Mysql connector/C++for windows 2010 express未编译

解决方案：我决定为有相同问题的人做一个循序渐进的指南。我不知道这是否完全修复了所有问题，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，请评论，以便我可以修复它们。这是为了帮助那些在尝试失败后大多放弃的人，坦率地说，整个过程都应该记录在案。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:

=

您应该会得到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\cppcon\config.h。双击它以打开它。现在只需注释掉所有的typedef，应该只有8个。将libmysql.dllinside和mysqlcppconn.dllinside放置在编译器将生成输出到的文件夹中。完成后保存并运行

老帖子不好看

我在本网站上一字不差地遵循了以下步骤： 但我仍然得到一个编译错误。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。。。举个简单的吻的例子。我一整天都在磨牙。 示例来源：数据库已更改

        std::cout<<e.what();
    }

    int a;      // hang
    cin >> a;

    return 0;
}

Update：我也遵循了：我甚至使用C++和C连接器，分别与每个64个测试和32位版本进行了单独的构建，共有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发布在下面，它来自mysql官方网站。两个版本都会产生相同的错误

谢谢你的帮助

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。必须有一个解决办法。我甚至会把任何其他图书馆的免费连接到本地MySQL数据库，但我真的很想找出这一点来帮助大家。< /P> < P>由于C++和MySQL连接器存在很多问题，而且很难使它工作，所以我甚至会在1年前提出这个问题。

解决方案非常简单，您只需对cppcon/config.h文件中的所有typedef进行注释

是否尝试向libmysql.lib添加额外的库依赖项？你可以从这里下载：是的。这是我第二次尝试让它工作。第二次我输了。62位不工作的原因是输出的复制粘贴？微软有人写了这样一个不正确的声明，我并不感到惊讶，但我想知道。。。为什么你的问题从解决方案开始？如果你有一个有效的答案，那么你应该为自己的问题写一个答案。
