Я пытался изменить проект, чтобы он также предоставил библиотеку (ранее это был просто исполняемый файл).
Единственное изменение было (в пакете hpack package.yaml):
+library:
+ source-dirs: src
+ exposed-modules:
+ - CYAva
Однако теперь при запуске stack build я вижу вывод:
2018-12-31 16:32:06.406901: [warn] Failed to load interface for `Main'
2018-12-31 16:32:06.407023: [warn] no unit id matching `main' was found
