linux1.0--1.ubuntu14.04下编译linux1.0

环境: Ubuntu 14.04.2 LTS 64位

GCC: gcc (Ubuntu 4.8.2-19ubuntu1) 4.8.2

1. 编译流程需要三步
下载linux1.0.tar.gz然后解压至任意目录
cong@msi:/work/qemu/x86/linux$ make config
cong@msi:/work/qemu/x86/linux$ make dep
cong@msi:/work/qemu/x86/linux$ make zImage



2. Makefile修改
TOPDIR  := $(shell if [ "$$PWD" != "" ]; then echo $$PWD; else pwd; fi)

CC =gcc -D__KERNEL__ -I$(TOPDIR)/include

serial.c:538:8: error: macro names must be identifiers
 #ifdef 0
cong@msi:/work/qemu/x86/linux$ vi drivers/char/serial.c
将#ifdef 0 -->#if 0


buffer.c:108:8: error: macro names must be identifiers
 #ifdef 0 /* Disable bad-block debugging code */
cong@msi:/work/qemu/x86/linux$ vi fs/buffer.c
将#ifdef 0 -->#if 0

sched.c:41:25: error: conflicting type qualifiers for 'xtime'
/work/qemu/x86/linux/sched.h:308:23: note: previous declaration of 'xtime' was here
将include/linux/sched.h中
//extern struct timeval xtime;
extern volatile struct timeval xtime;

cong@msi:/work/qemu/x86/linux$ as -c -o boot/head.o boot/head.s
boot/head.S: Assembler messages:
boot/head.S:64: Error: invalid instruction suffix for `push'
boot/head.S:65: Error: invalid instruction suffix for `popf'
boot/head.S:99: Error: invalid instruction suffix for `pushf
修改Makefile:
.s.o:
   $(AS) $(ASFLAGS) -c -o $*.o $<

gcc -D__KERNEL__ -I/work/qemu/x86/linux/include -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -pipe -m486 -c -o init/main.o init/main.c
gcc: error: unrecognized command line option ‘-m486’
修改Makefile:

还有很多有时间再整理 




3.现在己经可以编译通过了，但是运行时还有点问题，先把修改的diff文件如下
change.rar(下载后改名为change.tar.gz)
