Qt项目的通用Makefile

Question

I'm currently workind on a project for my school. It's a snake game which will work with 3 differents graphics.

It works fine, but I want to add a Qt touch in order to display a Window when the game is over. I already built the window, but now I need to merge this with my project, and my project has to compile with a Makefile. The problem is that I don't know if I can build my project with a unique Makefile. I usually use qmake -project, qmake, and make to build my Qt projects.

Thnks for your help

Answer 1

There is no universal Makefile , it will always vary depending on what platform you use, where Qt is installed, what Qt libraries you link and many other things.

For this simple main.cpp :

#include <QtGui>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QPushButton button("Hello");
    button.show();

    return app.exec();
}

Makefile could be:

CC=g++
CFLAGS=-I. -I/usr/include/qt4/QtGui -I/usr/include/qt4/QtCore -I/usr/include/qt4
LIBS=-lQtGui -lQtCore

app: main.cpp
    $(CC) $(CFLAGS) $(LIBS) $< -o $@

If you also need signals and slots, you need to add a separate target to Makefile to run moc . Try to investigate what qmake generates and learn from it.
