Install Haskell module on Windows 7
Yesterday I tried to install a Haskell-module via cabal, in order to get aquainted with the installation of modules in Haskell. I had to install cabal first.
My System: Windows 7
Haskell-Compiler Version: GHC 7.0.2 (Link http://www.haskell.org/ghc/download)
Cabal: http://haskell.org/cabal/download.html
I will describe the process step by step, hoping that you may specify my wrong doings during both cabal and the package installation with cabal.
The procedure:
Installed Haskell Compiler GHC 7.0.2
Starting GHCi it from the Windows 7 start menu, gives following output in a DOS-window:
GHCi, version 7.0.2: Website :? for help . Loading package ghc-prim ... linking ... done. Loading package integer-gmp ... linking ... done. Loading package base ... linking ... done. Loading package ffi-1.0 ... linking ... done. Prelude>So far so good: Every function inside the base packages is accessible and functions just the way its supposed to.
Conclusion: The GHCi installation contains no erroneous steps.
Downloaded
cabal.exefrom source (see introduction), copied it into C:\ghc\ghc-7.0.2\bin (which is added into %Path%-variables)- Downloaded
cabal-install-0.8.2.tar.gzas the site advises users that the packeage is needed for a clean install. - Opened new dos prompt window
- Typed
cabal update(as advised by site), it did update the list and returned to user prompt mode - Typed
cd C:\pathwhere\cabal-install-0.8.2.tar.gz(switched into the directory where the cabal-install file is located) Typed
cabal install cabal-install-0.8.2, thereafter the installation started creating following output in the dos-box:Resolving dependencies... Downloading containers-0.3.0.0...

As one can easily see, the output indicates some errors, but I got no idea what they mean. I continued trying to install my algebra package focusing on making it availible to the Dos-Interpeter from step 1.
Again in dos-box input prompt, I typed
cabal install constructive-algebra, that created this output:Resolving dependencies... cabal: cannot configure algebra-0.0.0.1. It requires base >=3.0 && <4.1 For the dependency on base >=3.0 && <4.1 there are these packages: base-3.0.3.1, base-3.0.3.2 and base-4.0.0.0. However none of them are available. base-3.0.3.1 was excluded because of the top level dependency base -any base-3.0.3.2 was excluded because of the top level dependency base -any base-4.0.0.0 was excluded because of the top level dependency base -any
I suppose that the package is not installed. I need someone who can explain, what exact steps I need to do in order to get modules working.
Thanks for reading this post and answering in way that makes me understand it AND the Interpreter and Compiler working.
The easiest way is to get the Haskell Platform like DasBoot recommended, but I'll try and answer your questions anyway:
1) For the first part of your question, your installs are failing because something's wrong with your path. the tool "ar" couldn't be found. ar is used when creating libraries. If you type just "ar" in a command window it should return something like
Usage: ar [emulation options] [-]{dmpqrstx}[abcfilNoPsSuvV] [member-name] [count ] archive-file file... ar -M [
If it doesn't then you need to add the folder containing ar (probably C:\ghc\ghc-7.0.2\mingw\bin) to your path env variable in windows.
2) Your algebra library won't install under 7.0.2, atleast not out of the box. Algebra has a dependency listed as "Dependencies: base >=3.0 && <4.1"
but ghc 7.0 comes with base 4.3. Which is why you received:
cabal: cannot configure algebra-0.0.0.1. It requires base >=3.0 && <4.1
For the dependency on base >=3.0 && <4.1 there are these packages:
base-3.0.3.1, base-3.0.3.2 and base-4.0.0.0. However none of them are available
Luckily, this can easily be fixed for this particulair package. just do
cabal unpack algebra
cd algebra-0.0.0.1
notepad algebra.cabal
change the 4.1 to a 4.4
cabal install
and that should do it
I installed the full package from Download Haskell This package includes cabal. I'm running it on win7, and haven't had any problems so far.
And FWIW, if you click on the download link in your post and then try to download the latest version there is a big message which suggests downloading the haskell platform from the link I gave.
the package name is constructive-algebra but what is it's module name? That module name is what you should use in ghci.
