源码下载

问题一：Windows 的ubuntu子系统更滑阿里源 ，子系统版本为Ubuntu 24.04.2 LTS 修改/etc/apt/sources.list

lsb_release -a  # 确认输出为24.04 LTS (noble)
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
sudo vi /etc/apt/sources.list

deb https://mirrors.aliyun.com/ubuntu/ noble main restricted universe multiverse
deb https://mirrors.aliyun.com/ubuntu/ noble-security main restricted universe multiverse
deb https://mirrors.aliyun.com/ubuntu/ noble-updates main restricted universe multiverse
deb https://mirrors.aliyun.com/ubuntu/ noble-backports main restricted universe multiverse
# 预发布源（不建议启用）
# deb https://mirrors.aliyun.com/ubuntu/ noble-proposed main restricted universe multiverse

sudo apt clean
sudo rm -rf /var/lib/apt/lists/*
sudo apt update && sudo apt upgrade -y

问题二：Linux 5.10 LTS 下载 从阿里源下载

# 下载5.10系列最新稳定版（示例）
wget https://mirrors.aliyun.com/linux-kernel/v5.x/linux-5.10.200.tar.xz

tar -xvf linux-5.10.xxx.tar.xz
cd linux-5.10.xxx

编译过程中遇到的问题

一、make x86_64_defconfig失败

解决办法：

apt install make
apt install make-guile

二、再次make仍然失败

oot@DESKTOP-UU5RN4I:/home/kevin/linux_kernel/linux-5.10.200#  make  x86_64_defconfig
  HOSTCC  scripts/basic/fixdep
  HOSTCC  scripts/kconfig/conf.o
  HOSTCC  scripts/kconfig/confdata.o
  HOSTCC  scripts/kconfig/expr.o
  LEX     scripts/kconfig/lexer.lex.c
/bin/sh: 1: flex: not found
make[1]: *** [scripts/Makefile.host:9: scripts/kconfig/lexer.lex.c] Error 127
make: *** [Makefile:615: x86_64_defconfig] Error 2

解决办法：

sudo apt install flex bison
sudo apt install build-essential libncurses-dev libssl-dev dwarves

上述两个问题解决后make config成功

三、编译是报错

error: Cannot generate ORC metadata for CONFIG_UNWINDER_ORC=y, please install libelf-dev, libelf-devel or elfutils-libelf-devel
make: *** [Makefile:1264: prepare-objtool] Error 1

解决办法：

sudo apt install libelf-dev libssl-dev

最后清理后重新编译成功

make clean
make x86_64_defconfig
make -j$(nproc)
