在Ubuntu在安装SkyEye及测试

有一堆依赖的关键包，比如gtk的依赖，一般Ubuntu 都默认安装了，稳妥起见，运行下面的代码：
sudo apt-get install libgtk2.0-dev pkg-config libatk1.0-dev libpango1.0-dev libfreetype6-dev libglib2.0-dev libx11-dev binutils-dev

我的系统是ubuntu 9.10 用apt装了skyeye 但是运行出出错
root@hanls-desktop:~# skyeye
skyeye: error while loading shared libraries: libbfd-2.19.90.20090909.so: cannot open shared object file: No such file or directory
root@hanls-desktop:~#

解决方法：
在ubuntu 9.10中，libbfd的版本是libbfd-2.20.so，我想libbfd-2.19.90.20090909.so到libbfd- 2.20.so的改动应该不是很大吧，所以我把libbfd-2.20.so拷贝一份，然后将文件名改成libbfd- 2.19.90.20090909.so就可以了。libbfd-2.20.so在/usr/lib目录下。

sudo cp /usr/lib/libbfd-2.20.so /usr/lib/libbfd-2.19.90.20090909.so

sudo mv /usr/lib/libbfd-2.20.so /usr/lib/libbfd-2.20.so.bak

然后输入skyeye

成功输出以下。

**************************** WARNING **********************************

your elf-format image filename. Or you only want to run binary image,
you need to set the filename of the image and its entry in skyeye.conf.

    看到如上情形，运行成功
    ctrl+c退出到#
    (6)编译uClinux内核
    #tar vxzf uClinux-dist-20040408.tar.gz
    生成文件夹uClinux-dist,将其移动到/usr/src/
    #mv uClinux-dist /usr/src/
    然后进入uClinux-dist下
    #cd /usr/src/uClinux-dist/
    <1>菜单界面配置
    #make menuconfig
    选择如下:   
    --- Select the Vendor you wish to target
             (GDB) Vendor
     --- Select the Product you wish to target
              (ARMulator) GDB Products  
    (linux-2.4.x) Kernel Version
    (uClibc) Libc Version        
    [ ] Default all settings (lose changes)
    [ ] Customize Kernel Settings        
    [ ] Customize Vendor/User Settings
    [ ] Update Default Vendor Settings
    然后Esc退出
    Do you wish to save your new kernel configuration?
                   < Yes >      < No >  
    选择yes
    如果在make menuconfig后出现错误提示，则需安装libncurses5，在新立得里安装或者
    #sudo apt-get install libncurses5-dev
    安装完后再make menuconfig
    <2>图形界面配置
    #make xconfig
    选择同上
    如果出现错误提示，则需安装tck，tk两个包，在新立得中安装，也可自己下载后安装，下载地址:

    http://www.tcl.tk/software/tcltk/downloadnow85.html
    将两个包解压后得到tcl8.5.2,tk8.5.2
    #cd tcl8.5.2
    #cd unix
    #./configure --prefix=/usr/
    #make install
    同样的方法将tk装上,在/usr/bin下会看到wish8.5,因为make xconfig调用的是wish，所以我们做一个链接
    # ln /usr/bin/wish8.5 /usr/bin/wish
    然后可以make xconfig
    无论你用菜单界面还是图形界面配置成功了，我们就可以编译uClinux的内核了
    命令进入uClinux-dist
    建立内核依赖关系，只在第一次编译内核时使用
    #make dep
    ~
    ~
    ~
    经过一段时间，如果没有错，可以进行下一步了,编译内核
    #make
    完成后可以在/images中看到这么几个文件
    image.bin linux.data linux.text romfs.img
    用romfs.img生成boot.rom文件系统
    #ln -s images/romfs.img boot.rom
    在/uClinux-dist就可以得到一个boot.rom
    编写skyeye的配置文件，新建文件skyeye.conf，在其加入以下信息:
   
    cpu: arm7tdmi
    mach: at91
    mem_bank: map=M, type=RW, addr=0x00000000, size=0x00004000
    mem_bank: map=M, type=RW, addr=0x01000000, size=0x00400000
    mem_bank: map=M, type=R, addr=0x01400000, size=0x00400000, file=./boot.rom
    mem_bank: map=M, type=RW, addr=0x02000000, size=0x00400000
    mem_bank: map=M, type=RW, addr=0x02400000, size=0x00008000
    mem_bank: map=M, type=RW, addr=0x04000000, size=0x00400000
    mem_bank: map=I, type=RW, addr=0xf0000000, size=0x10000000

    完成这一步就可以在skyeye中运行我们编译的内核了
    #skyeye -e linux-2.4.x/linux
