У меня есть два файла в папке app
app/
|-- Main.hs
|-- SomeFunc2.hs
SomeFunc2.hs
просто для печати другой строки
module SomeFunc2 where
import Lib
main :: IO ()
main = putStrLn "someFunc2"
Когда я определяю несколько исполняемых файлов в package.yaml
вот так
executables:
multiexes-exe:
main: Main.hs
source-dirs: app
ghc-options:
- -threaded
- -rtsopts
- -with-rtsopts=-N
dependencies:
- multiexes
somefunc2-exe:
main: SomeFunc2.hs
source-dirs: app
ghc-options:
- -threaded
- -rtsopts
- -with-rtsopts=-N
dependencies:
- multiexes
Я получил ошибку:
