#8686: "cannot find normal object file" error during compilation -----------------------------------+--------------------------------------- Reporter: jstolarek | Owner: Type: bug | Status: new Priority: high | Milestone: 7.8.1 Component: Compiler | Version: 7.7 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Compile-time crash Unknown/Multiple | Test Case: Difficulty: Unknown | Blocking: Blocked By: | Related Tickets: | -----------------------------------+--------------------------------------- When I try to compile tests provided in the [http://hackage.haskell.org/package/singletons singletons] package I get the following error: {{{ Building singletons-0.9.3... Preprocessing library singletons-0.9.3... In-place registering singletons-0.9.3... Preprocessing test suite 'compile' for singletons-0.9.3...

Data/Singletons/Core.hs:1:1: cannot find normal object file ‛dist/build/compile/compile- tmp/Data/Singletons/Util.dyn_o’ while linking an interpreted expression }}} This happens on HEAD but not on 7.6.3. Steps to reproduce: 1. Download and extract singletons source code 2. In the cabal file uncomment test-suite section (which is commented out because it doesn't work) 3. `cabal configure --enable-tests && cabal build` Reproducing this requires installing packages required by singletons. I'm setting milestone to 7.8 as this is something that looks like a blocker in a stable release. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8686 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
