poco 切换到 MT 链接错误 Visual Studio 2019

如何解决poco 切换到 MT 链接错误 Visual Studio 2019

我无法在我已经创建的项目中运行 POCO。我用示例 Websocket 做了一个新项目，试图将它配置为成功构建 => 应用程序能够启动和工作。但是当我尝试使用 OpenCV 在我的另一个项目中实施相同的步骤时，我遇到了很多错误。

我用于构建两个项目的代码：

#define POCO_STATIC
#include "pocoWebSocket.h"

#include <iostream>
#include <string>
using namespace std;

int main(int argc,char** argv)
{
    std::cout << std::endl<< "I am alive!" << std::endl;
    WebSocketServer app;
    std::cout << "app run" << std::endl;
    return app.run(argc,argv);
    //visit http://localhost:9980
}

项目设置为：

• C/C++/代码生成/运行时库：/MT
• C/C++ / General / Additional Include Directories: C:\src\POCO\Foundation\include;C:\src\POCO\Net\include;C:\src\POCO\Util\include;%(AdditionalIncludeDirectories)

在链接器中：

• 一般/附加库目录： C:\src\POCO\buildMT\lib\Debug;C:\src\POCO\buildMT\lib\Release;%(AdditionalLibraryDirectories)
• 输入/附加依赖项： crypt32.lib ws2_32.lib iphlpapi.lib PocoNetmt.lib PocoFoundationmt.lib

当我用 OpenCV 对项目做同样的事情时，我会得到这些错误：有什么建议吗？

解决方法

C:\Program Files (x86)\Windows Kits\10\Include\10.0.18362.0\shared\windef.h(190,3):

186: typedef struct tagSIZE
187: {
188:    LONG        cx;
189:    LONG        cy;
190: } SIZE,*PSIZE,*LPSIZE;
     ^ ^
     1 3

在您的代码或使用的库中的某处，定义了冲突的宏 SIZE。

,

有人给了我很大的耳光...当我教我的朋友如何编码时，我不小心定义了 SIZE 和其他东西，并意外地将它保存到我的解决方案中....我还不得不评论一些更多的东西来制作它起作用了。

感谢你们给我的小推动，谢谢。

这是我必须编辑的文件，评论的文件没有评论，config.h：
