#15908: Hadrian: Spurious build failure on fresh build -------------------------------------+------------------------------------- Reporter: heisenbug | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.8.1 Component: Build System | Version: 8.7 (Hadrian) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Building GHC | Unknown/Multiple failed | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by heisenbug): I see. You should be able to reproduce the `GHC.Prim` issue by `git reset --hard 36fcf9edee~1` (be sure to check `git status` first, and save all your work). Now zap your `_build` and redo it. Then `git reset --hard 36fcf9edee` and do an incremental build. This should result in the same error. The reason is probably that when new primitives are introduced, some generators (`genPrim` or such?) need to run. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15908#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
