#12395: Misleading GHCi errors when package is installed -------------------------------------+------------------------------------- Reporter: crockeea | Owner: Type: bug | Status: new Priority: high | Milestone: Component: GHCi | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect | Unknown/Multiple warning at compile-time | Test Case: Blocked By: | Blocking: Related Tickets: #11536 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by crockeea): @ezyang The attached example demonstrates the problem: {{{
stack test b <completes successfully>
stack exec ghci -- b/Main.hs b/Main.hs:6:14: error: Ambiguous occurrence ‘str’ It could refer to either ‘A.str’, imported from ‘A’ at b/Main.hs:2:1-8 (and originally defined at a/A.hs:7:1-3) or ‘B.str’, imported from ‘B’ at b/Main.hs:3:1-8 (and originally defined in ‘A’) Failed, modules loaded: A. }}}
The issue may be related to my .ghci file: I have `:set -ia`, but do not give a path to `b`. If I give paths to `a` and `b`, or neither, it appears to compile fine.
