Greetings café, There are some problems in Haddock to do with Template Haskell that I believe are being caused by Cabal. These were apparently addressed in 1.18 which came out recently. ‘Great!’, I thought. My problem is that I'm unsure how to use 1.18. I'm using GHC HEAD (well, 3 days old now) which is meant to come with Cabal 1.18 (the library) and in fact it seems to ship with it. Running ‘cabal --version’ however:
cabal-install version 1.17.0 using version 1.17.0 of the Cabal library
I'm unsure how to get it to use 1.18. I tried to build cabal-install from git but that just complains about dependencies not being possible to resolve: it depends on HTTP which depends on base <4.7 but 4.7 comes with GHC HEAD! I am baffled as to how I should go about using 1.18 and would love to hear from some people who have this up and running. -- Mateusz K.
