I'm trying to install quickcheck 2 via cabal on Ubuntu 10.04. No matter what I try to do, I always end up with the following:
$ cabal list quickcheck
* QuickCheck
Synopsis: Automatic testing of Haskell programs
Latest version available: 2.1.1.1
Latest version installed: 1.2.0.0
Homepage: http://www.cse.chalmers.se/~koen
License: BSD3
This is on a clean Ubuntu 10.04 with only the ghc6 and cabal-install apt packages installed. I had installed the binary package via cabal before trying to install quickcheck.
It tells me 2.1.1.1 is available, but it only ever installs 1.2.0.0. Why can't I get it to actually install the latest version?
$ cabal install --dry-run quickcheck

In order, the following would be installed (use -v for more details):
QuickCheck-1.2.0.0
I'm not sure why it chooses the old version, but you can just do:
$ cabal install --dry-run quickcheck-2.1
Resolving dependencies...
In order, the following would be installed (use -v for more details):
mtl-1.1.0.2
QuickCheck-2.1
You can be more specific in the version number, but you don't have to.

Following the instructions from this post on how to update cabal-install, I seemed to be able to install the latest version (or at least some version > 1.18, which is what I wanted.
$ cabal install Cabal cabal-install

However, when I tried cabal sandbox, it failed, so I checked cabal --version.
$ cabal --version
cabal-install version 1.16.0.2
using version 1.16.0 of the Cabal library
As you can see, the version is not the one that cabal claimed to install.
Adding ~/.cabal/bin to my path did nothing to help. (Yes, I did restart my terminal).
$ echo $PATH
<snip>:/home/kavi/.cabal/bin
$ cabal --version

I tried restarting my computer, but still:
$ cabal --version
cabal-install version 1.16.0.2
using version 1.16.0 of the Cabal library
I am using Ubuntu 14.04.
You should add /home/kavi/.cabal/bin to the beginning of the $PATH.

% echo $PATH

% which cabal

I try install install glib via cabal

Failed to install glib-0.13.0.7
cabal: Error: some packages failed to install:
glib-0.13.0.7 failed during the configure step. The exception was:
user error (The package 'glib' requires Cabal library version -any && >=1.18
but no suitable version is installed.)
evgeny#virtuos:~$ cabal --version
cabal-install version 1.20.0.3

what's wrong?
OS: Ubuntu 14.10
Cabal 1.20.0.3
GHC: 7.6.3
Run cabal install cabal-install. Daniel Wagner's suggestion will most likely provide different results than cabal --version.
I just did a fresh install of GHC 7.6.3, followed by installing the latest platform. But when I run cabal update, I get:
$ cabal --version
cabal-install version 1.16.0.2
using version 1.16.0 of the Cabal library
$ cabal update
Downloading the latest package list from hackage.haskell.org
cabal: <file descriptor: 8>: does not exist
What file descriptor is this referring to, and how can I fix this problem?
I've reported this issue on github but haven't gotten any help.
I'm trying to install Yesod on my Mac (running Mavericks), but installation fails because of an error installing Persistent. Specifically, cabal install persistent yields:
Failed to install persistent-1.3.0.2
Updating documentation index /Users/Max/Library/Haskell/doc/index.html
cabal: Error: some packages failed to install:
persistent-1.3.0.2 failed during the building phase. The exception was:
ExitFailure 11
(The full output is available as a gist)
I don't think this is an issue with conflicts, because I ran rm -rf ~/.ghc ~/.cabal before trying this (though I think 3 globally installed packages might not have been erased—unsure).
I'm using the latest Haskell Platform with the ghc-clang-wrapper script.
Cabal versions:
$ cabal --version
cabal-install version 1.16.0.2
using version 1.16.0 of the Cabal library
GHC version:
$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 7.6.3
Reinstalling Haskell platform allowed me to install Persistent, but the real issue was that I needed to install gcc48. Installing this cleared everything up. https://stackoverflow.com/a/21285413/1176156
I need to configure eclipsefp and install hoogle and scion-browser for setting up a haskell project using mysql.
I tried to install hoogle and scion-browser from Eclipse -> Preference -> Helper executable, and also from the terminal, however unsuccessfully.
cabal install hoogle
and
cabal install scion-browser
fail, throwing the following:
cabal:codec.compression.zlib: premature end of compressed stream.
Edit:
It may be a problem with the cabal version?
If I run cabal --version in terminal, it says:
cabal-install version 0.14.0
using version 1.14.0 of the Cabal library
If I perform cabal update nothing happens.
However, in Eclipse -> Helper Executables there are two versions available:
version 0.14.0
version 1.18.0.2
They are located at different locations, I checked the second one to be used.
in my case, the downloaded package is broken, figured it out by running cabal install -v package-name, removed it manually and finally worked
