Does anyone have suggestions about how to install pandoc on Arch? I am trying to install pandoc-static from here: https://aur.archlinux.org/packages/pandoc-static/ , although it appears to be conflicting with my xmonad installation (I use xmonad as a TWM): [grease-lightning]/home/.../builds/pandoc-static$ makepkg -s ==> Making package: pandoc-static 1.15.0.6-1 (Sun Aug 16 23:18:48 PDT 2015) ==> Checking runtime dependencies... ==> Checking buildtime dependencies... ==> Retrieving sources... -> Found pandoc-static-1.15.0.6-1.tar.xz -> Found pandoc-static-1.15.0.6-1.tar.xz.sig ==> Validating source files with sha512sums... pandoc-static-1.15.0.6-1.tar.xz ...

Aborting... I am afraid of breaking my xmonad TWM if I force the reinstall. What should I do? Perhaps I should install Pandoc via sudo cabal install --global pandoc? If so, how should I install cabal? I was thinking that I should download it from here: https://www.haskell.org/cabal/download.html Any suggestions or recommendations are appreciated. I am also happy to clarify anything.

I was following [this](https://www.haskell.org/cabal/) tutorial on how to install cabal on linux. So far, I successfully installed cabal-install from apt:

sudo apt install cabal-install

However, at the step where they upgrade cabal with cabal itself, I encounter this error:

$ cabal install cabal-install Cabal

I couldn't find exactly

(line 9 of the log) on google. I tried to install only cabal-install and Cabal separately with the cabal cli, but I got the exact same error each time. How do I work around this error and successfully update cabal?

I have installed FreeBSD 10.2-RELEASE 32-bit and I am trying to use Haskell on it. I have installed package ghc-7.10.2 with pkg and then installed package hs-cabal-install-1.22.6.0 from /usr/ports/devel/hs-cabal-install. Now, when I run cabal update I get: $ cabal update Downloading the latest package list from hackage.haskell.org Segmentation fault (core dumped) Running it as root causes the same problem. I have been searching on different search engines but found no article describing this specific problem. Can you give me some hint on how to solve this problem or where I can find some documentation about it?

I set up a NixOS system on KVM and installed the haskelPlatform package.

I've just installed and updated cabal, but it is still using the original version (1.16.0.2) instead of the updated 1.22.4.0. The commands I have run, after installation through apt-get:

$ cabal update
$ cabal install cabal-install cabal

This built and installed the new version of cabal-install and cabal as was expected, but when I do cabal --v it still prints:

$ cabal --v
cabal-install version 1.16.0.2
using version 1.16.0 of the Cabal library

What could be wrong here? My $PATH variable is:

$ echo $PATH
/home/user/.rvm/gems/ruby-2.2.2/bin:/home/user/.rvm/gems/ruby-2.2.2@global/bin:/home/user/.rvm/rubies/ruby-2.2.2/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/user/.rvm/bin:/home/user/.rvm/bin

and cabal is located:

$ which cabal
/usr/bin/cabal

A sudo find / -name *cabal* yielded:

I tried to install pandoc on manjaro and therefore I installed ghc and caball-install, but I got an error by executing "cabal update" $ cabal update Downloading the latest package list from hackage.haskell.org cabal: Codec.Compression.Zlib: premature end of compressed stream I also were not able to install Pandoc with help AUR.

I wanted to compile xmonad from source, so I checked out the code and ran the first command from the README. $ runhaskell Setup.lhs configure --user --prefix=$HOME Configuring xmonad-0.12... Setup.lhs: At least the following dependencies are missing: X11 >=1.5 && <1.7 Apparently haskell wants a specific version of X11. This kind of scares me, as whenever I touch video-specific items like Xorg or video drivers, I tend to completely bork my system. 1. Is it safe to install a specific newer version of X11? 2. How would I do so? Is it possible to use apt-get?
