@hvr: The fact that Hadrian currently depends on the in-tree Cabal library has proven to be both slow and fragile. Neil and I have recently been thinking that we should revert to depending on a stable release of Cabal instead. Pros: * This will make Hadrian faster to build if the (stable) Cabal library is shared with other projects on the same machine. * We don't need to adapt/rebuild Hadrian every time the in-tree Cabal library is changed. We will upgrade to a new Cabal version only when need be. * This will hopefully allow us to avoid issues like the one described in this ticket. Cons: * We will not be able to parse GHC's `.cabal` files if they use bleeding- edge features of Cabal. And arguably, they shouldn't. Any thoughts on this? I could spawn this into a separate ticket. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16259#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
