Cannot resolve text dependency with ghc-7.8 solver #396
Description
To reproduce, in an empty directory:
stack new- Switch resolver to
ghc-7.8. - Add
text-1.2.1.1toextra-deps. - Edit
new-template.cabal, addtexttobuild-depends. - Run
stack build.
This gives the following error:
$ stack build
While constructing the BuildPlan the following exceptions were encountered:
-- While attempting to add dependency,
Could not find package integer-simple in known packages
-- Failure when adding dependencies:
text: needed (-any), but couldn't resolve its dependencies
needed for package: new-template-0.1.0.0
-- Failure when adding dependencies:
integer-simple: needed (>=0.1 && <0.5), but not present in build plan
needed for package: text-1.2.1.1
My GHC is build with integer-gmp, but adding that to the extra-deps doesn't work either (the error is the same). Text switches between these with a flag, which cabal-install usually toggles automatically to find a suitable plan.
