#10726: Upgrade MingW-w64 distributions for windows -------------------------------------+------------------------------------- Reporter: Phyx- | Owner: Type: task | Status: patch Priority: high | Milestone: 7.10.3 Component: Build System | Version: 7.11 Resolution: | Keywords: Operating System: Windows | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #9218 #9014 | Differential Rev(s): Phab:D1123 #10435 | Wiki Page: | -------------------------------------+------------------------------------- Comment (by Phyx-): LogFloat seems to have a fallback method to a less accurate version depending on if FFI is used: {{{ #ifdef __USE_FFI__ foreign import ccall unsafe "math.h log1p" log1p :: Double -> Double #else -- See statistics:Statistics.Math for a more accurate Haskell -- implementation. log1p :: Double -> Double {-# INLINE [0] log1p #-} log1p x = log (1 + x) #endif }}} `__USE_FFI__` is set in the cabal file but of course won't be set using `--interactive`. Adding `-D__USE_FFI__` to the command should trigger the same error. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10726#comment:56 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
