Bootstrapping cabal

12 03 2009

Often I have to install cabal onto a machine where I just have GHC 6.8.2 running. I’ve found the following little script quite practical to install the basics.  Once you have that installed, it is very easy to install other haskell packages with cabal.

  rm -rf $name-$version

FYI, the ‘cabal-install’ tarball on hackage includes a script ‘bootstrap.sh’ which does much the same as this (but seems to get by installing fewer packages).

doesn’t bootstrap.sh (bundled with cabal-installed) do exactly this?

I have not looked at the code of bootstrap.sh, but I can say that at the time, bootstrap.sh did not work for me while this did.
