Linux内核4.10.8目标ARM编译错误

Question

我试图交叉编译arm的Linux内核4.10.8，但是得到了以下错误：

      CC [M]  drivers/vhost/vhost.o
In file included from ./include/uapi/linux/stddef.h:1:0,
                 from ./include/linux/stddef.h:4,

                 from ./include/linux/eventfd.h:11,
                 from drivers/vhost/vhost.c:14:
drivers/vhost/vhost.c: In function ‘vhost_vring_ioctl’:
./include/linux/compiler.h:518:38: error: call to ‘__compiletime_assert_1357’ declared with attribute error: BUILD_BUG_ON failed: __alignof__ *vq->avail > VRING_AVAIL_ALIGN_SIZE
  _compiletime_assert(condition, msg, __compiletime_assert_, __LINE__)enter 

知道怎么解决这个问题吗？我不知道这个模块是用来做什么的，所以我不知道我是否真的需要编译它，但是我无法在menuconfig中找到禁用这个模块的位置。

Answer 1

当您需要CONFIG_VHOST支持时，通常需要这个模块( virtualization )。如果不需要，请在make menuconfig中禁用它。

如果您不需要虚拟化，您可以忽略它并继续构建。
