The command cabal install works fine, as does cabal configure --enable-tests. However, when I run cabal build -j it does not compile:

This is the structure of the source directory:

And this is my Cabal file (relevant lines only):

I followed the steps in the cabal-test-hunit README. I also wonder, is it even necessary to declare the dependencies two times?! It's not very DRY.
EDIT: It seems that it cannot find my modules. However, if I add MoodleLatex to build-depends I run into another error:
Building MoodleLatex-0.1.0.0...
Preprocessing executable 'moddlelat' for MoodleLatex-0.1.0.0...

You should add the additional modules to the other-modules field. If you build with Stack, it should give you a warning about which modules need to be specified.
