让人又爱又恨的matlab2008a之mex

    在matlab2008a下对c 进行编译，出现一系列的变量不能识别问题，然后百度，把头文件提前，编译仍然通不过，此刻才发现microsoft visio2008 已经不能使用（无法读C代码），到控制面板下更改却不能升级，气急败坏下直接卸载以及一系列的SDK2005和2010。百度安装文件，下载，再安装（3个小时过去了）。

又一轮

安装的visual studio  2008 不能编译，给定的例子都通不过，还是怀疑compiler。太不给力了，你说急人不急人! 卸载之前的2010的SDK还可以进行调试，卸载之后直接罢工。想以前装的时候也是费了很大的力才得以正常工作........

新的一天又开始，还得在这里下功夫，装个可以用的编译器还真不简单，怪不得我那么讨厌重装系统！

继续搞visual studio 2008，光装了不行，还必须得升级。于是乎重新搜索studio的升级方案，发现要一个crackvs2008forwindows7软件。

在优快云里下载的crackvs2008forwindows7软件，点击“Bug 微软”，即在“VS2008的安装卸载程序”维护界面下方出现序列号填写框，填入序列号“PYHYP-WXB3B-B2CCM-V9DX9-VDY8T”，升级成功。

一上午过去，果断卸载VS2008。重新自定义安装，默认路径，VC++选项下有X64编译，勾选，重装......

果断搞定！

总结：最最难搞的就是没有编译器，主要是因为默认安装的时候vc++下没有打钩C copliler这个选项，所以一大圈又一大圈的绕回来.......

附：如果编译的时候遇到问题，比如error C2065: “n”: 未声明的标识符 等问题，这类问题主要还是在C程序中，变量的声明要放在执行程序的最前面，所以应该自己主动去看

代码，然后把相应的变量声明放在最前面。对于是不是头文件遗失，还是要先把变量放对位置之后运行一下，执行过程会有提醒。自己学会分析，抓重点再百度。

不管如何，自己今天终于达到预期目标：））
