#11085: Relying on the existence of CallStack in 7.10 breaks bootstrappability with 7.10.1 -------------------------------------+------------------------------------- Reporter: quchen | Owner: Type: bug | Status: new Priority: normal | Milestone: 8.0.1 Component: Compiler | Version: 7.10.2 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Building GHC Unknown/Multiple | failed Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): D1472 | Wiki Page: -------------------------------------+------------------------------------- 7.10.2 added the CallStack mechanism, and GHC already relies on this while being built. Unfortunately, it is enabled with "GLASGOW_HASKELL >= 710", which also applies to GHC 7.10.1, which does not have CallStack, and fails building the stage-1 compiler because the symbol is not found. This patch makes the CPP directive more strict, requiring more than 7.10 instead of at least. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11085 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
