#11327: GHC doesn't create dyn_o-boot files -------------------------------------+------------------------------------- Reporter: ezyang | Owner: Type: bug | Status: new Priority: low | Milestone: Component: Compiler | Version: 7.11 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Take any set of modules with a loop broken by an hs-boot, and run `ghc --make -dynamic-too` on it. Suppose A.hs imports B.hs, which source imports A.hs-boot; then compiling these you will get `A.{hi,o,dyn_hi,dyn_o}`, `B.{hi,o,dyn_hi,dyn_o}`, and ONLY `A.{hi- boot,o-boot,dyn_hi-boot}`: `A.dyn_o-boot` is missing. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/11327> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
