3、 Trackback一般来说，如果不是自己编译kernel，那么更新头文件是比较容易的事情，在Ubuntu/Fedora等操作系统上，可以直接安装相应的linux-headers软件包，下面就演示了在Ubuntu上安装内核头文件的过程。ViewCode BASH123456789master@jay-intel:~/workspace/c-study$uname-r3.2.0-33-genericmaster@jay-intel:~/workspace/c-study

5、inuxkernel并用它启动了系统，然后为了让本地程序基于当前kernel的headers来编译，就需要自己手动更新内核的头文件了。手动更新linuxheaders的步骤如下：1.在Linuxkernel目录中，执行“makeheaders_install”命令，将headers安装到当前目录的usr/include/下面。2.将以前的headers备份：包括/usr/include/目录下的asm，asm-generic,linux等目录。3.将刚才生成的当前编译内核目录下的usr/include/中的asm，asm-generic,linux等目录复制到/usr/i

6、nclude/目录下即可。（当然如果还需要更新其他的目录的头文件，也都可以一起复制过去。）操作演示如下：ViewCode BASH1234567891011121314151617[root@jay-linuxkvm.git]#makeheaders_installCHKinclude/generated/uapi/linux/version.hWRAParch/x86/include/generated/asm/clkdev.hSYSHDRarch/x86/syscalls/../include/generated/uapi/asm/unistd_32.hSYSHDRa
