以上就是错误信息，我的机器是amd5000+,难道LFS不能在64位的cpu中安装吗？

没天理啊！！现在的6.4的宿主系统必须是32位的，有那位在64机子上面安装成功的吗？

RTL

懷疑是 lz 做 x86_64 的 lfs 時做了 這一步
echo "CFLAGS += -march=i486 -mtune=native" > configparms

-march=i486  的時代還沒有 x86_64 而lz 又用了這個

x86_64 省去 echo "CFLAGS += -march=i486 -mtune=native" > configparms

楼上的，你在x86_64位机子里安装成功了吗？
官方的lfs6.4怎么表明不支持64位！
