在Go中运行简单的Qt GUI应用程序

Question

I am trying to modify following simple code from here to use Qt in Go.

#include <qapplication.h>
#include <qpushbutton.h>
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();
}

My Go (Golang) code is:

package main
import (
    "github.com/therecipe/qt"
    "github.com/therecipe/qt/widgets"
)
func main() {
    a := qt.NewQApplication(len(os.Args), os.Args) //ch: widgets.NewQ..
    hello := widgets.QPushButton( "Hello world!", 0 )
    a.setMainWidget( &hello )
    hello.Show()
    a.Exec()
}

However, I get following error:

# github.com/therecipe/qt/core
core.cpp:9:30: fatal error: QAbstractAnimation: No such file or directory
 #include <QAbstractAnimation>
                              ^
compilation terminated.

I have installed Qt bindings in Go using command:

go get "github.com/therecipe/qt"

I am working on Debian9 Linux and have following Qt4 packages installed:

libntrack-qt4-1         016-1.3         016-1.3         016-1.3         install

Where is the problem and how can it be solved? Thanks for your help.

Edit: For installing, I followed commands at https://github.com/therecipe/qt/wiki/Installation-on-Linux [Your system package managers version (without Android support)]. However, the command qtsetup gives following output with error:

$ sudo /home/abcde/go/bin/qtsetup
