BIN=/Applications/Xcode.app/Contents/Developer/usr/bin TARGET_GCC=$TARGET_BIN/gcc This results in this error: http://lpaste.net/93640. Looks like this gcc binary is just a link to clang. Is there any way around it? Thanks, Sergey Mikhanov

Problems during link with ghc-ios
by thomas burt 16 Sep '13

16 Sep '13

Hi all, I was able to build a ghc cross-compiler as per the wiki instructions (1), but I'm having trouble linking the static library in my application. Previously, I was producing a single lib using Stephen Blackheath's ghc-iphone binary with the flags "--make" and "-no-hs-main". I've been attempting to use the "-staticlib" and "-threaded" options to build the library, but Xcode reports missing symbols from both the RTS and my own code when it tries to link. Furthermore, when I run arm-apple-darwin10-ghc it reports that a number of libraries from the RTS have no symbols (although "nm" can find them just fine). Any suggestions for how to fix these problems would be appreciated! Thanks again, Thomas (1) http://ghc.haskell.org/trac/ghc/wiki/Building/CrossCompiling/iOS

Crash in freeHaskellFunPtr on iOS fixed in mainline
by Stephen Blackheath [to GHC-iPhone] 16 Sep '13

16 Sep '13

All, There was a bug where freeHaskellFunPtr would crash on iOS, which is now integrated into mainline GHC, so you may want to check this change out, especially if you are experiencing crashes. http://ghc.haskell.org/trac/ghc/ticket/8284 Steve

Building GHC cross-compiler failing on libffi
by thomas burt 14 Sep '13

14 Sep '13

Hi, I've just followed instructions for "Building a GHC cross-compiler for Apple iOS targets (1)", and I'm getting stuck during "make" while building libffi. Specifically I get errors like "no such instruction" and warnings about junk characters. I was able to build libffi using the build-ios.sh script found in libffi-3.0.13.tar.gz (2), but I noticed a less recent version (3.0.8) was listed in the "tarballs" file of the ghc distribution. Not sure if that makes any difference though. If anyone has suggestions for me, please let me know. Thanks in advance, Thomas (1) http://ghc.haskell.org/trac/ghc/wiki/Building/CrossCompiling/iOS (2) ftp://sourceware.org/pub/libffi/libffi-3.0.13.tar.gz

Here's exactly how to build the master-merge-ios branch

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!
