解决方案：我已决定为有相同问题的人提供分步指南。我不知道这是否完全解决了所有问题，但它确实让你编译了我将提供的代码片段。如果有任何错误请评论，以便我可以解决它们。这是为了帮助那些大多放弃失败尝试的人，坦率地说，整个过程应该记录在案。对不起，很长的帖子：P
STEP BY STEP FOR SETTING UP MYSQL CONNECTOR/C++ FOR 2010 MICROSOFT VISUAL C++ EXPRESS:
FILES NEEDED:
Windows x86 32 Bit ZIP: Connector/C++ -> http://dev.mysql.com/downloads/connector/cpp/
Windows X86 32 Bit ZIP: Connector/C -> http://dev.mysql.com/downloads/connector/c/
BOOST -> http://www.boost.org/users/download/
The reason why 62bit doesn't work is because you are using the express edition. After you have downloaded all those files, extract them. I keep mine in C (for ease of access). Now open up MVC++ 2010 EXPRESS.
File -> New -> Project
Win32 Console Application
Next
Check Empty project
Finish
Create your first .cpp. I call mine main.cpp
Project -> Properties
C/C++ -> General -> Additional Include Directories -> C:\mysql-connector-c++-noinstall-1.1.0-win32\mysql-connector-c++-noinstall-1.1.0-win32\include
C/C++ -> General -> Additional Include Directories -> C:\mysql-connector-c++-noinstall-1.1.0-win32\mysql-connector-c++-noinstall-1.1.0-win32\include\cppconn
C/C++ -> General -> Additional Include Directories -> C:\boost_1_49_0
Linker -> General -> Additional Library Directories -> C:\mysql-connector-c++-noinstall-1.1.0-win32\mysql-connector-c++-noinstall-1.1.0-win32\lib
Linker -> General -> Additional Library Directories -> C:\mysql-connector-c-noinstall-6.0.2-win32\mysql-connector-c-noinstall-6.0.2-win32\lib
The reason why we downloaded the Connector/C is because it has two files we need: libmysql.lib and libmysql.dll
Linker -> Input -> Additional Dependencies -> mysqlcppconn.lib
Linker -> Input -> Additional Dependencies -> libmysql.lib
If you change to Release, youll have to enter in the information again.
In your main.cpp place the following code and build it:

你应该得到int8_t的错误。双击位于以下位置的config.h：c：\ mysql-connector-c ++ - noinstall-1.1.0-win32 \ mysql-connector-c ++ - noinstall-1.1.0-win32 \ include \ cppconn \ config.h。双击它以显示它。现在只注释掉所有typedef应该只有8.将libmysql.dll（在Connector / C中）和mysqlcppconn.dll（在Connector / C ++中）放在编译器输出构建的文件夹中。完成后保存并运行。
旧帖没有看
我已逐字地按照本网站上的步骤进行操作：http://blog.ulf-wendel.de/?p=215 但我仍然遇到编译错误。我不是新的链接库，或包括目录，但我可以使用一个新的超级英雄谁用mysql连接器/ c ++和2010快递制作应用程序...来制作一个简单的KISS示例。我整天都在磨牙。 示例来源：http://www.tidytutorials.com/2009/07/mysql-connector-c-example-windows-clexe.html（已更改数据库）

更新：我也遵循了这一点：http://forums.mysql.com/read.php?167,492097,492097#msg-492097我甚至使用了C ++和C连接器（单独的构建版本）以及每个64位和32位版本的BOTH测试（总共4次测试）。我已经下载了boost并将其链接起来。我正在使用的新代码我将在下面发布来自官方mysql网站。两个版本都会产生相同的错误。

帮助将不胜感激！
更新2：view_findpost_ p _1474626“＆gt; http：//www.dreamincode.net/forums/topic/253647-question-regarding-connecting-to-mysql-50-using-visual -studio-2010 / page_ view _findpost_ p _1474626这家伙似乎认为这是因为config.h在编译时与stdint.h冲突，因为在config.h中有一个#typedef for int8_t。必须有一个解决方案。我甚至可以使用任何其他可以连接到本地MySQL数据库的库（免费），但我真的很想把它想出来帮助所有人。
答案 0 :(得分：0)
由于有很多关于C ++和MySQL连接器的问题，并且很难让它工作，我会回答这个问题，即使这个问题就像1年前一样。
解决方案非常简单，只需要在cppcon / config.h文件中注释所有typedef
