ubuntu打实时补丁，编译内核时报错

Question

ubuntu20.05打preempt-rt实时补丁，执行sufo make modules_intall -j16后报错安装了binutils后，依旧报错，请问怎么解决

Answer 1

binutils安装的是32位的？

config X86_X32
bool "x32 ABI for 64-bit mode"
depends on X86_64
---help---
Include code to run binaries for the x32 native 32-bit ABI
for 64-bit processors. An x32 process gets access to the
full 64-bit register file and wide data path while leaving
pointers at 32 bits for smaller memory footprint.

  You will need a recent binutils (2.22 or later) with
  elf32_x86_64 support enabled to compile a kernel with this
  option set.
