I am developing a small application using QWidget and statically binding Qt 5.6. I am using VS12 at the moment.
#include <QMainWindow>
#include <QApplication>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QMainWindow w;
w.show();
return a.exec();
}
It compiles fine, but I get linker errors.

I have included the following libraries:
winmm.lib
imm32.lib
Ws2_32.lib
opengl32.lib
Qt5Guid.lib
Qt5Widgetsd.lib
qtpcred.lib
qtharfbuzzngd.lib
Qt5PlatformSupportd.lib
qwindowsd.lib
libEGLd.lib
libGLESv2d.lib
qtfreetyped.lib
Qt5Cored.lib
And the funny thing is that if you use QtCreator, it compiles, links and works just fine. I have seen QtCreator add the following compiled flags:
-DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -DQT_OPENGL_ES_2 -DQT_OPENGL_ES_2_ANGLE -DQT_OPENGL_ES_2_ANGLE_STATIC -DGL_APICALL= -DEGLAPI=
I tried them in my project, but did not change anything. What am I missing? What do I need to communicate with the program?
