[英]Problems while integrating HUnit with Cabal
The command cabal install
works fine, as does cabal configure --enable-tests
. cabal install
命令运行良好, cabal configure --enable-tests
。 However, when I run cabal build -j
it does not compile: 但是,当我运行cabal build -j
它不会编译:

This is the structure of the source directory: 这是源目录的结构:
src
├── Main.hs
├── Moodle
│ ├── Parser.hs
│ ├── Translator.hs
│ └── Types.hs
└── Test
└── Moodle.hs
And this is my Cabal file (relevant lines only): 这是我的Cabal文件(仅相关行):

I followed the steps in the cabal-test-hunit README . 我按照cabal-test-hunit README中的步骤进行操作 。 I also wonder, is it even necessary to declare the dependencies two times?! 我也想知道,是否有必要两次声明依赖项? It's not very DRY. 它不是很干。
EDIT : It seems that it cannot find my modules. 编辑 :似乎找不到我的模块。 However, if I add MoodleLatex
to build-depends
I run into another error: 但是,如果我将MoodleLatex
添加到build-depends
项中, MoodleLatex
遇到另一个错误:
Building MoodleLatex-0.1.0.0...
Preprocessing executable 'moddlelat' for MoodleLatex-0.1.0.0...
Preprocessing test suite 'Moodle-Tests' for MoodleLatex-0.1.0.0...

You should add the additional modules to the other-modules
field. 您应该将其他模块添加到other-modules
字段。 If you build with Stack, it should give you a warning about which modules need to be specified. 如果您使用Stack进行构建,它会警告您需要指定哪些模块。
