下载官网的最新Linux内核版本，Linux虚拟机中Ubuntu 下载速度慢，更换镜像源后使下载速度正常。这是一个.tar.xz文件，我们要先来解压它。下面是下载内核解压文件编译内核配置内核的全过程。由于我们并没有正确的写好相关配置文件，我们的内核编译是失败的。
First,we would like to download the latest Linux kernel from Linux website .It seems that we could choose some old versions with smaller size but we prefer to using the latest one firstly.
xz -d linux-5.7.tar.xz
tar -xvf linux-5.7.tar
After decompressing the file, we would like to explore it.
cd linux-5.7/
ls
Here we have met a problem after entering make menuconfig in the terminal .We can not open the Linux kernel configuration window.

make[1]: *** [scripts/kconfig/lexer.lex.c] Error 127
Makefile:588: recipe for target 'menuconfig' failed
make: *** [menuconfig] Error 2
We should compile successfully before configuring.
We have met several menu before and we are worried that we might change something important so we have not modified them.
先把问题放在这里，我们的内核配置选项特别多，我们先来学习相关内容然后再回头解决编译出错的问题。在学习之前，我们可以探索一下相应的内容。

今日写文背景音乐《悦神》
一场盛世繁华 若指尖沙 似传说的话
庙堂高墙的画 吹落的刹那
雨中红伞探白花 华服金面高楼下
一念间 桃源已成飞沙
上元灯火漫天 千山万水潋滟
白衣蹁跹 仗剑执花 天下妄言
从此他这一眼
犹记了千百年
沧海变 桑田间 而今 再相见
红莲赤焰 莫问 是鬼 还是仙
芳心只一剑如何能救万千
彼时 金枝玉叶 斜冠散发问苍天
身在无间 心亦在无间
褪去华服金面 这人间已换了多少家
红叶吹落轻纱 看落日残霞
雨中红伞探白花 华服金面高楼下
一念间 桃源已成飞沙
月夕言笑晏晏 悦神明灯三千
布衣草笠 白绫双枷 天下未言
回首梦已阑珊 众生尽皆漠然
万世千秋 不如他 一眼经年
红莲赤焰 莫问 是鬼 还是仙
芳心只一剑如何能救万千
彼时 金枝玉叶 斜冠散发问苍天
身在无间 心亦在无间
神窟千面 是爱是恨 还是怜
岁岁复年年 谁在耳边轻言
红叶苍山 方见花开满城 一念间
千灯观前 与君话桃源
