Hi I am just starting to learn Haskell (and FP in general). I've printed a copy of Yet Another Haskell Tutorial[1], and I wanted to work through it simultaneously using Ghc and Yhc. I've done this so far: % darcs get --partial http://darcs.haskell.org/yhc % scons But I get this error:
darcs get --partial --repo-name=depends/cpphs http://www.cs.york.ac.uk/fp/yhc/dependencies/cpphs
darcs failed: Failed to download URL http://www.cs.york.ac.uk/fp/yhc/dependencies/cpphs/_darcs/patches/2005122014... : HTTP response code said error
Running scons again give the following output:
40> ../Documents/Development/haskell/yhc % scons scons: Reading SConscript files ... Building version 0.7.0-20080514104547-custom. Checking for architecture...

Can anyone help me get Yhc building? Thanks Ashley [1] http://en.wikibooks.org/wiki/Haskell/YAHT -- http://www.patchspace.co.uk/ http://aviewfromafar.net/
Hi Ashley, Unfortunately Yhc is not that well maintained or usable - the GHC compiler is a lot more robust. If you want to work through something like YAHT with two compilers, I'd recommend Hugs and GHC.

Weird. I will check this one out - sounds very suspicious.

It looks like you are building on Mac, which I know people have had difficulty with in the past. I'm not sure if anyone has figured it out yet? Thanks Neil

Hi Neil I was under the impression that the Yhc was still being developed, although the repo has no patches for the last few months. What's its likely future? The reason I was looking at Yhc is that in the long run (aka when I get time) I'd like to learn more about compilers and virtual machines. So I'm using GHC to learn Haskell because I know it will work, but my interest was in Yhc as project rather than just a Haskell compiler. Yhc looks a lot more approachable (I think GHC is something like 100kloc?) and there's already some work done to make it compile to other environments, so I figured it'd be more fun to hack. Would Yhc be suitable for my learning purposes or could you recommend something else?

Looks like the patch file is just plain missing.

Yeah - I'm using OS X 10.5. I could try it in a FreeBSD or Linux VM, although if the cpphs repo is unavailable I don't suppose I'd have much luck. Incidentally I did try replacing the cpphs darcs repo with an unpacked tarball source[1], but that doesn't help. It's also interesting to note that cpphs (version 1.3) is in MacPorts and compiles fine. I haven't looked at it further, I simply carried on working with GHC alone.
