Qt TextToSpeech类出现“undefined reference to `_imp___ZN13QTextToSpeechC1EP7QObject'”错误
上代码
c++
#include "widget.h"
#include "ui_widget.h"
#include <QMessageBox>
#include <stdlib.h>
#include <QtTextToSpeech/QTextToSpeech>
Widget::Widget(QWidget *parent) :
QWidget(parent),
ui(new Ui::Widget)
{
ui->setupUi(this);
setWindowTitle("Lottery Machine");
QIntValidator *validator = new QIntValidator(0, 100, this);
ui->mine->setValidator(validator);
ui->maxe->setValidator(validator);
}
Widget::~Widget()
{
delete ui;
}
void Widget::on_quib_clicked()
{
close();
}
void Widget::on_genb_clicked()
{
int mi=ui->mine->text().toInt();
int ma=ui->maxe->text().toInt();
int r=mi+rand()%(ma-mi+1)-49;
char rc=r+'0';
QMessageBox::information(this, tr("Generate"),tr("Number %1.").arg(rc+1),QMessageBox::Ok,QMessageBox::NoButton);
}
void Widget::on_gas_clicked()
{
QTextToSpeech *speech;
speech=new QTextToSpeech;
int mi=ui->mine->text().toInt();
int ma=ui->maxe->text().toInt();
int r=mi+rand()%(ma-mi+1)-49;
char rc=r+'0';
const char *lc=&rc;
speech->say(lc);
}
```
运行结果及报错内容

我的解答思路和尝试过的方法
尝试只引用QTextToSpeech头文件
