内核编译求教

whlflang

问题1:内核编译是驱动开发的先决条件么?





问题2我的内核编译,使用VMware6 redhat9的linux 本身带2.4.20.8的内核进行 linux-2.6.20.4.tar.gz 编译  在make bzImage是出现问题 困扰比较久了请指点

[root@localhost root]# cd /usr/src/redhat                        进入规范文件目录下
[root@localhost redhat]# ls
BUILD  modutils-2.4.5-1.src.rpm  RPMS  SOURCES  SPECS  SRPMS
[root@localhost redhat]# rpm -e --nodeps modutils                 强行卸载原有的modutilsRPM包

[root@localhost redhat]# rpm -ivh modutils-2.4.5-1.src.rpm        （把源代码包安装到了/usr/src/redhat目录下）

[root@localhost SPECS]# cd ../RPMS/i386                                        转入刚生成的二进制的RPM包所在位置

[root@localhost i386]# rpm -ivh modutils*.rpm                                刚生成两个[modutils-2.4.5.1-1.i386.rpm与modutils-debuginfo-2.4.5.1-1.i386.rpm]二进制的RPM包，一起安装

[root@localhost i386]# cd /usr/src
[root@localhost src]# ls
debug  linux-2.4  linux-2.4.20-8  module-init-tools-3.2.2.tar.bz2  redhat         (  module-init-tools安放目录)


安装module-init-tools. 它会替代depmod [/sbin/depmod]和其他工具.

[root@localhost src]# tar -jxvf module-init-tools-3.2.2.tar.bz2
[root@localhost src]# cd module-init-tools-3.2.2

[root@localhost module-init-tools-3.2.2]# ./configure --prefix=/sbin

[root@localhost module-init-tools-3.2.2]# make
[root@localhost module-init-tools-3.2.2]# make install

[root@localhost module-init-tools-3.2.2]# ./generate-modprobe.conf /etc/modprobe.conf


[root@localhost module-init-tools-3.2.2]# cd /usr/src
[root@localhost src]# ls
debug      linux-2.4.20-8       module-init-tools-3.2.2          redhat
linux-2.4  linux-2.6.20.4.tar.gz   module-init-tools-3.2.2.tar.bz2


tar –zvxf linux-2.6.20.4.tar.gz
ln –s linux-2.6.20.4 linux
cd linux
make mrproper


方法1:
make menuconfig (我没有修改采用默认的设置)
make  bzImage >/dev/null

方法2 make menuconfig 进行了一部分配置
make  bzImage >/dev/null

你在rh9上编译2.6的内核啊。建议在2.6的发行版上编译2.6的内核。

whlflang

求教方法或者提示,软件之类的

Godbach

建议LZ直接使用2.6内核的发行版，然后在此基础上重新编译内核

LZ要升级gcc的
