Question

我正在尝试在gem5中运行CPU2006，因此我下载了gem5并执行以下操作： 1：安装所需的依赖项：

>>sudo apt install build-essential git m4 scons zlib1g zlib1g-dev libprotobuf-dev protobuf-compiler libprotoc-dev libgoogle-perftools-dev python-dev python

2：下载gem5来源：

>>git clone https://gem5.googlesource.com/public/gem5

3：构建X86系统：

>>scons build/X86/gem5.opt

运行第三步期间，刚发生错误。
