为什么我的QT程序不能运行？（在线等！）
我的程序如下： #include <QApplication>
#include <QPushButton>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QPushButton hello("hello QT!");
hello.resize(100,30);
hello.show();
return app.exec();
}


编译过程:qmake -project
qmake
make
我用的不是交叉编译，Makefile内容如下：#############################################################################
# Makefile for building: qt
# Generated by qmake (2.01a) (Qt 4.4.0-rc1) on: Sun Jan 4 10:27:27 2009

编译完成后生成44.o文件，在linux下输入: ./44.o
结果为： cannot execute binary file

哪位达人能为我解惑啊？100分只送达人！

[解决办法]
44.o 是 object 文件，需要经过 link 才能成为可执行文件

qmake 执行一般是源码的当前目录

lz 确定没有生成 qt 这个文件


[解决办法]
.o 是目标文件,你应该执行./qt,这才是可执行文件
qmake -project hello.pro
qmake -o Makefile hello.pro
make
./hello
还有你是在arm平台下运行的吗
