#9282: GHCi ignores .dyn_hi files ----------------------------------+------------------------------------- Reporter: mietek | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 7.8.2 Keywords: | Operating System: Unknown/Multiple Architecture: x86_64 (amd64) | Type of failure: Other Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ----------------------------------+------------------------------------- With both `.o` and `.dyn_o` object files available, GHCi 7.8.2 ignores the dynamic object files. {{{ $ cat >Foo.hs <<EOF module Foo where foo :: IO () foo = print "Foo" EOF }}} {{{ $ ghc -Wall -c -dynamic-too -o Foo.o Foo.hs }}} {{{ $ ghci GHCi, version 7.8.2: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done.

:l Foo [1 of 1] Compiling Foo ( Foo.hs, interpreted ) Ok, modules loaded: Foo.
}}} As '''rwbarton''' mentioned on IRC, the reason becomes apparent with `ghci -ddump-if-trace` {{{ FYI: cannot read old interface file: mismatched interface file ways (wanted "dyn", got "") }}} This happens both on OS X and Linux. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/9282> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
