help needed with installing Liskell via cabal-insall

Fri Feb 27 00:16:06 EST 2009

(The gist of this message was previously posted as a thread with the
subject "unresolved Liskell installation problems," dated "Fri, 20 Feb
2009 17:24:19 +0900" on Haskell-Cafe (see
http://article.gmane.org/gmane.comp.lang.haskell.cafe/53245), but did
not receive any responses.  Since I was asked to post package
installation-related issues here, I am forwarding this message to this
list.)

Since reading through the forwarded log at the end of this message is
tedious, please allow me to summarize the problem as follows.

First, I used the following command to try to install liskell:

>darcs get http://code.haskell.org/liskell/

However, an error message appeared when I ran in Cygwin:

>./Setup.lhs configure

as follows:

>Configuring liskell-0.1...
>Setup.lhs: At least the following dependencies are missing:
>ghc-paths -any

Therefore, then installed ghc-paths, as follows:

>$ cabal install ghc-paths

In addition, following ctnd's advice of 24 January 2009 at 00:04 on
the above-mentioned blog, in Main.hs, I changed the Haskell code as
follows:

> -- GHC.runGhc (Just "/home/clemens/deploy/ghc-6.10.1/lib/ghc-6.10.1/") $ do
> GHC.runGhc (Just "/home/chris/.GHC/lib/ghc-6.10.1/") $ do

However, the building step still failed, as follows:

> $ ./Setup.lhs build
> Preprocessing library liskell-0.1...
> Setup.lhs: The program happy is required but it could not be found

However, strangely, "happy" is in fact installed and listed in the
PATH, as follows:

> $ which happy
> /cygdrive/c/Program Files/Haskell/bin/happy

Then, ctnd advised, on 27 January 2009 at 07:28, as follows:

>>[...]

>>I had the same problem:
>>
>>Configuring liskell-0.1...
>>Setup.lhs: At least the following dependencies are missing:

>>
>>I solved it by configuring as --user. I should've done this from the start as my GHC and cabal packages are all --user installed anyway.
>>
>>./Setup.lhs configure --user
>>./Setup.lhs build
>>./Setup.lhs install

I followed his advice, but then ran into the following error in the
building phase:

> Main.hs:218:0: parse error (possibly incorrect indentation)

These are lines 218-19 of my Main.hs file:

> partition_args :: [String] -> [(String, Maybe Phase)] -> [String]
> -> ([(String, Maybe Phase)], [String])

I tried merging line 219 into line 218, but the same error recurred.

In addition, the following error occured during the install phase:

>Setup.lhs: dist\build\liskell\liskell.exe: copyFile: does not exist (No such file or directory)

This is where I am unable to continue now.

Does anybody know how to resolve this package installation problem?
