#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 oerjan): I suspect I just hit this bug when trying to `cabal install random-extras` from Haskell Platform 2014.2.0.0 on Windows 8.1. The dependency `random- fu` uses the `logfloat` library from Template Haskell while compiling other modules, which gives me the error message: {{{ [ 7 of 29] Compiling Data.Random.Distribution.Uniform ( src\Data\Random\Distribu tion\Uniform.hs, dist\build\Data\Random\Distribution\Uniform.o ) Loading package ghc-prim ... linking ... done. [snipped long package list] Loading package logfloat-0.12.1 ... ghc.exe: m: Den angitte modulen ble ikke fun net. <command line>: can't load .so/.DLL for: m.dll (addDLL: could not load DLL) Failed to install random-fu-0.2.6.1 cabal: Error: some packages failed to install: random-extras-0.19 depends on random-fu-0.2.6.1 which failed to install. random-fu-0.2.6.1 failed during the building phase. The exception was: ExitFailure 1 }}} `logfloat.cabal` contains precisely such an `Extra-Libraries: m` line that is used in its default configuration. And trying to use `logfloat` from (Win)GHCi gives the same kind of error message. I am able to get around this for `logfloat` by giving `--flags -useFFI`, but I still think it's a shame if this bug prevents a straightforward cabal install from working. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/3242#comment:27 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
