RE: [Haskell-cafe] build and use ghc's rts without a full unregistered ghc port?
I managed to get a hello world app working on the Wii! but I had to do some hacking of the generated C code because the devkitPPC is missing 2 posix headers referenced in the generated C code from Jhc. The functions the code used from those headers didn't seem completely essential. Basically I set the define JHC_isPosix to 0, commented out problem code. Of-course this isn't ideal, the solution would be to implement the missing headers for devkitPPC. > From: korca...@hotmail.com > To: mwot...@gmail.com > CC: haskell-cafe@haskell.org > Subject: RE: [Haskell-cafe] build and use ghc's rts without a full > unregistered ghc port? > Date: Sat, 24 Jul 2010 18:25:56 + > > > I did initially thought about it and had reservations but you convinced me so > I've been trying out jhc.

RE: [Haskell-cafe] build and use ghc's rts without a full unregistered ghc port?
I did initially thought about it and had reservations but you convinced me so I've been trying out jhc. Seems a lot more promising but unfortunately I had problems, here's my targets.ini: [wii] cc=powerpc-eabi-gcc byteorder=be gc=static cflags+=-DGEKKO -mrvl -mcpu=750 -meabi -mhard-float executable_extension=.elf bits=32 bits_max=64 Trying to compile a simple hello world haskell program resulted in the following error message: hs.out.elf_code.c:118:2: error: #error Could not determine bitsize hs.out.elf_code.c:150:24: error: sys/select.h: No such file or directory hs.out.elf_code.c:154:25: error: sys/utsname.h: No such file or directory ... ... For the first error I looked at the line and there is some pre-processor conditional code to determine the word size, this seems a bit odd since i've already specified these in the target.ini I would assume that they would get passed in to the compiler as extra defines. More depressing is the last two lines, which looks like a POSIX compatible environment is required with jhc it seems. Having a look at devkitPPC include directory it seems it does implement some POSIX headers but those particular headers certainly do not exist in there. Anyway I'll send a message to the jhc mailing list about it. > Date: Sat, 24 Jul 2010 20:51:39 +1000 > Subject: Re: [Haskell-cafe] build and use ghc's rts without a full > unregistered ghc port? > From: mwot...@gmail.com > To: korca...@hotmail.com > CC: haskell-cafe@haskell.org > > can't speak as to how difficult it is to get GHC built unregisterised, > but you might want to consider JHC if you don't need to use a lot of > Hackage.

Re: [Haskell-cafe] build and use ghc's rts without a full unregistered ghc port?
can't speak as to how difficult it is to get GHC built unregisterised, but you might want to consider JHC if you don't need to use a lot of Hackage. It compiles to C without a special RTS needed, which might make it a lot easier. mark On Sat, Jul 24, 2010 at 8:45 PM, Korcan Hussein wrote: > > Hi, I was just wondering if this is possible, I would like to use a gcc port > which cross compiles to the PPC architecture (Wii DevkitPPC to be > specifically: > http://wiibrew.org/wiki/DevkitPPC) for a platform that is not POSIX > compatible I > believe (at least not fully or maybe I'm wrong entirely). > > Ideally I would make an unregistered port of GHC but the problem is because > GHC > doesn't support true cross compiling yet I need to bootstrap on to the target > machine, which isn't running a POSIX environment. > > Still I did try to attempt to build with both the host and target set to > 'powerpc-unknown-linux' and build it with devkitPPC, I did use a custom > build.mk > which should pull in all the required dependencies, defines, etc for > devkitPPC. > > In the end I didn't get very far with it, it looked like missing posix > functions. > > I didn't want to spend to much time trying to make it work this way (maybe i'm > doing it wrong completely).
