Ubuntu 12.04 LTS

Qt版本：

$qmake -v
QMake version 2.01a
Using Qt version 4.8.1 in /usr/lib/x86_64-linux-gnu

.pro文件：

TEMPLATE += app
QT += core gui declarative
SOURCES += qtCppIntegration.cpp

.cpp文件：

#include <QApplication>
#include <QQuickView>
#include <QUrl>

int main (int argc,char *argv[])
{
  QApplication app(argc,argv);
  QQuickView view;
  view.setSource(QUrl("/home/...plesQtQuickQML/anchors.qml"));
  view.show();
  return app.exec();
}

错误：

$make
g++ -c -m64 -pipe -O2 -Wall -W -D_REENTRANT -DQT_NO_DEBUG -DQT_DECLARATIVE_LIB -DQT_GUI_LIB -DQT_CORE_LIB -I/usr/share/qt4/mkspecs/linux-g++-64 -I. -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtGui -I/usr/include/qt4/QtDeclarative -I/usr/include/qt4 -I. -o qtCppIntegration.o qtCppIntegration.cpp
qtCppIntegration.cpp:1:24: fatal error: QApplication: No such file or directory
compilation terminated.
make: *** [qtCppIntegration.o] Error 1

这样就可以了：

sudo apt-get install libqt4-dev
