如何使用GCC7.2在Ubuntu17.10上构建gem5，处理C+中的问题+；汇编

我在按照官方文件的指示构建gem5时遇到了很多问题

以下是我使用过的命令：

git clone https://gem5.googlesource.com/public/gem5
cd gem5
python2 `which scons` build/MIPS/gem5.opt

这将导致此输出：

scons: Reading SConscript files ...
Warning: Your compiler doesn't support incremental linking and lto at the same time, so lto is being disabled. To force lto on anyway, use the --force-lto option. That will disable partial linking.

我试着加上

读到gcc7在头文件方面比以前的版本宽松得多，我不确定这是否有帮助，因为它只是造成了一个不同的问题：
