在Qt项目中阅读C ++中的Mat文件 [英] Read Mat Files in C++ in a Qt project

问题描述

我想在一个自己的mat_file_read.cpp在一个Qt项目中读取一个mat文件，我有问题。我的错误：

 错误lnk2019：未解析的外部符号matOpen在函数int __cdecl read_mat_file（class QString）（？read_mat_file @ @YAHVQString @@@ Z）
  

在我的project.pro中，我包括：

  INCLUDEPATH + = C：\Program Files\MATLAB\MATLAB Production Server\R2015a\extern\include\ 
 LIBS + = -LC：\Program Files\MATLAB\MATLAB Production Server\R2015a\bin\win64 
 -llibmx 
 -llibmat 
 -llibeng 
  

在我的cpp文件的标题中：

  #include< stdio.h> 
 #include< stdlib.h> 
 #includemat.h
 #includematrix.h 
 #include< QString> 
 #include< QFileDialog> 
  

在我的mat_file_reader.cpp：

  #includeread_mat_file.h
 int read_mat_file（QString file）
 {
 
 //变量定义
 int result; 
 MATFile * pmat; 
 
 if（file.isEmpty（））return 0; 
 QByteArray ba = file.toLatin1（）; 
 const char * rootFile = ba.data（）; 
 pmat = matOpen（rootFile，r）; 
 
 result = 0; 
 
 return（result == 0）？EXIT_SUCCESS：EXIT_FAILURE; 
 
} 
  

奇怪的是，Qt编辑器正在识别函数从mat.h。

解决方案

最后我找到一个解决方案，虽然我不明白为什么....我只改变了我的project.pro的Qt的下一行：

  INCLUDEPATH + = C：\Program Files\MATLAB\MATLAB生产服务器\R2015a\extern\include\ 
 LIBS + = -llibmx  - LC：\librerias\matlab\extern\lib\win64\microsoft 
 LIBS + = -llibmat -LC：\librerias\matlab\extern\lib\win64\microsoft 
 LIBS + = -llibeng -LC：\librerias\matlab\extern\lib\win64\microsoft 
  

现在它工作....这很奇怪，我想，但对我来说没关系。 ：）

感谢@Suever的支持。

I am trying to read a mat-file in an own mat_file_read.cpp in a Qt project, and I am having problems. My error:

error lnk2019: unresolved external symbol matOpen referenced in function "int __cdecl read_mat_file(class QString)" (?read_mat_file@@YAHVQString@@@Z)"

In my project.pro, I am including:

INCLUDEPATH += C:\Program Files\MATLAB\MATLAB Production Server\R2015a\extern\include\
LIBS += -LC:\Program Files\MATLAB\MATLAB Production Server\R2015a\bin\win64
        -llibmx
        -llibmat
        -llibeng

In the header of my cpp file:

#include <stdio.h>
#include <stdlib.h>
#include "mat.h"
#include "matrix.h"
#include <QString>
#include <QFileDialog>

In my mat_file_reader.cpp:

#include "read_mat_file.h"
int read_mat_file(QString file)
{

    // Variable definition
    int result;
    MATFile *pmat;

    if (file.isEmpty()) return 0;
    QByteArray ba = file.toLatin1();
    const char *rootFile = ba.data();
    pmat = matOpen(rootFile,"r");

    result = 0;

  return (result==0)?EXIT_SUCCESS:EXIT_FAILURE;

}

And the curious thing is the Qt editor is recognizing the functions from "mat.h". It is suggesting me the functions....

Thanks so much in advance.

解决方案

Finally I found a solution, although I don't understand fine why.... I only changed the next lines in my project.pro of Qt:

INCLUDEPATH += C:\Program Files\MATLAB\MATLAB Production Server\R2015a\extern\include\
LIBS += -llibmx -LC:\librerias\matlab\extern\lib\win64\microsoft
LIBS += -llibmat -LC:\librerias\matlab\extern\lib\win64\microsoft
LIBS += -llibeng -LC:\librerias\matlab\extern\lib\win64\microsoft

Now it is working.... It's strange I think, but for me It's ok. :)

Thanks so much @Suever for the support.
