Hi, we recently added the latest version of cabal-install into the lts:7 project [1], but the tool won't compile since it depends on Cabal >=1.24.1 && <1.25, which we don't have since GHC 8.0.1 ships Cabal 1.24.0.0 as a core library. Now, I see two options to remedy this issue: 1) We patch the GHC 8.0.1 build to contain the latest Cabal release or 2) we add Cabal-1.24.1.0 as an a additional library into the OBS project. Option (1) is probably the easier solution of the two, but patching the GHC build feels dangerous to me, because we'll venture into a territory that's not supported by the GHC developers. Also, I am not aware of any other distribution going that route. Option (2) is perfectly safe, but it's hard'ish to pull off because we cannot just add a second version of "Cabal" to our project (and certainly not to Factory). So we'd probably have to call that library "Cabal_1_24_1_0" and add appropriate "provides" and "conflicts" attributes. I'm not quite sure how all this works since I haven't done such a thing before. Figuring this out might be worthwhile, though, because in the long run we'll need multiple versions of Haskell libraries available if we want to ship recent versions of important tools. Right now, "stack" is blocked by version conflicts, for instance, that we cannot resolve without having multiple library versions. Anyhow, is anyone aware of a third option that I missed? Does anyone have an opinion in this matter?
