#16273: Hadrian turns on `-Wno-unused-imports` for text when using integer-simple -------------------------------------+------------------------------------- Reporter: mpickering | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Build System | Version: 8.6.3 (Hadrian) | Keywords: newcomer | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- In `Settings.Warnings`, hadrian turns on `-Wno-unused-imports` for the `text` package when building with `integer-simple`. It would be good to fix `text` so we can remove this special case. 1. Build GHC with `integer-simple` and `-Werror` 2. Remove the special case for `text` in `Settings.Warnings`. 3. Fix the warnings in `text` appropriately so the build finishes. 4. Push the fix upstream and then update the submodule. This could also be debugged without having to build ghc by downloading an [https://gitlab.haskell.org/ghc/ghc/-/jobs/artifacts/master/download?job =validate-x86_64-linux-deb9-integer-simple integer-simple bindist].
