Я установил все зависимости (git, g ++, python, zlib, m4, protobuf, swig и pydot) и клонировал проект gem5 из "https://raw.githubusercontent.com/arm-university/arm-gem5-rsk/master/clone.sh$ bash clone.sh". И когда я пытаюсь собрать его с помощью "scons build / ARM / gem5.opt", он выдает следующие ошибки:

Мне нужно установить симулятор gem5. Как я могу их исправить?
