3 下载文件
1> skyeye 最新版
wget ... ye-1.2.4_Rel.tar.gz
2> arm开发环境
有了这个就可以在ubuntu下编译arm上可以用的软件了，就一个包安装了就ok了，当然如果你不怕麻烦或者想自己做一个环境出来也是可以的，那就自己学一下怎么搭建交叉编译环境吧
wget ... s-20040427.sh%C2%A0
3> 如果要测试你的环境是不是ok了，是不是可以正常的使用skyeye来模拟arm开发板，那么下面的软件是必须的
... stsuite-2.3.tar.bz2
4> 我们要安装uClinux 那么这个包就必须下下来
... est-20070823.tar.gz
二//--------------------------------------------------------------------------
安装arm tool
# mv arm-elf-tools-20040427.sh_ arm-elf-tools-20040427.sh

查看了以后，安装一ok了，我们现在测试一下是不是真的ok了，nano建立一个文件
# nano test.c
然后输入
#include
int main()
{
printf("ARM tools is OK\n");
return 0;
}
然后ctrl+o保存退出
我们编译出来这个测试文件
# arm-elf-gcc -Wl,-elf2flt -o test test.c
看清楚了，W后面的是个小写的L，不是数字1哦
然后我们查看一下是不是编译ok了
# ls -lh test*
-rwxr--r-- 1 root root 29K Dec 14 12:45 test
-rw-r--r-- 1 root root 136 Dec 14 10:38 test.c
-rwxr-xr-x 1 root root 76K Dec 14 12:45 test.gdb
# file test
test: BFLT executable - version 4 ram
# file test.gdb
test.gdb: ELF 32-bit LSB executable, ARM, version 1, statically linked, not stripped
我们运行一test看看，呵呵，肯定出错，出错也看看
# ./test
bash: ./test: cannot execute binary file
在arm下跑的肯定不能x86下跑了
我们继续
安装skyeye

2> make一下看
# make
--------------------------- NOTICE ------------------------------
If you always get error, please run "make NO_CHECK=1" instead.
-----------------------------------------------------------------
Checking whether host is big endian ... no
Checking gcc ... OK ( gcc version: 4.1.3 )
Checking whether the compiler supports x86 asm ... FAILED
*** It seems that the compiler don't support inline x86 AT&T ASM codes.
*** Run "make NO_DBCT=1" instead to ignore it.
make: *** [check] Error 1
重新按照下面的输入重新make
# make clean
# make NO_DBCT=1
耐心等待一下，我的计算机大概两分钟就ok了，直到下面的出现就表示ok了
****
**** The binary file located at 'binary/skyeye', enjoy it.
****
然后我们编辑一下环境变量，把path修改一下，让系统能直接找到skyeye
# nano /etc/environment
看第一行
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/skyeye/binary"
修改如上面的这样，然后保存--按快捷键 Ctrl+o，然后打回车
然后exit退出到登陆界面重新登陆一下，让刚才修改的生效
我们测试一下看ok了没
# skyeye -h
------------------------- SkyEye -V1.2 ---------------------------
Usage: SkyEye [options] -e program [program args]
Default mode is STANDALONE mode
------------------------------------------------------------------
Options:
-e exec-file the (ELF executable format)kernel file name.
-l load_address,load_address_mask
Load ELF file to another address, not its entry.
-b specify the data type is big endian when non "-e" option.
-d in GDB Server mode (can be connected by GDB).
-c config-file the skyeye configure file name.
-h The SkyEye command options, and ARCHs and CPUs simulated.
------------------------------------------------------------------
----------- Architectures and CPUs simulated by SkyEye-------------

出现了这个界面说明skyeye已经ok了
我们测试一下看看

OK我们进到具体的目录了，我们现在测试一下看能不能把基本的测试跑起来
运行下面的命令
# skyeye -e vmlinux -c skyeye.conf
简单的说一下，-e表示指定加载什么文件为内核，-c表示什么文件是配置文件
好，我们看一下
# skyeye -e vmlinux -c skyeye.conf
big_endian is false.

ok，我们查看过cpuinfo文件了，确定可以模拟了，呵呵，skyeye安装ok了
