[fendor]

Can you please do the same in debug mode, e.g. invoking hie -d, and link the logs here again? I will try the project, too.

[fendor]

Found the problem:
In the generated *.cabal file, there is no exposed module Two, for some reason.
If you open the src/Lib.hs everything works as expected for me.
It makes sense, actually. The source directory is src. Within that source directory, there is another source directory exercises which is a source directory itself.

[fendor]

As a short explanation, in Haskell you have to tell the build system exactly which modules are exposed, e.g. should be build.
In your project, I see multiple problems. You are writing a library within another library, e.g. src is source directory for a library and src/exercises is another. Easiest solution is to rename it to src/Exercises and changing the module header to:

module Exercises.Two where
...

By the way, haskell can not work module names that start with a number, e.g. the modules 1.hs and 2.hs wont fly. Also, the name of the file and module must coincide, and in the file 1.hs the module header is:

module ChapterOne where

therefore, that file should be named ChapterOne.hs.

The app folder has the identical problem as your library component. To solve this, either move the files in chapters and exercises into their own executable, or rename the folder and module structure.

Ah, thanks. My mistake.
