centos7编译linux的内核源码

时间：2016-07-11 23:42:56   收藏：0   阅读：2778

昨天编译了一个linux 内核源码，遇到一些问题， 今天把我遇到的问题和解决方法分享给大家。希望可以帮助到需要的人。

1）检查是否安装了相应的包（我第一次编译的时候只安装的“Development Tools” 包，”Compatibility Libraries“和”Development and Creative Workstation“没有安装）

[root@localhost yum.repos.d]# yum groups list　　#查看包组列表
Loaded plugins: fastestmirror, langpacks
There is no installed groups file.
Maybe run: yum groups mark convert (see man yum)
Loading mirror speeds from cached hostfile
Available Environment Groups:
   Minimal Install
   Compute Node
   Infrastructure Server
   File and Print Server
   Basic Web Server
   Virtualization Host
   Server with GUI
   GNOME Desktop
   KDE Plasma Workspaces
   Development and Creative Workstation
Available Groups:
   Compatibility Libraries
   Console Internet Tools
   Development Tools
   Graphical Administration Tools
   Legacy UNIX Compatibility
   Scientific Support
   Security Tools
   Smart Card Support
   System Administration Tools
   System Management
Done

2）下载源码从https://www.kernel.org/网站下载需要编译的内核。

这里直接使用wget命令进行下载

[root@localhost yum.repos.d]# cd /root　　#切换到root目录
[root@localhost ~]# wget https://cdn.kernel.org/pub/linux/kernel/v4.x/testing/linux-4.7-rc7.tar.xz　　//使用wget下载文件

[root@localhost ~]# ls -l | grep linux　　　　#查看下载的文件
-rw-r--r--. 1 root root 90401360 Jul 10 23:41 linux-4.7-rc7.tar.xz

3）解压文件和创建符号链接文件

tar -xf linux-4.7-rc7.tar.xz  -C /usr/src/　　#解压缩到指定目录
[root@localhost ~]# ls
anaconda-ks.cfg  Documents  initial-setup-ks.cfg  Music     Public     Videos
Desktop          Downloads  linux-4.7-rc7.tar.xz  Pictures  Templates
[root@localhost ~]# cd /usr/src/　　#进入文件目录
[root@localhost src]# ls
debug  kernels  linux-4.7-rc7
[root@localhost src]# ln -sv linux-4.7-rc7/ linux　　#创建符号链接
‘linux’ -> ‘linux-4.7-rc7/’
[root@localhost src]# ls　　　　　　#查看
debug  kernels  linux  linux-4.7-rc7

4）创建.config文件

[root@localhost linux]# ls
arch   COPYING  Documentation  fs       ipc      kernel  MAINTAINERS  net             samples   sound  virt
block  CREDITS  drivers        include  Kbuild   lib     Makefile     README          scripts   tools
certs  crypto   firmware       init     Kconfig  linux   mm           REPORTING-BUGS  security  usr
[root@localhost linux]# make menuconfig
  HOSTCC  scripts/basic/fixdep
  HOSTCC  scripts/kconfig/mconf.o
In file included from scripts/kconfig/mconf.c:23:0:
scripts/kconfig/lxdialog/dialog.h:38:20: fatal error: curses.h: No such file or directory
 #include CURSES_LOC
                    ^
compilation terminated.
make[1]: *** [scripts/kconfig/mconf.o] Error 1
make: *** [menuconfig] Error 2

这里报错误了。 提示curses.h 这个文件找不到。 

[root@localhost linux]# yum search curses　　　　#从yum源查找curses相关的包 ， 配置本地yum源看我上篇博客。

Complete!

再次make menuconfig这个命令后，会出现如下的字符界面，我们就可以在这个界面上对内核进行配置。我们这里是第二次使用make menuconfig了，需要先运行：make mrproper来清除以前的配置，回到默认配置，然后再运行：make menuconfig生成.config文件 通过这个工具可以设置内核配置参数。

4）执行make 命令

上面的报错了， 才发现原来的编译环境的包没有安装好。

执行下面命令安装包

[root@localhost linux]# yum groups list
Loaded plugins: fastestmirror, langpacks
There is no installed groups file.
Maybe run: yum groups mark convert (see man yum)
Loading mirror speeds from cached hostfile
Available Environment Groups:
   Minimal Install
   Compute Node
   Infrastructure Server
   File and Print Server
   Basic Web Server
   Virtualization Host
   Server with GUI
   GNOME Desktop
   KDE Plasma Workspaces
   Development and Creative Workstation
Available Groups:
   Compatibility Libraries
   Console Internet Tools
   Development Tools
   Graphical Administration Tools
   Legacy UNIX Compatibility
   Scientific Support
   Security Tools
   Smart Card Support
   System Administration Tools
   System Management
Done
[root@localhost linux]#yum groups  install  "Development and Creative Workstation" "Compatibility Libraries" -y

 

5）执行 make clean 和make 

[root@localhost linux]# make clean 
  CLEAN   .
  CLEAN   arch/x86/purgatory
  CLEAN   arch/x86/tools
  CLEAN   .tmp_versions
[root@localhost linux]# make

6） 执行 make modules_install

7) 执行make install 

[root@localhost linux]# make modules_install 
[root@localhost linux]# make install

8)重新电脑选择新编译好的linux吧。
