c++ - 无法构建 MySQL++ 库 -- mysqlpp_d.dll 链接错误

Question

我正在尝试通过 Visual Studio 2013 (MSVC-12.0) 在 Windows 中构建 MySQL++ 库。这就是我所做的：

• 通过“完整安装”安装在我的计算机MySQL Community Server 5.6.16
• 下载mysql++-3.2.1，解压
• 通过 Visual Studio 2013 从目录“mysql++-3.2.1\vc2005\”打开一个名为“mysql++.sln”的文件（不幸的是，这个库没有 Visual Studio 2013 的本机解决方案），转换它
• “附加包含目录”（在我的例子中是“e:\software\MySQL\MySQL Connector C 6.1.3\include\”）和“附加库目录”（“e:\software\MySQL\MySQL 连接器”中的更改路径C 6.1.3\lib\") 中的“mysqlpp”项目设置
• 试图构建这个项目——“mysqlpp_d.lib”构建成功，而“mysqlpp_d.dll”的构建给了我以下错误：
