#12204: Weird import cycle when using plugins -------------------------------------+------------------------------------- Reporter: osa1 | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Here's a demo: {{{ $ ghc Plugin.hs [1 of 1] Compiling Plugin ( Plugin.hs, Plugin.o ) $ ghc Main.hs [1 of 1] Compiling Main ( Main.hs, Main.o ) Linking Main ... $ rm Main.hi Main.o $ ghc Main.hs -fplugin=Plugin Module imports form a cycle: module ‘Plugin’ (./Plugin.hs) imports itself $ cat Plugin.hs module Plugin (plugin) where plugin = undefined $ cat Main.hs module Main (main) where main :: IO () main = return () }}} Tried with 8.0.1, HEAD. I don't know why installing plugins using Cabal works but this doesn't. I can't add plugin tests because of this. I can try fixing this myself if someone points me to the right direction -- I have no idea which part of the compiler could be doing this. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12204 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
