Greetings to all Forum users,
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:
1. Installed Haskell Compiler GHC 7.0.2
------> Starting GHCi it from win 7 start menu, gives following output in a DOS-window:

.................................................................
. GHCi, version 7.0.2: [url]http://www.haskell.org/ghc/[/url]  :? 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.

2. Loaded cabal.exe from source (see introduction), copied it into C:\ghc\ghc-7.0.2\bin (which is added into %Path%-variables)
3. Loaded cabal-install-0.8.2.tar.gz as the site advises users that the packeage is needed for a clean install.
5. Opened new dos prompt window
6. typed "cabal update" (as advised by site), it did update the list and returned to user prompt mode
7. typed "cd C:\pathwhere\cabal-install-0.8.2.tar.gz" (switched into the directory where the cabal-install file is located)
8. typed "cabal install cabal-install-0.8.2", thereafter the installation started creating following output in the dos-box:

My Conclusion:
As one can easily see, the output indicates some errors, but i got no idea what mean. I continued trying to install my algebra package focusing on making it availible to the Dos-Interpeter from step 1.
9. 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.

Basically the cabal packaging system, or possibly the Hackage package repository, is crap. You can get around problems by installing the required dependencies directly. For some reason, this works. It is a mystery.
