各位好!小妹在使用skyeye仿真内核及文件系统配置时出现错误,请各位大侠指点!
源码采用linux-2.4.18-rmk7.tar.bz2,交叉编译工具使用cross-2.95.3.tar.bz2,仿真平台skyeye,均是从www.akaembed.org上下载
busybox-1.00-pre10.tar.gz从www.busybox.net上下载
使用skyeye仿真使出现下面错误

我在使用busybox-1.00-pre10.tar.gz时出现了一些问题:
1.busybox-1.00-pre10下的Makefile中,并没有DOSTATIC项,于是我在make menuconfig中将busybox选为静态编译
2.make时出现错误,显示 lbbb/loop.c 因找不到引用的<linux/version.h>出错,我将此句注释后,make成功
另附
1.根据说明,将busybox-1.00-pre10/init/init.c中的
#define INIT_SCRIPT "/etc/rc.d/rc.sysinit"
改为
#define INIT_SCRIPT "/etc/inittab"
2.编辑/mnt/img/etc/inittab为
::sysinit:/etc/rc
3.编辑/mnt/img/etc/rc为
#!/bin/sh
hostname armlinux
mount -t proc proc /proc
mkdir /var/tmp
mkdir /var/log
mkdir /var/run
mkdir /var/lock
cat /etc/motd
4.编辑/mnt/img/etc/fstab为
none /proc proc defaults
5.主机系统安装的时redhat9.0,采用的linux-2.4.20的内核
迫切请大侠指点! |
