#15286: "Can't use Natural in base" when compiling GHC.Natural with -O0 -------------------------------------+------------------------------------- Reporter: alpmestan | Owner: (none) Type: bug | Status: patch Priority: normal | Milestone: Component: libraries/base | Version: 8.5 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): Phab:D4880 Wiki Page: | -------------------------------------+------------------------------------- Comment (by alpmestan): I haven't looked into the actual problem, but hsyl20's instructions from https://ghc.haskell.org/trac/ghc/ticket/15570#comment:13 seem to work, I just opened [https://github.com/snowleopard/hadrian/pull/674 hadrian#674] to get rid of those `-O0`s. This also fixes many failing tests. This doesn't answer anything about the problem though of course. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15286#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
