内容:
我刚开始学习QT,第一个程序就是"Hello,word,"但在编译时出现了问题,请各位指导~~
源代码:(照抄的)
#include
#include
int main(int argc,char **argv)
{
QApplication a(argc,argv);
QPushButton hello("Hello,world!",0);
hello.resize(100,30);
a.setMainWidget(&hello);
hello.show();
return a.exec();
}
编译过程:
# qmake -project
# qmake
# make
前两步都没问题,当执行make时出险错误,如下:
......................

你的Qt库设置的不对
#2 [qzqstar 02-25 01:17]
那应该怎么改讷? 谢谢啦!~~~

你要先说你在哪个系统下用?Window ORLinux
用什么编译器?VC OR Mingw
还有你的QT库设置对不对?
最好你去参考一下这个版面置顶的资料

你试一下下面的编译命令
qmake -project
qmake file.pro -o Makefile
make
