Qt与Matlab混合编程

Question

当我使用Qt和MATLAB混合编程时，我有一个问题。我测试了一个示例，但它失败了。这是我的代码。首先是我的职业档案：

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = paintertest
TEMPLATE = app


SOURCES += main.cpp\
        mainwindow.cpp \
    test1.cpp

HEADERS  += mainwindow.h \
    test1.h \
    mat.h \
    matrix.h \
    mclbase.h \
    mclcppclass.h \
    mclmcr.h \
    mclmcrrt.h \
    tmwtypes.h \
    MyAdde.h \
    engine.h

FORMS    += mainwindow.ui

接下来是我的mainwindow.h：

#include <QMainWindow>
#include <QPainter>
#include "test1.h"
#include <QVariant>
#include <armadillo>
#include <iostream>
#include "sigpack.h"
#include "MyAdde.h"
#include "mat.h"
#include "matrix.h"
#include "mclbase.h"
#include "mclcppclass.h"
#include "mclmcr.h"
#include "mclmcrrt.h"
#include "tmwtypes.h"
#include "engine.h"

接下来是我的mainwindow.cpp：

 double a=6;
    double b = 9;
    double c;
    if(MyAddeInitialize()){
        qDebug()<<"ok";
    }
    mwArray mwA(1, 1, mxDOUBLE_CLASS);
    mwArray mwB(1, 1, mxDOUBLE_CLASS);
    mwArray mwC(1, 1, mxDOUBLE_CLASS);
    mwA.SetData(&a, 1);
    mwB.SetData(&b, 1);
    MyAdde(1, mwC, mwA, mwB);
    c = mwC.Get(1, 1);
    cout<<"c"<<c;
    MyAddeTerminate();
    mclTerminateApplication();

MyAdde.h/MyAdde.dll/MyAdde.lib是我的Matlab代码。下面是我的Matlab代码：

 function [ c ] = MyAdde( a, b )
 c = a+b;
 end

我使用MATLAB生成MyAdde.h/MyAdde.dll/MyAdde.lib，并将此文件添加到我的Qt pro file.But some error happened.This is my Qt error：

C:\Users\Administrator\Desktop\Qt\paintertest\mainwindow.cpp:23: error: undefined reference to `MyAdde(int, mwArray&, mwArray const&, mwArray const&)'

我检查了MyAdde.h，发现了以下代码：

 extern LIB_MyAdde_CPP_API void MW_CALL_CONV MyAdde(int nargout, mwArray& c, const mwArray& a, const mwArray& b);

我认为这个问题是由const mwArray&和mwArray const&引起的。我不明白其中的原因。我需要你的帮助!

Answer 1

这是一个链接器错误，所以它编译得很好，但链接失败

可能是这些东西错了

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/./ -lMyAdde
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/./ -lMyAdde
else:unix: LIBS += -L$$PWD/./ -lMyAdde

你想要达到什么目的？如果具有MyAdde dll的调试版本和发布版本，则第一行和第二行通常不应相同。
