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: [email protected] > To: [email protected] > CC: [email protected] > > 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.
