[total n00b]QGLWidgets keeps giving LNK2001 error in visual studio 2013??
-
sorry if my question is too noobish ,but really i have tried almost everything, my main point was to get some opengl code running in visual studio and study of "opengl programming guide" , i am trying for 2nd day now, with no luck....
i have everything set up ,added the include folder , the lib folder also copied the bin folder to the debug folder , i ran an empty QApplication and it worked , now i don't know why this doesn't work
My main:
@#include"QtWidgets\qapplication.h"
#include"Screen.h"int main(int argc, char* argv[]){
QApplication app(argc, argv);
Screen s;
s.show();
return app.exec();
}
@The Screen class header , screen.cpp is empty:
@
#pragma once
#ifndef SCREEN
#define SCREEN
#include <QtOpenGL\qglWidget>
class Screen : public QGLWidget
{
public:
void initializeGL();
void paintGL();
};
#endif
@i just want to show the opengl window , and apparently i cant even do that
here is a LNK error
@
Error 1 error LNK2019: unresolved external symbol "__declspec(dllimport) public: __cdecl QGLWidget::QGLWidget(class QWidget *,class QGLWidget const *,class QFlags<enum Qt::WindowType>)" (_imp??0QGLWidget@@QEAA@PEAVQWidget@@PEBV0@V?$QFlags@W4WindowType@Qt@@@@@Z) referenced in function "public: __cdecl Screen::Screen(void)" (??0Screen@@QEAA@XZ) D:\OpenGL\c++\firstOpen\tmain.obj firstOpen

it is basically 25 of those!! -
Hi, welcome to devnet.
OpenGL support is a separate module in Qt. You need to tell linker where to look for it.
Add this to your .pro file:
@
QT += opengl
@Edit: Oh, and re-run qmake after that.
