Weird import cycle when using plugins
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.
