#7958: 'Cannot continue after interface file error' during compilation --------------------------------------+------------------------------------- Reporter: jstolarek | Owner: Type: bug | Status: new Priority: normal | Component: Compiler Version: 7.7 | Keywords: Os: Unknown/Multiple | Architecture: Unknown/Multiple Failure: GHC rejects valid program | Blockedby: Blocking: | Related: --------------------------------------+------------------------------------- I'm trying to compile [http://hackage.haskell.org/package/test-framework- hunit `test-framework-hunit-0.3.0`] library using HEAD. Running these commands: {{{ ghc Setup.lhs && \ ./Setup configure --user --enable-shared && \ ./Setup build && ./Setup install }}} gives me this error: {{{ Installing package test-framework-hunit-0.3.0 [1 of 1] Compiling Main ( Setup.lhs, Setup.o ) Linking Setup ... Configuring test-framework-hunit-0.3.0... Building test-framework-hunit-0.3.0... Preprocessing library test-framework-hunit-0.3.0...

This didn't happen on HEAD 12 days ago, so I think it must be some recent change that broke this. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7958 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
