在最新的版本中,windows环境与linux环境下使用一套代码。比如mysql-6.0.4-alpha版本中的INSTALL-WIN-SOURCE文件的描述:

  TobuildMySQLonWindowsfromsource,youmustsatisfythe
  followingsystem,compiler,andresourcerequirements:
  *Windows2000,WindowsXP,ornewerversion.WindowsVistais
  notsupporteduntilMicrosoftcertifiesVisualStudio2005on

  *3GBto5GBofdiskspace.

  通过这样的方法,生成项目文件,从而可以通过vs工具进行编译。在先前的版本中,windows下的代码和linux下的代码是两个压缩包,比如windows下的一个软件包名为,mysql-5.1.7-beta-win-src.zip。

  这里我选择5.1.7作为分析的对象。

  安装代码的步骤:

  1.解压缩文件包mysql-5.1.7-beta-win-src.zip。

  2.使用vs2003打开项目文件mysql.sln。

  3.设置mysqld项目为启动项目
4.在mysqld的属性页设置命令参数为:--console。这样就可以用debug方式调试代码了。

  5.设置断点,比如查询的总入口是handle_select函数。

  6.编译mysql项目,将会在mysql-5.1.7-betaclient_debug目录下生成mysql.exe
7.使用“启动新实例”或者“进入单步执行新实例”进行调试。

  8. mysql-5.1.7-betaclient_debug目录下生成mysql.exe,执行语句,将会执行到断点进行调试。
