解决方案:我决定为遇到相同问题的人制定一个分步指南。我不知道这是否完全解决了所有问题，但它确实让您可以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。这是为了帮助那些因尝试失败而几乎放弃的人，坦率地说，应该记录整个过程。抱歉发了这么长的帖子: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:c:\mysql-connector-c++-noinstall-1.1.0-win32\mysql-connector-c++-noinstall-1.1.0-win32\include\cppconn\config.h 的config.h。双击它来调出它。现在只需注释掉所有 typedef，那里应该只有 8 个。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内。完成后保存并运行。
旧帖不要看
我已逐字执行此站点上的步骤:http://blog.ulf-wendel.de/?p=215 但是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 super 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 (更改数据库)

更新:我也关注了这个: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 64 位和 32 位版本的两个测试(总共 4 个测试)。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 mysql 官方网站。两个构建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 这哥们好像觉得是因为config.h和stdint.h在compile时冲突，因为config.h里面有个# int8_t 的 typedef。必须有一个解决方案。我什至会使用任何其他可以连接到本地 MySQL 数据库的库(免费)，但我真的很想弄清楚这个问题以帮助大家。
最佳答案
因为有很多关于 C++ 和 MySQL 连接器的问题，而且很难让它工作，所以我会回答这个问题，即使这个问题是在 1 年前提出的。
解决方案很简单，您唯一需要做的就是在 cppcon/config.h 文件中注释所有 typedef
