Tom*_*ler 3 c++ mysql cmake mysql-connector visual-studio
我正在尝试在 Windows / Visual Studio 2015 上编译 MySQL Connector C++。我根据官方说明使用 CMake 生成了项目文件，效果很好。现在，当我尝试编译解决方案时，出现以下链接器错误：

经过几天的搜索和测试，我发现了问题所在。我很惊讶地发现这种情况从 2017 年甚至更早开始就一直在发生。
问题：
MySQL 网站上的文档令人困惑、过时且无用。
如果您正在下载最新的mysql-connector-c++-8.0.13-winx64.zip ，您将找到mysqlcppconn-static.lib库，该库大小为 64+ MB。您可以在项目中使用它，但是您还需要 .dll，并且它仅在发布版本中构建。
如果您想编译自己的连接器，只要您有“正确”的命令就可以这样做。您可以构建 x64 的静态调试版本以在您的应用程序中工作，并且不需要 .dll。
但是，根据发布的OP，您将遇到上述错误。问题是您需要手动链接mysqlclient.lib。在哪里可以找到它？因为在他们的下载页面中他们说：“Windows：客户端实用程序包可从 Windows 安装程序获得。” 这是错误的。哪有这回事。
您必须做的是转到：MySQL Connector/C（存档版本）并下载mysql-connector-c-6.1.11-winx64-debug.zip。一旦你有了这个，你就可以将它们链接到你的项目中：
#pragma comment(lib, "mysqlcppconn-static.lib")
#pragma comment(lib, "mysqlclient.lib") // mysql-connector-c-6.1.11-winx64\lib\vs14\debug
您的项目将在 Debug x64 和 VS2017 下编译并正常工作（就我而言）。
更多问题：
注意到我在哪里提到 Oracle 提供的 mysqlcppconn-static.lib 有 64+MB 吗？我之所以这么说是因为当你/我们构建自己的 mysql 连接器时，该库将只有大约 16 MB。
是的，Oracle 以某种方式链接了 1 个库中的所有内容。然而它是无用的，因为它处于发布状态并使用多线程 DLL (/MD)构建，因此如果您在调试模式下处理应用程序，它将无法编译，或者您将无法调试任何内容。
更多问题：
现在我们知道了如何在 x64 和 DEBUG 下构建这个 MySQL Connector，它仍然只能在多线程调试 DLL (/MDd)下工作。所以基本上你不能在 /MT 或 /MTd 下构建这个/你的应用程序。
构建当前 MySQL 连接器（他们称之为 JDBC）的步骤：
运行此命令（假设您需要静态调试）：
cmake -G "Visual Studio 15 2017 Win64" -DCMAKE_BUILD_TYPE=调试 -DBUILD_STATIC=true -DBUNDLE_DEPENDENCIES=ON -DSTATIC_MSVCRT=OFF -DWITH_JDBC=ON
完成后，通过mysql-connector-cpp-master\jdbc中的资源管理器，您将看到MYSQLCPPCONN.sln
从那里构建解决方案，您将在 mysql-connector-cpp-master\jdbc\driver\Debug中找到该库
现在就这些了，我希望我解决这个“谜团”的努力能够帮助别人。我真诚地希望 Oracle 开发人员能够醒悟并正确创建解决方案和文档，因为我们已经进入 2019 年了。
