matlab - Read Mat Files in C++ in a Qt project -


i trying read mat-file in own mat_file_read.cpp in qt project, , having problems. error:

error lnk2019: unresolved external symbol matopen referenced in function "int __cdecl read_mat_file(class qstring)" (?read_mat_file@@yahvqstring@@@z)"

in project.pro, 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 header of cpp file:

#include <stdio.h> #include <stdlib.h> #include "mat.h" #include "matrix.h" #include <qstring> #include <qfiledialog>

in 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 curious thing qt editor recognizing functions "mat.h". suggesting me functions....

thanks in advance.

finally found solution, although don't understand fine why.... changed next lines in 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 working.... it's strange think, me it's ok. :)

thanks @suever support.
