How to display console window for debugging?

[smp12345]

Qtdeploy default compiler - H = windowsgui already hidden DOS window, won't cause some print output, should be how to operate according to the DOS window, please?I use QML, and the sample program uses the official example

package main

import (
    "fmt"
    "os"

    "github.com/therecipe/qt/core"
    "github.com/therecipe/qt/quick"
    "github.com/therecipe/qt/widgets"
)

func init() {
    ItemTemplate_QmlRegisterType2("CustomQmlTypes", 1, 0, "ItemTemplate")
}

type ItemTemplate struct {
    quick.QQuickItem

    _ string `property:"someString"`

    _ func(bool, []bool)                                                `signal:"sendBool,auto"`
    _ func(int, []int)                                                  `signal:"sendInt,auto"`
    _ func(float32)                                                     `signal:"sendFloat,auto"`
    _ func(float64, []float64)                                          `signal:"sendDouble,auto"`
    _ func(string, []string)                                            `signal:"sendString,auto"`
    _ func(error, []error)                                              `signal:"sendError,auto"`
    _ func(*core.QVariant, []*core.QVariant, map[string]*core.QVariant) `signal:"sendVariantListMap,auto"`
    _ func(*ItemTemplate, []*ItemTemplate)                              `signal:"sendItemTemplate,auto"`
    _ func(*quick.QQuickItem, []*quick.QQuickItem)                      `signal:"sendItem,auto"`
    _ func(*core.QObject, []*core.QObject)                              `signal:"sendObject,auto"`
    //...
}

func (t *ItemTemplate) sendBool(a bool, b []bool) {
    fmt.Println("sendBool:", a, b)  //This line will not output properly because there is no DOS window
}

func main() {
    core.QCoreApplication_SetAttribute(core.Qt__AA_EnableHighDpiScaling, true)
    app := widgets.NewQApplication(len(os.Args), os.Args)
    view := quick.NewQQuickView(nil)
    view.SetTitle("bridge Example")
    view.SetResizeMode(quick.QQuickView__SizeRootObjectToView)
    view.SetSource(core.NewQUrl3("qrc:/qml/main.qml", 0))
    view.Show()

    app.Exec()
}

Because there is no DOS window, this line cannot be output normally. How to add compilation options or other ways to display DOS window

func (t *ItemTemplate) sendBool(a bool, b []bool) {
    fmt.Println("sendBool:", a, b)  //This line will not output properly because there is no DOS window
}
