What is Paths_app?

[chrissound]

I've just tried to use another local package as a dependency with stack but it seems hpack generates a Paths_app which results in an error of:

Loading stack ghci --ghci-options='-fdiagnostics-color=always' ...
The same package name is used in multiple local packages

app used in:
- PLOther (PLFilePath "/home/chris/Haskell/NiobiumCoconut")
- PLOther (PLFilePath ".")

What is this module doing? Is it possible to exclude to resolve the above error?

Hey! Thanks for reporting this!

hpack generates a Paths_app which results in an error of

I don't see a reference to Paths_app in that error message.

What is this module doing? Is it possible to exclude to resolve the above error?

Paths_* is generated by Cabal (first google hit on the topic http://neilmitchell.blogspot.com/2008/02/adding-data-files-using-cabal.html).

You can prevent hpack from including Paths_* in your package description by specifying other-modules manually (in the simplest case just other-modules: []).

See also #303.

Apologies this does not seem to be related to Paths_app or hpack, I assumed the PLOther related to Paths_app - but just seems like verbose error. Thank you for your response! :)

To anyone else that has stumbled upon this:
It's to do with the package name (in my case app) being used in both of the packages.
