#include <QtCore/QCoreApplication>

int main(int argc, char *argv[])
{
	QCoreApplication a(argc, argv);

	return a.exec();
}

위를 기반으로 제작한다.

추가로 Visual Studio로 만들다 보니 링크에러가 많이 발생하여 그냥 Qt Creator로 진행한다...

추가로 프로젝트파일(.pro)에 QT += widgets를 추가해줘야한다.

QT -= gui
QT += widgets

CONFIG += c++11 console
CONFIG -= app_bundle

# The following define makes your compiler emit warnings if you use
# any Qt feature that has been marked deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS

# You can also make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0

SOURCES += \
        main.cpp

# Default rules for deployment.
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

Visual Studio에서 빌드하기

Qt Modules에 widgets을 추가한다.
