Content-Type: text/plain; charset=ISO-8859-15; format=flowed
Hey,
I have installed haskell-plarform 2013.2.0.0 on windows 8.
I have MinGW + Msys isntalled.
I am trying to install some package with cabal. So I do:
cabal install netwire
in the msys console. Now I get:
cabal.exe: The program ghc-pkg is required but the version of c:\Program
Files
(x86)\Haskell Platform\2013.2.0.0\bin\ghc-pkg.exe could not be determined.
ghc-pkg.exe exists at the given position. What am I missing?
Thanks!
Nathan

Fishing for an answer...
What is the output of
> ghc-pkg list
Also, even though we are in 2013, I still personally avoid spaces in paths
for programs in windows that I'm going to use from the shell.

is there a typo in the tutorial? http://www.haskell.org/tutorial/io.html
sequence_ :: [IO ()] -> IO ()
sequence_ [] = return ()
sequence_ (a:as) = do a
sequence as
Shouldn't that last line be the following? (if so could someone please
report it? i don't know where to report typos/bugs in the tutorial)
sequence_ (a:as) = do a
sequence_ as

I reinstallesd haskell platform without spaces. Something changed!
A first attempt to cabal.exe update resulted in a segmentation fault,
the second worked. Now if I do:
cabal install netwire
I cet:
$ cabal install netwire
cabal.exe:
nothing else ...

Hi Nathan
I think that looks like a positive step.
What happens if you try to cabal install one of netwires dependencies - e.g
"semigroups" which doesn't have so many dependencies itself.
Again I'm fishing for an answer, but if semigroups installs that would
indicate that `cabal install` is working.

Yes, you are absolutely right.
By the way, this is not "the" tutorial, it is just one particular
tutorial (and a very old one at that). Yes, I know its URL is
haskell.org/tutorial, that is a historical accident rather than a
blessing of canonicity.
I am not sure who has access to the website to be able to fix it.

Hey,
Unfortantly same result:
cabal install semigroup
cabal.exe:
I also tried zlib (which is already installed), same result.
Any remaining Ideas?
Thanks!
