[问题]新立得里面的QT4是怎么装的？帮我一下阿libqt4-core qt4-designer qt4-dev-t

wth123456 · #1

我在新立得里面安装了下面几个包
libqt4-core
qt4-designer
qt4-dev-tools
qt4-qtconfig
libqt4-dev
libqt4-gui libqt4-debug
libqt4-sql
可是在编译的时候通不过。
我的程序是QT4的

代码：全选

#include <QApplication>
#include <QLabel>
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QLabel *label = new QLabel("Hello QT!");
    label->show();
    return app.exec();
}

代码：全选

qmake  -project
qmake
make

前两步都没有问题，但是make的时候出了一大堆错

代码：全选

我怎么觉得应该用G++而不是GCC呢

大概就是这个原因造成那几个宏不能处理吧

gothicane · #3

还是从QT官网上下源码自己编译吧

我觉得也应该用G++ 但是Makefile是qmake自动生成的,在windows下面也是这样用的.
