Cmake 运行连接器c+时出现疯狂错误+；程序

我的连接器/C++有问题。 我使用CYON作为IDE，希望创建一个C++程序来与MySQL数据库进行交互。 这是我的CMakeList.txt文件，其中包括c++/connector静态和动态库：

cmake_minimum_required(VERSION 3.15)
project(cpp_programming)

set(CMAKE_CXX_STANDARD 20)
set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(MYSQL_CPPCONN_DIR "C:/Program Files/MySQL/MySQL Connector C++ 8.0")

include_directories(${PROJECT_NAME} PUBLIC ${MYSQL_CPPCONN_DIR}/include)
add_executable(${PROJECT_NAME} main.cpp)

# Static Libraries
target_link_libraries(${PROJECT_NAME} ${MYSQL_CPPCONN_DIR}/lib64/vs14/libcrypto.lib)
target_link_libraries(${PROJECT_NAME} ${MYSQL_CPPCONN_DIR}/lib64/vs14/libssl.lib)
target_link_libraries(${PROJECT_NAME} ${MYSQL_CPPCONN_DIR}/lib64/vs14/mysqlcppconn.lib)
target_link_libraries(${PROJECT_NAME} ${MYSQL_CPPCONN_DIR}/lib64/vs14/mysqlcppconn8.lib)
target_link_libraries(${PROJECT_NAME} ${MYSQL_CPPCONN_DIR}/lib64/vs14/mysqlcppconn8-static.lib)
target_link_libraries(${PROJECT_NAME} ${MYSQL_CPPCONN_DIR}/lib64/vs14/mysqlcppconn-static.lib)

# Dynamic Link Libraries
target_link_libraries(${PROJECT_NAME} ${PROJECT_SOURCE_DIR}/libcrypto-1_1-x64.dll)
target_link_libraries(${PROJECT_NAME} ${PROJECT_SOURCE_DIR}/libssl-1_1-x64.dll)
target_link_libraries(${PROJECT_NAME} ${PROJECT_SOURCE_DIR}/mysqlcppconn-7-vs14.dll)
target_link_libraries(${PROJECT_NAME} ${PROJECT_SOURCE_DIR}/mysqlcppconn8-2-vs14.dll)

<>我在我的C++源文件中只包括xDava.h头：

#include <iostream>
#include <mysqlx/xdevapi.h>

using namespace std;

int main()
{
    return 0;
}

链接dll文件或静态文件时是否出错

你有什么建议

请帮帮我，这会给我带来很多麻烦

这里有几个问题

您不需要链接所有这些不同的库。您实际上只需要链接一个

mysqlcppconn

库。若要定位库，请尝试使用，并将其用于链接。您的CMake文件应简化为以下内容：

我不确定您是否正在使用

ssl

和

crypto

库，因此如果需要，请将它们添加回

您的库（VisualC++）与您正在使用的编译器（MinGW）不匹配。据我所知，MySQL连接器C++没有提供一套明文库；它们只提供使用VisualStudio编译器构建的库。因此，您需要切换到使用VisualC++编译器来使用这些库。另一种选择是下载MySQL源代码，并尝试使用MinGW构建它，但这可能更困难

希望这有帮助

欢迎来到Stackoverflow！不鼓励发布代码或日志消息的链接。请在您的问题帖子中以文本形式发布完整的错误消息。此外，我不确定您是否需要链接所有这些不同的库。对于mysqlcppconn库，请尝试仅链接此库：

lib64/vs14/mysqlcppconn.lib

。谢谢，我这样做了，但再次收到上面的错误。上面的错误是什么。图像被切断，我们无法看到错误消息的有用部分。请将错误消息作为文本而不是图像添加到问题帖子中。您好，已编辑。。。。。
