Linux内核编译

[xiahou0791]

各位大侠，小弟在编译Linux内核的时候总是出现这个问题：
drivers/block/block.o: In function `ramdisk_updatepage':
drivers/block/block.o(.text+0x2840): undefined reference to `cpu_CPU_NAME_cache_
clean_invalidate_range'
drivers/block/block.o: In function `rd_blkdev_pagecache_IO':
drivers/block/block.o(.text+0x29f8): undefined reference to `cpu_CPU_NAME_cache_
clean_invalidate_range'
make: *** [vmlinux] Error 1
这是怎么回事啊？研究了半天没弄清楚，麻烦大伙儿支个招啊！谢啦！

配置不对?或者重新配置后没make clean?

尝试以下几种方法：
1. #make clean; make all
2. #make menuconifg 配置好内核选项，或者使用正确的.config文件。
3. 从www.kernel.org下载你想要的版本的kernel源码。

唉，以上这些方法我都试了。有哪位能给出完整的内核编译过程吗？包括所要编译内核的版本和所用编译器的版本号。

或直接make mrproper,然后再从新配，现在pc的的都不用make dep吧……

做个记号！
明天补上在Ubuntu10.4下编译2.6.32的过程！

既然这样，你下一个和你用的发行版内核版本一样的内核下来，然后
解压
cp /boot/config-`uname -r` ./.config
make menuconfig
在下面找load config file 点ok
make
make modules
make modules_install
make install
重启

Linux-2.6.28移植
移植Linux2.6.28到 亿道公司的EELIOD xsbase270开发板的资料,搂主看下有帮助不?

1、修改linux-2.6.28目录下的Makefile

将

ARCH ?= $(SUBARCH)
CROSS_COMPILE ?=

改为

ARCH ?= arm
CROSS_COMPILE ?=/opt/arm-linux-4.2.1/bin/arm-linux-

//这里的/opt/arm-linux-4.2.1/bin/arm-linux-为编译器的绝对地址

2、在linux-2.6.28/arch/arm/mach-pxa目录下增加一个xsbase270.c文件（实际上从该目录下的mainstone.c复制而来），然后根据实际平台进行修改。
