    上面的错误是由于程序中引用了多线程库,而默认使用单线程链接导致libcp.lib不能正确链接。那么解决它,只要改成对应的Multithread(/MT)多线程库就可以了。

    最后总结下/ML、/MT、/MD选项和库之间的对应关系,如下表:

    Note   Starting in Visual C++ 2005, LIBCP.LIB and LIBCPD.LIB (via the old /ML and /MLd options) have been removed. Use LIBCPMT.LIB and LIBCPMTD.LIB instead via the /MT and /MTd options.
    其中 /ML/MLd选项和libcp.lib、libcpd.lib库在Visual C++ 2005版编译器及后继续的版本中将被删除。取而代之的是/MT/MTd选项和libcpmt.lib、libcpmtd.lib引入库文件。

    解决方法:

    在使用得结构体其实是class __declspec(dllexport) Clibnetcomm,导致了问题所在,改为:

    #ifdef _NETCOMM
    #define COMM_API __declspec(dllexport)
    #else
    #define COMM_API __declspec(dllimport)
    #endif
        

    class COMM_API Clibnetcomm

    就完美解决。另外查了下区别,这个说的很详细https://www.cnblogs.com/zhehan54/p/5919983.html

    其实这个问题很简单,本来应该选择win32控制台应用程序,结果却选择了win32应用程序,就会导致这个问题。
    最简单的解决办法:重新建个工程,然后把类文件导入进去,或者直接新建类。
     
    下面是别人写的方法,未测试。
     
    =========================
     
     
    vc中error LNK2001:unresolved external symbol _WinMain@16的解决方法  一,问题描述error LNK2001: unresolved external symbol _WinMain@16
    debug/main.exe:fatal error LNK 1120:1 unresolved externals
    error executing link.exe;
    二,产生这个问题可能的原因1, 你用vc建了一个控制台程序,它的入口函数应该是main, 而你使用了WinMain.
    2.  你用vc打开了一个.c/.cpp 文件,然后直接编译这个文件,这个文件中使用了WinMian而不是main作为入口函数。vc这时的默认设置是针对控制台程序的。
    三, 解决方法1.进入project->setting->c/c++, 在category中选择preprocessor,在processor definitions中删除_CONSOLE, 添加_WINDOWS
    2.进入project->setting->Link, 在Project options中将 /subsystem:console改为/subsystem:windows.
    3.保存设置,Rebuild All.
