#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 dreixel): I hit this problem too with `criterion` on Windows. `criterion` depends on `hastache`, which depends on `ieee754` without any version bounds. `ieee754-0.7.4` is good, `ieee754-0.7.3` isn't. So I fixed it with the following sequence of commands: {{{ ghc-pkg unregister criterion-1.0.1.0 ghc-pkg unregister hastache-0.6.0 ghc-pkg unregister ieee754-0.7.3 cabal install criterion --constraint="ieee754-0.7.4" }}} Hopefully others can do something similar to this. Also, package authors should update their packages to require `ieee754 >= 0.7.4`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/3242#comment:31 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
