Qt对象不在Ubuntu 14.04中运行

Question

I have an application (to test) in Qt4 to start learning, but I can't even execute the object I created. First of all, the Qt version I have is:

user@ubuntu:~/m_work/tests/qt1$ qmake --version
QMake version 2.01a
Using Qt version 4.8.6 in /usr/lib/x86_64-linux-gnu

Same output if I run the command qmake-qt4 --version

I have a file called main.cpp with this content:

#include <QApplication>
#include <QPushButton>

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

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

   return app.exec();
}

The commands I execute to compile are:

qmake -project
qmake
make
chmod 755 main.o
./main

And the error I get after the last command:

bash: ./main.o: cannot execute binary file: Exec format error

The architecture of my laptop is x64, so as far as I know, it should work.

Hope you have some information you could tell me!
