В настоящее время я делаю небольшой проект с намерением сделать неполную реализацию JPEG в долгосрочной перспективе. До этого я выполняю реализацию относительно более простого формата файла PNG. Ошибки, которые я получаю, следующие:

По какой -то причине я не вижу, чтобы он добавил здесь какие -либо параметры -i, я попытался добавить их в флаги сборки вручную, но это не исправляло.
