我现在在做毕业设计，要做一个软件界面，里面有一个函数是用matlab语言写的，我已经可以再vs2010上调用matlab生成的dll了，但是Qt上没办法成功调用。希望大神指导下，谢谢！下面是我的代码
项目里面的代码：
QT += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = startButton
TEMPLATE = app
SOURCES += main.cpp\
widget.cpp
HEADERS += widget.h \
spot_simulationdll.h \
libspot_simulation.h
FORMS += widget.ui
OTHER_FILES +=
spot_simulationdll.lib
spot_simulationdll.dll
libspot_simulation.lib
libspot_simulation.dll
INCLUDEPATH += H:/matlab2011/extern/include
INCLUDEPATH += H:/matlab2011/extern/include/win32
LIBS+=-L H:/matlab2011/extern/lib/win32/microsoft -l libmx
LIBS+=-L H:/matlab2011/extern/lib/win32/microsoft -lmclmcrrt
LIBS+=-L H:/matlab2011/extern/lib/win32/microsoft -l mclmcr
cpp里面的代码：
#include "widget.h"
#include "ui_widget.h"
#include <QVBoxLayout>
#include <mclmcrrt.h>
#include <mclcppclass.h>
#include <QMessageBox>
#include <QLibrary>
#include <QMetaType>
#include <QDebug>
#include "spot_simulationdll.h"
Widget::Widget(QWidget *parent) :
QWidget(parent),
ui(new Ui::Widget)
{
startButton =new QPushButton(tr("start"));
connect(startButton,SIGNAL(clicked()),this,SLOT(startButtonSlots()));
QVBoxLayout *layout = new QVBoxLayout;
layout->addWidget(startButton);
setLayout(layout);
}
Widget::~Widget()
{
delete ui;
}
typedef void (*Fun)(void); //定义函数指针，以备调用
typedef bool (*Fun2)(void);
typedef bool (*Fun3)(void);
void Widget::startButtonSlots()
{
QLibrary lib("myfuncdll.dll");
QMessageBox msg;
if(lib.load())
{
QMessageBox::information(NULL,"OK","DLL load is OK!");
Fun open=(Fun)lib.resolve("_spot_simulation"); //援引 _mlfMyFunc() 函数
Fun2 init=(Fun2)lib.resolve("_spot_simulationdllInitialize");//援引 _myfuncdllInitialize() 函数
Fun2 termi=(Fun3)lib.resolve("_spot_simulationTerminate");//援引 _myfuncdllTerminate() 函数
if (open) //是否成功连接上 add() 函数
{
QMessageBox::information(NULL,"OK","Link to Function is OK!");
init(); //库初始化
//double _x[5] = {1, 2, 3, 4, 5}; //输入数组
// double _y[5]; //输出数组
// mxArray* x = mxCreateDoubleMatrix(1, 5, mxREAL);//创建1*5矩阵
// memcpy(mxGetPr(x), (void*)_x, sizeof(_x)); //拷贝输入数据
// mxArray* y = mxCreateDoubleMatrix(1, 5, mxREAL);//创建1*5矩阵
open();
// memcpy(_y, mxGetPr(y), sizeof(_y));//拷贝输出数据
// QString song=QString::number(_y[1]);
// QMessageBox::information(NULL,"OK",song);
termi();//结束DLL库
}
else
QMessageBox::information(NULL,"NO","Linke to Function is not OK!!!!");
}
else
QMessageBox::information(NULL,"NO","DLL is not loaded!");
}
出现的错误：
cannot find -lmclmcrrt
错误:cannot find H:/matlab2011/extern/lib/win32/microsoft: Permission denied
错误:cannot find -lmclmcr
错误:error: ld returned 1 exit status
