Source: ghc Version: 9.4.6-1 Severity: serious Tags: ftbfs Justification: FTBFS
The current version of GHC in unstable (9.4.6-1) FTBFS when the bootstrap compiler is newer than 9.0.2. The error message is the following: ghc.mk:141: *** The make build system requires a boot compiler older than ghc-9.2. Your boot compiler is too new and cannot be used to build ghc-9.4 with make. Either boot with ghc 9.0.2 or build with hadrian. See https://www.haskell.org/ghc/blog/20220805-make-to-hadrian.html for advice on transitioning to hadrian.. Stop. We need to switch to the newer hadrian build system in order to be able to build ghc with a newer bootstrap compiler. For more information about why the make build system fails, see the upstream issue https://gitlab.haskell.org/ghc/ghc/-/issues/21188. Thanks, -- Ilias
