Intero doesn't find Paths-module when using cabal data files

Question

When I use the data-files feature of cabal, it generates a Paths_pkgname.hs module that lives in the dist/ folder.

However, intero is unable to find this file (or generate it on its own), and I can't find any means to pass an option to hint at its position.

Note: Somewhere else (on SO?) I picked up the trick when using ghci to make a dummy only-for-ghci/Paths_.hs that is only brought into scope through :set -ionly-for-ghci being set in .ghci. This won't apply for intero though, as its invocation in intero.el specificcally instructs it to ignore the .ghci file.

Answer 1

I was only building my project using cabal and nix. It turns out that because Intero is stack-centric, building the project with stack build does indeed put a Paths_.. module in a place where Intero searches.
