*编译主机CPU架构：64位 <br>
<span style="background:#CCCCCC">compife CPU architeture of host：64 bit</span><br>
*编译主机系统：Linux <br>
<span style="background:#CCCCCC">compife system of host：Linux</span><br>
*Linux发行版：Ubuntu <br>
<span style="background:#CCCCCC">Linux release version：Ubuntu</span><br>
*Ubuntu版本类型：服务器版 <br>
<span style="background:#CCCCCC">Ubuntu version type：server version</span><br>
*Ubuntu版本号：12.04.5 <br>
<span style="background:#CCCCCC">Ubuntu version no.：12.04.5</span><br>
*Ubuntu系统类型：x86-64 <br>
<span style="background:#CCCCCC">Ubuntu system type：x86-64</span><br>
　　<span style="color:red">注意：开发主机请使用ubuntu 12.04.5 x86-64（桌面版或服务器版均可），使用其他发行版的Linux或Ubuntu的其它版本可能会遇到的不必要的问题。 <br>
　　<span style="background:#CCCCCC"><span style="color:red">note：for development host please use ubuntu 12.04.5 x86-64（either desktop version or server version is ok），some unneccesory problems may arise if other release versions or other buntu versions are used.</span></span><br>


== '''操作说明(operating instruction) ''' ==
<span style="color:red">1）文档中以“$”开头的行，其后是Linux命令。 <br>
<span style="background:#CCCCCC">lines starting with “$”in document，following it will be Linux command。</span><br>
2）文档中所有的Linux命令建议手动输入到Linux主机执行（直接复制、粘贴到Linux主机上执行，可能会执行失败）。 <br>
<span style="background:#CCCCCC">lines starting with “$”in document，following it will be Linux command。</span><br>
3）文档中的Linux执行命令，如果空格后的下一个字符是“-”的（如：sudo apt-get –y install之类的），请手动输入到Linux主机执行（直接复制、粘贴到Linux主机上执行，通常会执行失败）。 <br>
<span style="background:#CCCCCC">if following a space is charater “-”in any executing command in the document（e.g：sudo apt-get –y install and the like），please enter manually to Linux host for execution（direct copy,pasting to Linux host to run,which may cause failure of execution）。</span><br>
4）文档中所有一行没写完的Linux命令请手动输入到Linux主机执行，（因为复制、粘贴命令不能包含类似“换行符”之类的特殊字符）。 <br>
<span style="background:#CCCCCC">any line with unfinished Linux command in the document,please enter manually to Linux host for execution（since copy,pasting can't contain special charater such as “line break”）。 </span><br>
5）按文档输入并执行Linux命令时注意观察命令的执行结果与文档图片中的是否一致，以确认命令是否输入有误及是否执行失败。 <br>
<span style="background:#CCCCCC">pay attention to whether the executing result is consistent with image in the document or not when enter and execut Linux command,to ensure whether there is an incorrect entry of command or failure of exectuion. </span><br>
6）第一遍编译请严格按照文档进行，否则可能出现莫名其妙的错误。<br>
<span style="background:#CCCCCC">please follow strictly the documents to compife for the first time,otherwise there may arise some unexpected mistakes。</span></span><br>


== '''截图说明(screenshots instruction)''' ==
为使视图看起来简洁整齐，截图中的命令提示符统一使用<span style="color:green">myzr</span>$。<br>
<span style="background:#CCCCCC">To make the view look neat and tidy ,<span style="color:green">myzr</span>$ should be used uniformly as command prompt in the screenshots。</span><br>

== '''图片中的Linux命令(Linux command in image)''' ==
在文档的图片中观察“linyn@u12045-serv:~$”开头的行可以直观的看到输入的<br>
<span style="background:#CCCCCC">In the image of the document, you can see the input Linux command visually from the lines that start with “linyn@u12045-serv:~$”</span><br>
