根据源代码包中的readme文件及http://chfj007.blog.163.com/blog/static/173145044201191195856806/?suggestedreading&wumii文章编译成功。
下面我们开始编译内核的工作,首先将从网上下载的内核放到CentOS 6.3的 /usr/src目录下,然后执行下面的操作:
cd /usr/src
tar xzvf linux-1.0.tar.gz
cd /usr/include
mv linux linux-CentOS
mv asm asm-CentOS
ln -s
/usr/src/linux/include/linux .
ln -s /usr/src/linux/include/asm .

The linux kernel is now hopefully configured for your setup.
Check the
top-level Makefile for additional configuration,
and do a ‘make dep ; make
clean‘ if you want to be sure all
the files are correctly re-made
mv .tmpconfig .config
----------------------------------------------------------------------------------------------------------------------------------------------------
第二步
[root@localhost linux]# make dep
gcc -D__KERNEL__ -E -M tty_io.c
console.c keyboard.c serial.c tty_ioctl.c pty.c vt.c mem.c defkeymap.c psaux.c
mouse.c > .depend
serial.c:538:8: 错误：宏名必须是标识符
解决办法：
cd /usr/src/linux/drivers/char
vi
serial.c
第538行,修改为这样
//#ifdef 0
#if 0
[root@localhost linux]# make dep
make[2]:
进入目录“/usr/src/linux/drivers/net”
gcc -D__KERNEL__ -E -I../../net/inet -M *.c
> .depend
/usr/include/bits/socket.h:381:24:
致命错误：asm/socket.h：没有那个文件或目录
编译中断。
解决办法:
cd /usr/src/linux/include/asm
ls
可以看到此目录下没有socket.h文件
cd /usr/include/bits
cp socket.h socket.h.bak-fedor15
vi
socket.h
第381行,注释掉
//#include <asm/socket.h>
[root@localhost linux]# make dep
make[1]: 进入目录“/usr/src/linux/fs”
gcc
-D__KERNEL__ -E -M *.c > .depend
buffer.c:108:8: 错误：宏名必须是标识符
解决办法：
cd /usr/src/linux/fs
vi buffer.c
第108行,修改
//#ifdef 0 /*
Disable bad-block debugging code */
#if 0 /* Disable bad-block debugging code
*/
[root@localhost linux]# make dep
......
gcc -D__KERNEL__ -E -M *.c >
.depend
make[1]: 离开目录“/usr/src/linux/lib”
rm -f tools/version.h
mv
.tmpdepend .depend
这步执行成功!
------------------------------------------------------------------------------------------------------------------
第三步

解决办法:

[root@localhost linux]# make zImage
gcc -D__KERNEL__ -Wall

init/main.c
cc1: 错误：unrecognized command line option ‘-m486’
make: ***
[init/main.o] 错误 1
解决办法:
cd /usr/src/linux
vi Makefile
注释掉
#ifdef
CONFIG_M486
#CFLAGS := $(CFLAGS) -m486
#else
#CFLAGS := $(CFLAGS)
-m386
#endif
或者修改为
ifdef CONFIG_M486
CFLAGS := $(CFLAGS)
-march=i486
else
CFLAGS := $(CFLAGS) -march=i386
endif
[root@localhost linux]# make zImage
gcc -D__KERNEL__ -Wall

make: ***
[init/main.o] 错误 1
解决办法:
vi /usr/include/linux/string.h
第130行的 strchr函数,修改为这样
extern
inline char * strchr(const char * s,char c)
{
register char * __res
__asm__("ax");
__asm__("cld\n\t"
"movb %%al,%%ah\n"
"1:\tlodsb\n\t"
"cmpb

"je

"testb

"movl
$1,%1\n"
"2:\tmovl
%1,%0\n\t"
"decl

:"=a" (__res):"S" (s),"0"
(c));
//:"=a" (__res):"S" (s),"0"
(c):"si");
return __res;
}
这类错误是由于gcc的进化,导致现在版本的gcc已经不需要指定如最后一个:"si" 这样的寄存器了.
