Re: [Haskell-cafe] "build depends:" in a .cabal file

thanks Henning. In any case, thanks to pushing I got Cabal installed. Regards, Vasili On Wed, Aug 20, 2008 at 3:04 AM, Henning Thielemann < lemming@henning-thielemann.de> wrote:

If by "faulting in" you mean downloading and installing missing

This is exactly by "faulting in" .. an analogy ...

Installing cabal-install seems to be a chicken and egg problem if enough packages are not already installed ... if not enough then one (me) can die of a thousand paper cuts bootstrapping packages up to where cabal-install can be installed. I am running Ubuntu Linux. Cabl-install is written in Haskell? If so, is there a pre-compiled Cabal-install that I can just install with all dependencies (packages) including. I also want to install HaskellDB painlessly ;^) ??

In my experience, with recent GHC there are only 3 packages needed to install cabal-install and it's pretty painless. You need zlib, HTTP and something else that I can't recall off the top of my head (but it tells you).

I believe it's filepath. Actually, installing all of those packages is not so easy, because for installation of zlib you need zlib headers (zlib-devel package) and Cabal can't tell you! I think, cabal-install should be shipped in binary form, too, because compiling it manually is no fun. However, once cabal-install runs you won't like to miss it anymore.
