#haskell folk: how do I verify that my package can be built with bytestring 0.12? There is no GHC releases that bundle that version yet. Is there some flag that could tell it to use a version from Hackage rather than the one included into the GHC distribution?
@minoru Just specify the version in the cabal file of the target package and then call cabal to install them deps?
@L29Ah Why do I have to install them? Can't I make Cabal pull it from Hackage like every other dependency?
I don't want to pollute my system with packages installed via Cabal. Although I think Cabal now has some sort of a sandbox, perhaps I should look into that.
@L29Ah Oops! I was specifying
--constrain 'bytestring == 1.12.0.2', which failed because 1.12.0.2 doesn't exist. The error message looked just like the one I get if a dependency can't be satisfied.Thanks :)
