编译mysql连接器用mingw编译C++，编译错误

Question

我在编译mysql连接器时遇到了一个问题，用官方网站发布的mingw，你应该运行cmake来配置源码，然后运行一个mingw32-make ...该cmake需要安装boost库，所以我得到它并编译它（它说很多更新，40个目标跳过，无法更新24）。

之后，试图在MySQL连接器源码上运行cmake，它输出没有错误，工作得很好，当试图做最后一步mingw32-make时，它提供了很多错误，然后很多重定义...日志在下面。请帮助我，我真的需要它。

Answer 1

MySQL的连接器C++源代码是垃圾，可惜。

它重新定义在标准库中定义的函数，然后包括标准库，或依赖于不包括在每一个实现非标准功能。

由于标准库不检查，看看它的功能和结构已经确定，你结束了多个定义错误所有的地方。

另外，由于mysql连接器尚未被移植到mingw，所以问题会变得更糟。要在Windows上编译，您需要使用Visual Studio。

它变得更好。他们只支持Visual Studio的8和9

如果您按照这些说明准确， http://dev.mysql.com/doc/connector-cpp/en/connector-cpp-installation-source-windows.html ，那么你也许可以得到它的工作，但你不能从任何版本号偏离。使用旧版本的cmake，旧版本的visual studio。他们没有测试过，也不关心与任何现代版本的构建工具的兼容性。
