Hey Stephen - more on cross compiling
by Stephen Blackheath [to GHC-iPhone] 14 Jan '13

Stephen, Gabor Greif had some cross-compiler changes checked in to mainline recently (see email below), so you should be able to get started with your Blackberry port. I'll re-do GHC-iOS against the latest master. Steve On 20/11/12 09:53, Gabor Greif wrote:> Hi Stephen, > > Ian merged the functionality (mostly?) to mainline 7.7.

Hi Luke, Thanks for the reply. I did make a separate env.sh with the info from the wiki, though a different filename is definitely a good idea. I've echoed back all of the variables after running the script and they are all reading correctly except Im not sure about path. I've run that script quite a few time in trying to get this running and I fear it may have made my path insanely huge.

Arm cabal
by Casey Basichis 25 Dec '12

25 Dec '12

Hi, I've been trying to get the iOS cabal running with no success. I do have GHC running on iOS otherwise. Here is some information. I installed the GHC-IOS haskell. Later I installed the Haskell Platform for working on the system (in case that could be the cause). I have run the cabal install commands (I pretty much always have to add sudo to get any of these commands working). During the install of the modified cabal I get a law of rawSystemExit's but it seems to install. I run the the env.sh (with the build dir set to my own) and try installing a package. One time it seemed to work: runOutput /usr/local/ghc-iphone/bin/arm-apple-darwin10-ghc ["--info"] etc every attempt since gives me this kind of path runOutput /usr/bin/ghc ["--info"] any idea how I can get cabal running for iOS?

cabal custom build type
by Stefan Kersten 19 Dec '12

19 Dec '12

hi, am i correct in assuming that packages with a 'Custom' build type (and corresponding Setup.hs) will not build with the current ghc-ios cross compilation setup? i am trying to port an existing application and one of the dependencies is 'syb', which fails to install. any known workarounds? thanks, <sk>

hi, LLVM 3.0 doesn't seem to build out of the box on 10.8, maybe something like the following could be added to the wiki: ### Building LLVM 3.0 on OSX 10.8 Building LLVM 3.0 on 10.8 fails; this [issue report](https://github.com/staticfloat/homebrew/commit/45151ab7defaf4341f16… provides a fix in the associated [patch](http://pastebin.com/raw.php?i=SP2YcKFx): $ curl http://pastebin.com/raw.php?i=SP2YcKFx | patch -p1 <sk>

cabal arch function
by Stefan Kersten 18 Dec '12

18 Dec '12

hi again, i am trying to compile the primitive library, which includes the following in its cabal file: if arch(i386) || arch(x86_64) { cc-options: -msse2 } during configuration the arm cross compiler (rightly) complains about the unsupported -msse2 option (see below). but why is that option even added to cc-options? shouldn't arch be arm or something similar when cross-compiling? the cabal docs are saying: "arch(name) Tests if the current architecture is name. The argument is matched against System.Info.arch on the target system. If the arch names match, this test evaluates to true, otherwise false. The match is case-insensitive." any help appreciated! thanks, <sk> runOutput /Users/skersten/dev/samplecount/ghc-ios/bin/arm-apple-darwin10-gcc ["-fno-stack-protector","-isysroot","/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk","-march=armv7","-mcpu=cortex-a8","-mfpu=neon","-L/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk/usr/lib/","/var/folders/O8/O8mOkxWPErOOmiDsQeAl2E+++TI/-Tmp-/92247.c","-o","/var/folders/O8/O8mOkxWPErOOmiDsQeAl2E+++TI/-Tmp-/92247","-D__GLASGOW_HASKELL__=705","-Ddarwin_HOST_OS=1","-Dx86_64_HOST_ARCH=1","-Idist/build/autogen","-Icbits","-I.","-msse2","-O3","-ftree-vectorize","-fomit-frame-pointer","-I/usr/local/ghc-iphone//lib/ghc-7.5.20121127/base-4.5.0.0/include","-I/usr/local/ghc-iphone//lib/ghc-7.5.20121127/include","-msse2","-O3","-ftree-vectorize","-fomit-frame-pointer","-L/usr/local/ghc-iphone//lib/ghc-7.5.20121127/base-4.5.0.0","-L/usr/local/ghc-iphone//lib/ghc-7.5.20121127/integer-simple-0.1.0.0","-L/usr/local/ghc-iphone//lib/ghc-7.5.20121127/ghc-prim-0.2.0.0","-L/usr/local/ghc-iphone//lib/ghc-7.5.20121127"] ("/Users/skersten/dev/samplecount/ghc-ios/bin/arm-apple-darwin10-gcc",["-fno-stack-protector","-isysroot","/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk","-march=armv7","-mcpu=cortex-a8","-mfpu=neon","-L/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk/usr/lib/","/var/folders/O8/O8mOkxWPErOOmiDsQeAl2E+++TI/-Tmp-/92247.c","-o","/var/folders/O8/O8mOkxWPErOOmiDsQeAl2E+++TI/-Tmp-/92247","-D__GLASGOW_HASKELL__=705","-Ddarwin_HOST_OS=1","-Dx86_64_HOST_ARCH=1","-Idist/build/autogen","-Icbits","-I.","-msse2","-O3","-ftree-vectorize","-fomit-frame-pointer","-I/usr/local/ghc-iphone//lib/ghc-7.5.20121127/base-4.5.0.0/include","-I/usr/local/ghc-iphone//lib/ghc-7.5.20121127/include","-msse2","-O3","-ftree-vectorize","-fomit-frame-pointer","-L/usr/local/ghc-iphone//lib/ghc-7.5.20121127/base-4.5.0.0","-L/usr/local/ghc-iphone//lib/ghc-7.5.20121127/integer-simple-0.1.0.0","-L/usr/local/ghc-iphone//lib/ghc-7.5.20121127/ghc-prim-0.2.0.0","-L/usr/local/ghc-iphone//lib/ghc-7.5.20121127"]) /Users/skersten/dev/samplecount/ghc-ios/bin/arm-apple-darwin10-gcc returned ExitFailure 1 with error message: cc1: error: unrecognized command line option "-msse2" cc1: error: unrecognized command line option "-msse2" program: int main(int argc, char** argv) { return 0; }

FFI for living in C
by Casey Basichis 02 Dec '12

02 Dec '12

Hi, I've been reading about the FFI for getting Haskell to communicate with C code (C++ really). My intention is to handle most of the app - the GUI events in C++ and sending all of the processing logic in Haskell - including a database etc. Is the FFI the right tool for a situation where, while used extensively, Haskell is more or less there to take in data, like lists and spit out data like vectors etc back to C. I am looking to get a few test running where I can pass data in an out of Haskell like vectors of floats. Also, I noticed on the wiki example: Haskell start c_main I was a little confused by this. Does Haskell load up first because its a library? I couldn't figure out where it was being called in the C code or why Haskell loads first. Not a biggie just a bit of an impediment in understanding how it all works.
