请大家给看下啊:
我在red hat 9下写了个小程序,代码如下:
#include
#include
int main( int argc, char **argv )
{
QApplication a( argc, argv );
QPushButton helloworld( "Hello world!", 0 );
helloworld.resize( 100, 30 );
a.setMainWidget( &helloworld );
helloworld.show();
int result = a.exec();
return result;
}
环境变量也设置了,
然后执行了以下命令:
progen -n helloworld -o helloworld.pro
tmake helloworld.pro -o Makefile
make
结果出现了如下的错误提示信息:
g++ -c -pipe -DQWS -fno-exceptions -fno-rtti -Wall -W -O2 -DNO_DEBUG

问题已经解决，自己上来给个答案吧，把Makefile文件里的Link项改为g++
