在不经意间,本人在网上看到了,一个评论,说如果没有实物开发板,可以利用一些工具模拟硬件平台,来学习Linux移植开发等。由于本人正是那种没有多少可流动现金,所以选择了Skyeye。
Skyeye本来是由清华一学生创始的,后来加入了很多同伴与其一起开发。孤身一人开发确实不容易,但很多情况下都得独自开发,像我这种普通高校学生,很难会做出一下令人有兴趣的,而且还会让人加入的事情。所以只能自己努力坚持,才能达到自己的理想目标,即使艰难也得继续,技术路确实不好走啊。这里就不再废话了。
平台描述:
Skyeye是基于Linux开发的,你可以使用Linux来安装,也可以在Windows下使用Cygwin来安装,由于个人认为,Linux是开发必需的平台,所以我将在下文认Linux安装作为实例教程。
我的电脑安装的是Fedora14(关于Linux的一些学习经常,本人的信息方向论坛有讲述一些,可以作为入门参考 http://blog.csdn.net/bakasen/category/787512.aspx) 。可能在网上很多人都听说过Red Hat、Ubuntu等 ,但是Fedora却是很少听见,其实Fedora的前身就是Red Hat,由于Red Hat 公司将Red Hat Linux的开发放到了开源社区(其自身保留Red Hat的企业版),因此改名为Fedora。由于自己没有玩过Red Hat所以也不知道Red Hat与Fedora的差别有多少。所以我只能以我自己在Fedora14上的安装经验告诉大家(不过不同的Linux上安装,差别并不是太大)。
Skyeye安装:
目前最新的Skyeye版本是1.3.2,你可以到 http://www.skyeye.org 下载最新版的Skyeye。
1、安装前准备:
以前的Skyeye是不支持LCD的,但是现在新出的版本都支持LCD,由于Skyeye的LCD是以GTK为基础的,所以安装Skyeye前一定要安装GTK,但是在不同的发行版中,一般都会自带GTK,所以GTK的安装与否就取决于Skyeye的要求了。
2、用yum命令安装一些软件包
#yum install ncurses ncurses-devel glibc glibc-devel libXpm libXpm-devel texinfo xterm xorg-x11-fonts-misc
3、上面软件包安装完成后:
#su #fc-cache -fv
4、手动创建一些文件头.用vi创建复制进去保存即可
4.1、创建/usr/include/sys/stropts.h 文件:
4.1.1、拷贝下面文件

4.1.2、输入命令行,进入后,按i进入文字编辑,粘贴上面文件后,按Ecs,再输入:wq,保存并退出vi。
#vi /usr/include/sys/stropts.h
4.2、创建/usr/include/bits/stropts.h
4.2.1、 拷贝下面文件

4.2.2、输入命令行,进入后,按i进入文字编辑,粘贴上面文件后,按Ecs,再输入:wq,保存并退出vi。
#vi /usr/include/bits/stropts.h
4.3、创建/usr/include/bits/xtitypes.h
4.3.1、 拷贝下面文件
/* bits/xtitypes.h -- Define some types used by <bits/stropts.h>. Generic. Copyright (C) 2002 Free Software Foundation, Inc. This file is part of the GNU C Library.

4.3.2、输入命令行,进入后,按i进入文字编辑,粘贴上面文件后,按Ecs,再输入:wq,保存并退出vi。
#vi /usr/include/bits/xtitypes.h
5、下载Skyeye,并解压
由于时间关系,我已经下载好skyeye-1.3.2_rc1.tar.gz了,如果还没有下载,请到 http://www.skyeye.org下载。
使用cd命令,把当前路径转到存放 skyeye-1.3.2_rc1.tar.gz的地方,输入如下命令。
#tar zxvf skyeye-1.3.2_rc1.tar.gz
6、开始安装Skyeye
先进入刚才解压的文件路径。
#./configure #make lib #make #make install_lib #make install
我安装时是按照这一流程操作的,如果上面操作步骤有问题,可以在出错信息中查找原因。
7、环境配置
由于Skyeye默认是安装在/opt/skyeye/中,如果想打开Skyeye需要输入/opt/skyeye/bin/skyeye 才能打开,所以配置一个全局变量,只要在打开终端时,就可以直接输入skyeye才运行Skyeye了。
我是对/etc/profile进入修改的,但是网上写,推荐修改/etc/bashrc。
#vi /etc/bashrc
进入后,按i,到文件末尾加上,具体如下(请完整复制下面代码,因为这种代码格式,有点不一样,少了个空格都可能会出错,加上if是为了防止skyeye被删后,还在PATH中加入其路径):
if [ -d /opt/skyeye ] then PATH=/opt/skyeye/bin/:$PATH fi
然后按Esc,输入:wq,保存并退出,再输入
#source /etc/bashrc
好了,试试直接输入skyeye,会不会有什么反应吧,如果没有,请注销或者重启一下。
8、运行测试用例
默认情况下,Skyeye是安装在/opt/skyeye中,里面有一个名为testsuite的文件夹,这个文件夹中,放的就是一个arm_hello的测试例子。
#cd /opt/skyeye/testsuite/arm_hello/ #skyeye -e arm_hello
以Skyeye打开arm_hello,进入下面画面。
输入start ,回车,进入下面画面。
输入run,回车,例子开始运行(不知道是我的问题还是什么 ,输入start是会回显出来,但是输入run时,有时没有回显出来,应该是start后,所以输入有时会没有回显),如下。
好了,这里Skyeye已经安装好了。
其实Fedora14系统本身自带了GTK,由于当初不清楚,所以自己还是安装了GTK,过程还是挺曲折的,由于篇幅问题,这里就不再讲述了。
