编译C dll部署MATLAB代码时出现C2371错误

Error C2371 when compiling C dll deployment MATLAB code

我正在尝试使用VS2010与MATLAB 2007b编译C dll。我得到这个错误:

c:program filesmicrosoft visual studio 10.0vcincludeyvals.h(576): error C2371: 'char16_t' : redefinition; different basic types
c:program filesmatlabr2007bexternincludematrix.h(336) : see declaration of 'char16_t'

代码如下:

#include <stdio.h>

#include "..OpenCV_Lib.h"

#define Outlist plhs[1]

        for( i = 0; i < imnn; i ++ )
            imno[i] = (int)dimno[i];
        LookBigOrder( mem, imno, pref, Rm, Rn );
    }
    class memlist mem2 = LookBigOrder( mem, gnum );
    Rm = mem2.GetEntrysize()-1;
    if( nlhs >= 2 ){
        Outlist = mxCreateDoubleMatrix( Rm, 2, mxREAL );
        double * l = mxGetPr( Outlist );
        for( i = 0; i < Rm; i ++ )
            l[i] = mem2.GetSize( i );
        for( i = 0; i < Rm; i ++ )
            l[i+Rm] = mem2.GetIndex(mem2.GetSize( Rm ))[i];

        double * l = mxGetPr( r );

            l[j] = mem2.GetIndex(i)[j];
        mxSetCell( Out, i, r );
    }
    mem.free();
    mem2.free();
}

我已经尝试了几种方法来寻找解决办法，但还没有找到解决这个问题的方法。

我该如何解决这个问题?

谢谢!

char16_t可能是由Matlab和c++标准库同时定义的。

当包含C库时，而不是

#include <stdlib.h>

使用

#include <cstdlib>

。我把。h去掉，在前面加一个c。

这应该把它们的内容放入std命名空间，允许您选择您想要的
