今天装skyeye遇到了问题，装完以后和视频上给的不一样，但看了一位网友的博客后才确认自己装的是对的，下面是我加了一点注解，修改了些链接，大部分还是借鉴了网友的，感谢～～～

<1>arm-elf-tools-20040427无法完成对uClinx-dist-20070130的编译,推荐用arm- uclinux-tools尝试，或者用arm-elf-tools-20040427对uClinux-dist-20040408进行编译。（我选择的是编译uclinux－disk－20040408）<2>另外arm-linux-gcc与arm-elf-gcc的区别:arm-linux-gcc是针对arm+linux的开发环境 的，kernel使用的是linux，不是uclinux，arm是有硬件MMU的，而arm-elf-gcc是针对没有MMU的arm+uclinux 的开发环境，kernel使用的是uclinux，硬件是廉价的无MMU的arm芯片1.系统环境:    ubuntu8.042.准备工作:    <1>arm-linux-gcc（我是从另一本书里的光盘安装的，很长时间了，没有的朋友从下面下，链接未验证现在是否有效）

  下载地址:ARM Linux

                arm-linux-gcc版本2.95.3, 3.0和3.2        Handhelds.org                arm-linux-gcc 版本3.3.2和3.4.1        ELDK 4.1                arm-linux-gcc版本4.0.0    <2>arm-elf-tools(arm-elf-tools-20030314.sh/arm-elf-tools-20040427.sh)    下载地址:   http://opensrc.sec.samsung.com/download.html（在页面的最下方）

    下载地址:  http://opensrc.sec.samsung.com/download.html  (也在下方，但我做得时候貌似没用着阿，晕)

    <4>uClinux-dist(20040408.tar.gz)

    下载地址:  http://www.uclinux.org/pub/uClinux/dist/ （我是从这下的）

    <5>skyeye,skyeye-testsuits,skyeye-with-gdb

    下载地址:    http://sourceforge.net/project/showfiles.php?group_id=85554 （我从这下的）

3.搭建过程:

    以下操作均在root用户下进行（在每个命令前加sudo）    (1)首先安装交叉编译工具链arm-elf-tools-20040427.sh    #./arm-elf-tools-20040427.sh    即可安装成功    如出现错误提示如下：    tail: 无法打开 “+43” 读取数据: 没有那个文件或目录 （我的就出现了这个问题，别急，往下看）    gunzip: stdin: not in gzip format    按如下步骤操作：    #tail -n+43 arm-elf-tools-20040427.sh >> arm-elf-tools.tar.gz    #tar vxzf arm-elf-tools.tar.gz    即可得到文件夹usr，然后复制或移动它到/目录下    #cp -r usr /    如出现提示无法覆盖/local/man，如下操作：    #cp -r usr/local/man /usr/share/    (2)测试交叉编译是否安装成功    创建Hello.c内容如下:    #include<stdio.h>    int main()    {     printf("Hello!This is Embedded Linux!");    return 0;    }    编译如下:    #arm-elf-gcc -Wl,-elf2flt -o Hello Hello.c    #ls    Hello Hello.c Hello.gdb    可以看到编译生成BFLT格式的Hello（可用file Hello命令查看）和Hello.gdb表示编译成功    (3)安装skyeye （原帖有三种，我都试了，这里只推荐比较舒服的安装方法）    <1>一个简单的方法是在ubuntu8.04的新立得软件包管理器中搜索skyeye,可以看到有skyeye-1.2.3，安装即可    <2>或者用命令#sudo apt-get install skyeye    (3)测试skyeye是否安装成功    #skyeye       **************************** WARNING **********************************    If you want to run ELF image, you should use -e option to indicate    your elf-format image filename.
