yesterday I download and install QT-5.3 on my linux(ubuntukylin),today I try to compile my first QT-project.
I write the code by VIM like like this :
#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();
}
I save this file when I finished , and the file’s path is /home/jxf/TestQt
then commond:
cd /home/jxf/TestQt
qmake -project
qmake TestQt.pro
so far,everything is going well
when I used last commond : make
the system tell me,“fatal error: QApplication: No such file or directory”,
then I try to find answer in inter,and someone tell me put “QT += widgets” in TestQt.pro.
I do like this and compile again,but system tell me “fatal error: Qlabel: No such file or directory” this time,
others in inernet tell me modify source code file,
#include<QtWidgets/QLabel> replace #include<QLabel>,
but when I make ,system still tell me fatal error: Qlabel: No such file or directory
How can I do….
