Thanks largely to Ian Lynagh, GHC now has a BuildBot infrastructure to automate nightly builds on multiple platforms. This replaces the old set of shell scripts that we used to run nightly builds; now adding new clients to the setup is relatively easy, instructions are here: http://hackage.haskell.org/trac/ghc/wiki/BuildBot So far we have various Windows builds running, and I'll be moving over the existing Linux nightly builds in due course. If you have a spare machine or a machine that is idle overnight, and you'd like to use it to run automated GHC builds, then please take a look at the above page for how to get started. We especially need platforms that we don't use regularly (i.e. not Windows or Linux/x86/x86_64). Cheers, Simon
