我正在尝试在Windows / Visual Studio 2015上编译MySQL Connector C ++。 我根据official instructions使用CMake生成了项目文件，工作正常。现在，当我尝试编译解决方案时，我收到以下链接器错误：

万一你不想算数：其中有64个。我注意到，我已经安装了64位版本的C ++连接器源和32位版本的C连接器，所以我安装了C Connector 64bits，链接器错误正好加倍（128）。
所以我卸载了两者并安装了两者的32位版本，只是为了回到上面看到的错误。
我知道那些有同样问题的人有很多问题，但我要么找不到可以帮助我的问题，要么就找不到问题。
如果你能指出我的方法，那就太好了。
感谢您的时间
答案 0 :(得分：2)
经过几天的搜索和测试，我发现了问题。我很惊讶地看到这种情况自2017年甚至更早开始。
问题：
MySQL网站上的文档令人困惑，过时且无用。
如果要下载最新的 mysql-connector-c ++-8.0.13-winx64.zip ，则会找到 mysqlcppconn-static.lib 库，该库为64 + MB。您可以在项目BUT中使用它，也将需要.dll，并且该文件仅在发行版中构建。
如果要编译自己的连接器，则仅具有“正确”命令即可。您可以构建x64的STATIC DEBUG版本以在您的应用程序中工作，而无需.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 。在哪里找到它？因为在他们的下载页面中，他们说：“ Windows：可从Windows Installer获得客户端实用程序包。”这是错误的。没有这样的东西。
您必须执行的操作是转到MySQL Connector/C (Archived Versions)并下载 mysql-connector-c-6.1.11-winx64-debug.zip 。一旦有了这个，就可以在项目中链接它们：
#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（对于我而言）下编译并正常工作。
更多问题：
提到我提到Oracle提供的mysqlcppconn-static.lib有64 + MB的地方？我之所以这样说，是因为当您/我们建立自己的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lib中的所有内容。但是，它没有用，因为它在Release中并使用多线程DLL（/ MD）构建，因此，如果您在Debug模式下处理应用程序，它将无法编译，否则将无法调试任何东西。
更多问题：
现在，我们发现了如何在x64和DEBUG下构建此MySQL连接器，它仍然仅在多线程调试DLL（/ MDd）下工作。因此，基本上，您不能在/ MT或/ MTd下构建此/您的应用。
建立当前MySQL连接器（称为JDBC）的步骤：
运行此命令（假设您要使用STATIC DEBUG）：
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 中的资源管理器进入 您将看到 MYSQLCPPCONN.sln
从那里开始构建解决方案，您将在其中找到lib mysql-connector-cpp-master \ jdbc \ driver \ Debug
仅此而已，我希望我为解决这一“谜团”所做的努力将对某人有所帮助。我衷心希望Oracle开发人员能够唤醒我们，并在2019年正式创建解决方案和文档。
答案 1 :(得分：1)
“我根据官方说明使用CMake生成了项目文件，工作正常。”
我认为你的意思是CMake成功生成了项目，但项目编译不正确。
您是否检查了哪些二进制文件当前与失败的项目相关联？如果没有，我建议右键点击解决方案资源管理器中的项目 - ＆gt;属性 - ＆gt;接头
如果CMake缓存了包含所需二进制文件的某些目录，请转到CMake - ＆gt;文件标签 - ＆gt;删除缓存，然后重新生成项目。
我能想到的另一件事是检查包含MySQL二进制文件路径的环境变量。如果某些内容已更改为环境变量，则可能需要重新运行CMake，清除其缓存并重新生成项目。
如果您确定要链接二进制文件，则可能存在某些启用静态链接的宏。我不记得是否是MySQL连接器的情况，但这只是想到的另一件事。
