编译 Linux 内核 3.8.0 时出错

Question

我正在尝试在安装了 Lubuntu 的虚拟机上编译 Linux 内核，但出现以下错误：

 In file included from ubuntu/aufs/aufs.h:45:0,
         from ubuntu/aufs/module.c:25:ubuntu/aufs/file.h:
 In function ‘au_vm_prfile_set’:ubuntu/aufs/file.h:289:5: error:

 make[3]: *** [ubuntu/aufs/module.o]Error 1
 make[2]: *** [ubuntu/aufs] Error 2
 make[1]: *** [ubuntu] Error 2

Answer 1

这是一个错误，你需要申请aufs3.12 mmap 补丁添加 ”虚拟机配置文件“：
