Just a random note. jhc works fine on ARM, I have successfully run Haskell programs on on iPhone and a nokia n800 tablet compiled with it. jhc is, of course, still pretty unstable. but new developers are always welcome.

Re: Haskell on ARM (was Re: [Haskell-cafe] ANN: Topkata)
Hello, I have, on two occasions made an *unregisterised* of GHC for the ARM (specifically the Maemo on Nokia 770). Mostly I just followed the unregisterised porting directions in the GHC user manual. I documented one attempt here: http://hackage.haskell.org/trac/ghc/wiki/ArmLinuxGhc Note: This procedure is for building a version of GHC that runs on ARM and generates ARM code. So, it is not build a cross-compiler, just a native ARM compiler. The unregisterised build is not that useful because: 1. no FFI 2. uses trampolining for tail calls 3. no threads I think 4. some other stuff I have forgotten So, the next step is to registerise the build. This is online a few lines a code. Basically stuff like: 1. add ARM support to the evil mangler (basically, a few regexps to strip prolog and epilogue stuff from the ASM) 2. #define which registers exist and what they should be used for 3. implement the tail call ASM 4. define some aspects of the C calling convention 5. (Optional), implement native assembly generation This is not a lot of code. However, it is very low-level code. I think that doing a registerised build is pretty easy, the *second* time you do it. The big problem is that there is pretty much no documentation on how to do it. (The porting guide does tell you, very generally, what needs to be done). Also, running GHC on an emulated ARM processor is slow. I think it took GHC 6.4 8+ hours to build. Now that many of the extra libs have been split out into the extra libs package, that should help significantly with the build time. If any does attempt to build for the ARM, please, please, please, document what you do in the wiki. And, if you do, edit the wiki as you go, you definitely won't be able to remember what you did after the fact. (Or, at the very least, use some program to capture everything you do so that you can refer to it later). And, finally, I heard vague rumors a while ago that made me think that GHC 6.10 might have a pure ANSI-C backend? Is there any truth to this? That would make porting much easier if it meant you did not have to do steps 1-4. j. ps. I would be happy to try to answer any questions if someone tries a port. I would still like to run GHC on my 770, and I hope to own an iPhone if they fix a few ommisions (bluetooth keyboard support, and similar stuff).

This would be quite a coup if it could be made to run there! I'd be interested. We should start a wiki page for Haskell on the iphone.. It's an interesting idea, but I think it would need to be a cross- compiler. Does ghc support cross-compilation? The most obvious place to start I guess would be using -fvia-C and the C cross compiler that apple supply. I'll certainly be looking into this as soon as I get an iPhone (which unfortunately I need to wait for 3G one in Belgium).
