原因

要用**32**位编译

解决方法

查找所有Makefile文件

find ./ -name Makefile

image-20210913231709658

修改所有Makefile文件

  • 将**AS =as添加--32变成AS =as --32**;
  • 将**CC的-mcpu修改为-march**;
  • 在**CFLAGS后添加-m32**;

image-20210913224531952

修改为：

  7 AS86    =as86 -0 -a
  8 LD86    =ld86 -0
  9
 10 AS  =as --32
 11 LD  =ld
 12 LDFLAGS =-m elf_i386 -Ttext 0 -e startup_32
 13 CC  =gcc -march=i386 $(RAMDISK)
 14 CFLAGS  =-Wall -m32 -O2 -fomit-frame-pointer
 15
 16 CPP =cpp -nostdinc -Iinclude

static declaration of ‘fork’ follows non-static declaration

解决方法

修改init/main.c文件：删除static

image-20210913225243596

修改后：

 23 inline _syscall0(int,fork)
 24 inline _syscall0(int,pause)
 25 inline _syscall1(int,setup,void *,BIOS)
 26 inline _syscall0(int,sync)

解决方法
