ubuntu server 12.04上的skyeye1.3.5安装和使用(打造最精确的安装步骤和注意事项)
http://www.ithao123.cn/content-686371.html
1、环境介绍
ubuntu版本:12.04 (cat /etc/issue 或lsb_release -a查看）
root@xumin:~# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 12.04.4 LTS
Release: 12.04
Codename: precise
skyeye版本：1.3.5
下载地址:
http://sourceforge.net/projects/skyeye/files/skyey e/skyeye-1.3.5/
安装前准备工作
1、apt-get install apt-get install libgtk2.0-dev pkg-config libatk1.0-dev libpango1.0-dev libfreetype6-dev libglib2.0-dev libx11-dev binutils-dev libncurses5-dev libxpm-dev autoconf automake libtool python-dev
2、python下载源码python2.7.6安装(记得要下载python 2.7版本的)，下载地址:
http://www.python.org/download/
安装步骤为（python 2.7的安装对是否能成功安装skyeye有决定性作用）：
1、解压python，并进入解压后的目录
2、./configure --prefix=/usr/local/python2.7 --enable-shared --enable-unicode=ucs4
注意：没有这个两个编译选项，你会发现有无穷无尽的错误在等着你解决，不过我仍然相信你乐于去解决。
3、make && make install
然后你需要将python的lib库导出，下面是方法:
vim /etc/ld.so.conf 加上include /usr/local/python2.7/lib 保存退出
然后/sbin/ldconfig
说明：python的内部是使用unicode来处理的，但是unicode的使用需要考虑的是它的编码格式有两种，一是UCS-2，它一共有65536个码位，另一种是UCS-4，它有2147483648g个码位。在编译时通过--enable-unicode=ucs2或--enable-unicode=ucs4来指定的。那么我们自己默认安装的python用的什么编码怎么来确定呢？进入python安装后的目录，找到执行python，然后./python
\import math,sys
\print("math.pi=={0.pi} sys.maxunicode=={1.maxunicode}".format(math, sys))
quit()
如果sys.maxunicode==65535,那么就是UCS-2,如果输出是sys.maxunicode==1114111，就是UCS-4编码。
3、skyeye的安装
1、读安装步骤的INSTALL，不要擅作主张自己./configure && make && make install，而应该是
./configure --prefix=/opt/skyeye && make lib && make && make install_lib && make install
中间出现任何编译报错有三个原因，一个是前面要装的依赖包没有安装，一个是python2.7没有安装ok ，还一个可能是系统缺少某些库，或者本身不缺，但库路径没有导出。
2、skyeye的使用
安装成功后，进入/opt/skyeye/testsuite/arm_hello，输入
skyeye -e 可执行文件名 -c skeeye.conf
会出现：
root@xumin:/opt/skyeye/testsuite/arm_hello# skyeye -e arm_hello -c skyeye.conf SkyEye 1.3.5

Get more information about it, please visit the homepage http://www.skyeye.org.
Type "help" to get command list.
(skyeye) start
In create_uart_console
mmap DRAM, size=0x400000, return 0x1000000
1 core is initialized.
(skyeye) run
(running)stop
不要按照网上的某些人不合理的步骤如：
skyeye
start
run
如果你这样输入，会出现下面的错误。
[SkyEye Crashed]. Please report the following output to [email protected].
In bus_read, Bus read error, can not find corresponding bank for addr 0x908,pc=0x910
如果你比较认真，你可能会进入/opt/skyeye/testsuite/sparc_hello 目录测试sparc_hello
你会出现：
(skyeye) *** Unknown command: EOF
*** Get commands with 'help' cmd
那是因为代码的测试程序的skyeye.conf中uart:mod=stdio导致的，改成uart:mod=term后再看看吧，你肯定会心情愉悦的。
网上有一段很详细的使用方法（http://www.iteedu.com/embed/embedarticles/skyeyeLinx.php）：
在/opt/skyeye/testsuite/目录下有一个测试程序”arm_hello“。
1).进入/opt/skyeye/testsuite/;
2).输入sudo skyeye -e arm_hello命令，进入skyeye命令行界面;
3).然后运行"start"命令加载配置和初始化目标机，同时在主机上会显示一个xterm的窗口，窗口标题 为"uart_instance";
4).然后我们可以输入"run” 命令来启动helloworld的测试用例;
5).我们输入"stop" 命令来停止目标板;
6).输入 "info regitsters" 查看当前的寄存器的数值;
7).输入 "disassemble" 命令进行反汇编0x100004c，例如："disassemble 0x100004c";
7.skyeye的终端是用term(Ubuntu是xterm)，显示特别难看，我们修改一下xterm的显示特性就可以了。
修改~/.Xresources就可以了(没有就自己创建一个)
范例代码:
xterm*locale: true
xterm.utf8: true
xterm*utf8Title: true
xterm*faceName: Monaco:pixelsize=14
xterm*faceNameDoublesize: WenQuanYi Zen Hei:pixelsize=15
然后用命令
xrdb -load ~/.Xresources
重启或导入设置就可以了
3、如果你觉得在嵌入式虚拟机skyeye上玩得很过瘾，但无人指路，你首先肯定会想到书了，是的。有这样一本书：
一步一步写嵌入式操作系统--ARM编程的方法与实践.pdf
下载地址：http://ishare.iask.sina.com.cn/f/20935970.html?from=like
它肯定是为你量身订做的，开始你的神奇之旅吧。

5、因为ubuntu所装系统的包或库因人而已，所以不可能将所有安装中错误都一一列出，同学们可以在度娘/Google上搜索关键语句，查找解决方法(当然我主要先分析出错原因）。一般出现问题要么是缺少了某些库（静态或动态的），要么是存在这个库，系统库路径没有包含存有该库的路径。另外解决问题时，一定要做好备份和记录，这是一个好的前提。
下面是本人定位记录，相信能帮助到大家：
说明：本人系统有ubuntu默认安装的python2.7.3，然后有本人前面提到的python2.7.6，这是本人编译安装的。第1个问题和第2个问题类似，所以只解释第1个问题。 根据错误提示 ImportError: /usr/local/lib/python2.7/lib-dynload/_ctypes.so: undefined symbol: _PyInt_AsInt。说明_ctypes.so引用的_PyInt_AsInt符号，在依赖的库中没有定义，前面提到skyeye的问题，以我的经验，一般是由python引起的，所以我们首先ldd看一下/usr/local/lib/python2.7/lib-dynload/_ctypes.so对python的依赖库，发现libpython2.7.so.1.0 => /usr/lib/libpython2.7.so.1.0 (0xb75a6000)，然后通过readelf查看/usr/lib/libpython2.7.so.1.0是否存在符号_PyInt_AsInt的定义，readelf -a /usr/lib/libpython2.7.so.1.0 |grep _PyInt_AsInt ，很显然没有（有的话我们不必讨论该问题，不是么？），就表示/usr/lib/ 下的这个libpython2.7.so.1.0 库，没有定义该符号，我们可以在/usr 目录下全局搜索，看libpython2.7.so.1.0 是否在其他目录存在，特别是我们自定义安装python2.7.6的相关lib路径下，显然我们在/usr/local/python2.7/lib/ 目录下找到了定义_PyInt_AsInt符号的libpython2.7.so.1.0 库。具体细节见下面的定位记录。这样我们只需把我们自定义安装python2.7.6的相应动态库拷贝过来即可，当然拷贝覆盖之前要做好备份！ 第3个问题是运行skyeye OK后，在通过gdb调试程序时出现了错误AttributeError: 'module' object has no attribute 'pydebug，/usr/lib/python2.7/下是系统安装python2.7.3生成的（通过dpkg -L python或者whereis python 可以知道系统默认的python2.7.3安装路径），所以我打算先将/usr/lib/python2.7/备份，没想到我输入gdb后竟然成功，通过strace分析发现gdb运行的是/usr/local/python2.7/lib/python2.7/ 目录下的sysconfig.py，当然也可以将/usr/local/python2.7/lib/python2.7/ 拷贝到/usr/lib/。
