Cabal搭配c2hs找不到.chs模塊

Question

我正在嘗試c2hs，並且想編譯一個Cabal的共享庫的小例子來開始。

我有小集團文件test.cabal以下相關章節：

executable libtest.so 
    hs-source-dirs:  src 
    main-is:    Dummy.hs 
    other-extensions: ForeignFunctionInterface 
    build-depends:  base 
    default-language: Haskell2010 
    ghc-options:   -no-hs-main -threaded 
    build-tools:   c2hs 

然後來源。 src/Dummy.hs：

import Test 

main :: IO() 
main = return 

在文件src/Test.chs

{-# LANGUAGE ForeignFunctionInterface #-} 
import Foreign 
import Foreign.C 

module Android where 

，然後當我嘗試編譯（cabal configure && cabal build -v）我收到以下錯誤信息：

Component build order: executable 'libtest.so' 
creating dist/build 
creating dist/build/autogen 
Building test-0.1.0.0...

src/Dummy.hs -no-hs-main -threaded 

src/Dummy.hs:1:8: 
    Could not find module ‘Test’ 
Use -v to see a list of the files searched for. 

，能不能請你告訴我錯誤的原因是什麼？我錯過了什麼？

您需要將Test添加到其他模塊字段。
