(the 'impossible' happened) Linker error ---------------------------------+--------------------------------- Reporter: mcmayer | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.3 Keywords: ghc panic | Operating System: MacOS X Architecture: x86 | Type of failure: None/Unknown Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: ---------------------------------+--------------------------------- On Mac OS X 10.12.2 the [http://brew.sh] installation of Haskell `stack` is used (`brew install haskell-stack`). Next, the `yesod-simple` template is instantiated and built, e.g. {{{ stack new my-web yesod-simple cd my-web stack build }}} The error looks like this: {{{ ➜ my-web stack build yesod-auth-1.4.15: configure yesod-auth-1.4.15: build Progress: 1/4 -- While building package yesod-auth-1.4.15 using: /Users/mmayer/.stack/setup-exe-cache/x86_64-osx/Cabal- simple_mPHDZzAJ_1.22.5.0_ghc-7.10.3 --builddir=.stack- work/dist/x86_64-osx/Cabal-1.22.5.0 build --ghc-options " -ddump-hi -ddump-to-file" Process exited with code: ExitFailure 1 Logs have been written to: /private/tmp/my-web/.stack-work/logs/yesod- auth-1.4.15.log Configuring yesod-auth-1.4.15...
