如何编译mysql内核(摘自老杨)
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：
To build MySQL on Windows from source, you must satisfy the
following system, compiler, and resource requirements:
* Windows 2000, Windows XP, or newer version. Windows Vista is
not supported until Microsoft certifies Visual Studio 2005 on
Vista.
* CMake, which can be downloaded from http://www.cmake.org.
After installing, modify your path to include the cmake
binary.
* Microsoft Visual C++ 2005 Express Edition, Visual Studio .Net
2003 (7.1), or Visual Studio 2005 (8.0) compiler system.
* If you are using Visual C++ 2005 Express Edition, you must
also install an appropriate Platform SDK. More information and
links to downloads for various Windows platforms is available
from http://msdn.microsoft.com/platformsdk/.
* If you are compiling from a BitKeeper tree or making changes
to the parser, you need bison for Windows, which can be
downloaded from
http://gnuwin32.sourceforge.net/packages/bison.htm.Download
the package labeled "Complete package, excluding sources".
After installing the package, modify your path to include the
bison binary and ensure that this binary is accessible from
Visual Studio.
* Cygwin might be necessary if you want to run the test script
or package the compiled binaries and support files into a Zip
archive. (Cygwin is needed only to test or package the
distribution, not to build it.) Cygwin is available from
http://cygwin.com.
* 3GB to 5GB of disk space.
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-beta\client_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-beta\client_debug目录下生成mysql.exe，执行语句，将会执行到断点进行调试。

9.相应的数据文件，见mysql-5.1.7-beta\data目录。
