#9176: GHC not generating dyn_hi files -----------------------------+---------------------------------- Reporter: heatsink | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.9 Resolution: | Keywords: dynamic Operating System: MacOS X | Architecture: x86_64 (amd64) Type of failure: Other | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -----------------------------+---------------------------------- Comment (by heatsink): The dyn_hi file goes missing because GHC detects a bad module interface hash and disables dynamic-too. It's disabled in `findAndReadIface` by assigning False to `canGenerateDynamicToo`. That flag stops `hscWriteIface` from writing a dyn_hi file. GHC will print diagnostic messages if it's run with `-ddump-if-trace`, so you can see this happening. IMO, this condition should be an error because GHC does not generate the file it was told to generate. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9176#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
