#3242: ghci: can't load .so/.DLL for: m (addDLL: could not load DLL) ---------------------------------------+--------------------------- Reporter: jeffz1 | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.10.1 Component: GHCi | Version: 7.4.1 Resolution: | Keywords: Operating System: Windows | Architecture: x86 Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: 3658 Blocking: | Related Tickets: #7097 Differential Revisions: | ---------------------------------------+--------------------------- Comment (by dkwright): Happening for me with 2014.2.0.0 as well. Loading this code (stripped down from something more practical), example.hs, in ghci and typing {{{main}}}, gives the error: {{{ module Main where import Criterion.Main main :: IO() main = putStrLn "example" }}} Without the import of Criterion.Main, no error. It looks like it's a dependency on ieee754 from Criterion.Main that does it. Error: {{{ SNIP Loading package ansi-wl-pprint-0.6.7.1 ... linking ... done.
