Question

我试图交叉编译Linux内核4.10.8 for arm，但是得到了这个错误：

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

                 from 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

知道如何解决这个问题吗？我不知道这个模块用的是什么，所以我不知道我是否真的需要编译它，但是我无法在menuconfig中找到禁用此模块的位置？

当您需要virtualization支持时，通常需要此模块（CONFIG_VHOST）。如果您不需要，请在make menuconfig中将其停用。

如果您不需要虚拟化，则可以忽略它并继续构建。
