我正在尝试为 Raspberry PI 2 构建自己的 lfs 系统。
作为其中的一部分，我尝试在 Raspberry PI 2 上编译 gcc，并以 raspbian 作为基本操作系统。
我可以使用 lfs 开发版本上的说明构建 binutils。但是在编译 gcc 时出现以下错误

我尝试通过查看 expr.c 文件来追踪错误原因，但找不到问题。我已将“/tmp/ccAUc9Pu.out”上传到 http://turl.ca/dcfansr
有人可以帮助我如何调试问题的确切原因
最佳答案
通过运行版本检查 http://www.linuxfromscratch.org/lfs/view/stable-systemd/prologue/hostreqs.html 检查所有系统要求是否已安装后，我遇到了同样的问题并重新启动系统后它就可以工作了。
