Настройка стека Haskell — Не удается распознать программу CPP

Я следую за курсом Udemy Haskell, который в какой-то момент показывает, что я загружаю Haskell, используя опцию Stack. Я настроил свой $ PATH и запустил установку стека, когда столкнулся с проблемой.

configure: WARNING: configure can't recognize your CPP program, you may need to set --with-hs-cpp-flags=FLAGS explicitly
configure: error: in `/Users/Dylan/.stack/programs/x86_64-osx/ghc-8.0.2.temp/ghc-8.0.2':
configure: error: C compiler cannot create executables

Я смотрел в .stack/programs/x86_64-osx/ghc-8.0.2.temp/ghc-8.0.2/config.log и нашел это …

Я умею читать configure: WARNING: configure can't recognize your CPP program, you may need to set --with-hs-cpp-flags=FLAGS explicitly, но я не уверен, как и где это сделать. Я нашел свой файл settings.in …

Но опять же, я не знаю, что с этим делать. Извините, если мой вопрос является базовым, но я не делал ничего подобного раньше, и то, что я нашел в Интернете, было трудно интерпретировать, как это применимо к моей ситуации.

Любая помощь будет принята с благодарностью. ��
