解决方案：我决定为遇到相同问题的人制作一个分步指南。我不知道这是否完全解决了所有问题，但它确实可以让您编译我将提供的代码片段。如果有任何错误，请发表评论，以便我可以修复它们。这是为了帮助那些大部分因失败尝试而放弃的人，坦率地说，整个过程应该被记录下来。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:

您应该得到 int8_t 的错误。双击 config.h 位于：c:\mysql-connector-c++-noinstall-1.1.0-win32\mysql-connector-c++-noinstall-1.1.0-win32\include\cppconn\config.h。双击它来调出它。现在只需注释掉所有应该只有 8 个的 typedef。将 libmysql.dll（在 Connector/C 内）和 mysqlcppconn.dll（在 Connector/C++ 内）放在编译器将构建输出到的文件夹中。完成后保存并运行。
旧帖子不要看
我已逐字按照此站点上的步骤操作：http ://blog.ulf-wendel.de/?p=215 但我仍然遇到编译错误。我对链接库或包含目录并不陌生，但我可以使用一个新的超级英雄，他使用 mysql connector/c++ 和 2010 express 制作了应用程序......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：我也遵循了这个： http://forums.mysql.com/read.php?167,492097,492097#msg- 492097我什至使用了 C++ 和 C 连接器（单独构建）以及每个测试64 位和 32 位版本（共 4 次测试）。我已经下载了boost并链接了它。我正在使用的新代码将在下面发布，它来自官方 mysql 网站。两个版本都会产生相同的错误。

更新 2：view_findpost_ p _1474626">http://www.dreamincode.net/forums/topic/253647-question-regarding-connecting-to-mysql-50-using-visual-studio-2010/page_view _findpost_ p _1474626这个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 int8_t 的#typedef。必须有一个解决方案。我什至会采用任何其他库（免费）可以连接到本地 MySQL 数据库，但我真的很想弄清楚这一点以帮助大家。
