Cabal upgrade


Just a few notes about the defected cabal-install program in the latest Haskell latform, although it seems to be older than the latest release. So why spending two hours trying to solve this infamous cabal: Codec.Compression.Zlib: incorrect header check? Because, I just want to try pandoc :-)

Ok, I must admit it was not so hard to get things working, after googling a little bit and finding THE correct solution (among a lot of useless threads) — in fact, I spent two hours on that bug, more than two third of it being devoted to reading all those threads and tweaking my current install. Then, I found it: You just need to upgrade to the latest version of cabal (1.10) and cabal-install (which are probably patched). They can be found from the Darcs repository (yes, of course it needs a working darcs, that cannot compile from source unless you already have a working cabal-install program because of the many dependencies, so I choose an x86-64 binary from The main problem stands from the package format which is not a tar.gz file as expected.

$ darcs get
$ darcs get
$ cd cabal-1.10/
$ ghc —make Setup
$ ./Setup configure —user
$ ./Setup build
$ ./Setup install
$ cd ../cabal-install/
$ chmod +x
$ ./

Note that for cabal-install the instructions resume to a single command! Once everything is finihed, you can just update your package list using cabal update at the command line.

So let’s go now:

$ cabal install pandoc -fhighlighting

At the end, if everything is working properly, you shoud see something like:

$ pandoc —version
pandoc 1.6

Ok, well I already have Asciidoc, Markdown, and rst installed on my system. I just have to figure out what pandoc will add to these already brillant strutured texting programs.
