I've made a start on sanitising the Windows building instructions, and generally reoganising the Windows-related stuff in the wiki. Basicalliy my plan is to: - Simplify the instructions. In lots of places we have stuff like "if you get the following bizarre error message ... then do this ...". I'd rather have a set of simple instructions that just work, with a separate (searchable) page for troubleshooting advice. So now we have http://hackage.haskell.org/trac/ghc/wiki/Building/Troubleshooting which is just a list of error messages and solutions, collected from various other places in the docs. If you encounter an error that isn't listed on that page, please add it (guidelines for adding stuff are at the top). - Merge the Windows-specific instructions with the rest of the docs, so we can avoid repetition. So now the instructions for how to set up your Windows system for building GHC are on the main "prerequisites" page: http://hackage.haskell.org/trac/ghc/wiki/Building/Prerequisites - I've uploaded a set of build tools that work (just MSYS for now) to haskell.org, and linked them from the wiki. This morning I started from a fresh Vista system, installed these tools, and managed to do a complete validate of the GHC HEAD, with 1 test failure. What we still need to do: - Expand the instructions to include Cygwin. I've linked to the existing Cygwin instructions for now, but I think they need simplifying. - Add more common failures and troubleshooting tips. - Merge in contrib docs, e.g. http://hackage.haskell.org/trac/ghc/wiki/ProblemsCompilingGhc I'd be grateful for any help with this - just edit away!
