Compile error for Linux kernel 4.10.8 targeting ARM

I'm trying to cross compile the Linux kernel 4.10.8 for arm, but get this error:

      CC [M]  drivers/vhost/vhost.o

  _compiletime_assert(condition, msg, __compiletime_assert_, __LINE__)enter

Any idea how to solve this? I dont know what this module is used for, so I dont know if I actually need to compile it, but I cant find where in menuconfig to disable this module?

Solution

  • This module (CONFIG_VHOST) usually requires when you need virtualization support. If you don't require it disable it in the make menuconfig.

    If you don't need virtualization, you can ignore it and proceed your build.
