Elixir CRC не будет компилироваться в MAC OS

Мой проект эликсира косвенно использует crc, который имеет NIF. Они не будут компилироваться. Похоже, что связанный не видит библиотеки.

Скорее всего это проблема конфигурации. Я опубликую минимальный воспроизводимый проект, хотя

Какую библиотеку вы используете для CRC? Я предполагаю следующее: github.com/TattdCodeMonkey/crc Вы используете последнюю версию? Если вы клонируете репо и запускаете mix do deps.get, compile, это сработает? - mroach 10.07.2020

comment

Неа. Я сделал чистый, смешал deps.clean несколько раз. Как вы видели в первом посте, я использовал rm -rf deps/ _build/ && mix deps.get && mix compile. Так что выход был со свежими депсами. - Haito 10.07.2020

Вам необходимо установить библиотеки разработки erlang, где это _enif_*** объявляется семейство функций.

В Debian Linux:

через Erlang Solutions — предпочтительнее
используя репозиторий дистрибутива: sudo apt install erlang-dev

Для MacOS Erlang Solutions предоставляет только старый OTP версии 19.3, я понятия не имею, предоставляет ли brew последний OTP. Если это так, сделайте brew install erlang-r23-dev или подобное. Если это не так, вы, вероятно, в состоянии скомпилировать erlang< /а> себя.
