MATLAB CREATE DLL：命令 'link' 以 return 值“1”退出

Question

问题：想在 LABVIEW 中使用 MATLAB DLL

问题：低于错误

我试过了：https://forums.ni.com/t5/Example-Code/Walkthrough-for-Creating-a-MATLAB-DLL-That-Can-Be-Called-in/ta-p/3882891?profile.language=en

创建 DLL 文件并在 Labview 中使用它

这是我的 exampleScript.m 文件

function [sumone]=exampleScript(arr)
sumone=arr+1;
end

我用这个命令创建了DLL文件

mcc -v -B csharedlib:exampleScript exampleScript.m

并且如 doc 中所写，

This is not a native C type, which is what LabVIEW knows how to interface with. LabVIEW does not
know what to do with these types, which will pose problems for us later.

所以他们说要使用这个命令

mbuild -v exampleWrapper.c exampleScript.lib LINKFLAGS="$LINKFLAGS /DLL
/DEF:exampleWrapper.def" LDEXT=".dll"" CMDLINE250="mt -outputresource:$EXE';'2 -
manifest $MANIFEST"

同时创建 3 个新文件 exampleWrapper.C、exampleWrapper.h、exampleWrapper.def exampleWrapper.c

#include<stdio.h>
#include "exampleScript.h"
void loadExampleScript(void) {
    exampleScriptInitialize();
}
void unloadExampleScript(void) {
    exampleScriptTerminate();
}
int wmlfExampleScript(double* c2dArray, int numRows, int numColumns){
    int nargout=1;
    int result=1;
    mxArray *mIn2dArray;
    mxArray *mOut2Array=NULL;
    mIn2dArray=mxCreateDoubleMatrix(numRows, numColumns, mxREAL);
    memcpy(mxGetPr(mIn2dArray), c2dArray, numRows*numColumns*sizeof(double));
    result=mlfExampleScript(nargout, &mOut2Array, mIn2dArray);
    memcpy(c2dArray, mxGetPr(mOut2Array), numRows*numColumns*sizeof(double));
    mxDestroyArray(mIn2dArray);
    mxDestroyArray(mOut2Array);
    
    return result;
}

exampleWrapper.h

void loadExampleScript(void);
void unloadExampleScript(void);
int wmlfExampleScript(double* c2dArray, int numRows, int numColumns);

exampleWrapper.def

LIBRARY exampleWrapper
EXPORTS
loadExampleScript
unloadExampleScript
wmlfExampleScript

Answer 1

运行它在一行中解决了这个问题

mbuild -v exampleWrapper.c exampleScript.lib LINKFLAGS="$LINKFLAGS /DLL /DEF:exampleWrapper.def" LDEXT=".dll" CMDLINE250="mt -outputresource:$EXE';'2 -manifest $MANIFEST"
