无法编译内核:错误,内核不支持 PIC 模式

无法编译内核:错误,内核不支持 PIC 模式

我在重新编译内核时遇到问题。下载源码包,解压并运行

fakeroot make-kpkg kernel_image  

导致我犯了错误

               [...]

  CHK     include/generated/utsrelease.h
  UPD     include/generated/utsrelease.h
  CHK     include/generated/package.h
  UPD     include/generated/package.h
  CC      kernel/bounds.s
kernel/bounds.c:1:0: error: code model kernel does not support PIC mode

该问题可以通过更改使用 获得的内核配置来解决make menuconfig

如何消除此错误并成功编译

您可以尝试以下补丁:

diff --git a/Makefile b/Makefile
