Qt build时出现cont find lsqlite3

#include "mainwindow.h"
#include <QApplication>

#include <QtCore/QCoreApplication>
#include <QtSql>
#include <QDebug>

int main(int argc, char *argv[])
{
    //QApplication a(argc, argv);

    QCoreApplication a(argc, argv);
    QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE");
    db.setDatabaseName("/tmp/my.db");
    if (!db.open())
    {
        qDebug()<<"open database failed ---"<<db.lastError().text()<<"/n";
        return -1;
    }
    QSqlQuery query;
    bool ok = query.exec("CREATE TABLE IF NOT EXISTS  people (id INTEGER PRIMARY KEY AUTOINCREMENT,"
                         "name VARCHAR(20) NOT NULL,"
                         "age INTEGER NULL)");
    if (ok)
    {
        qDebug()<<"ceate table partition success/n";
    }
    else
    {
        qDebug()<<"ceate table partition failed/n";
    }
    for (int i = 0; i< 3; ++i)
    {
        query.prepare("INSERT INTO people (id, name, age) VALUES (:id, :name, :age)");
        query.bindValue(":name", QString("smith_%1").arg(i+1));
        query.bindValue(":age", 20+i*5);
        query.exec();
    }

    query.exec("SELECT id, name, age FROM people");
    while (query.next())
    {
        qDebug()<<"people("<<query.value(0).toInt()<<")  name:"<<query.value(1).toString()<<"  age:"<<query.value(2).toInt();
    }

    MainWindow w;
    w.show();
   
    return a.exec();

.pro文件内容：

QT       += core gui
QT       += core sql
QT       -= gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = sqlite
TARGET = sql
CONFIG += console

你有安装sql吗?
找不到lsqlite3啊 sqlite是Qt内置的，只要启用sql模块即可直接使用，发布程序的时候带上dll。 应该下载一个好一些的Qt版本，会有sqlite3的。此外第二个错误是因为第一个错误引起的。
