控制台编译过程

1.在win10开始菜单找到以下内容，点击打开控制台

2.切换到项目所在目录

其中我的项目整体结构如下：

3.写好项目的pro文件，例如，我这个项目的pro文件如下所示：

#-------------------------------------------------
#
# Project created by QtCreator 2019-04-22T16:13:03
#
#-------------------------------------------------

QT       += core gui sql network multimedia

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = QQ
TEMPLATE = app

# The following define makes your compiler emit warnings if you use
# any feature of Qt which has been marked as deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS

# You can also make your code fail to compile if you use deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0

CONFIG += c++11

HEADERS += 
    mainui.h 
    leftbar.h 
    database.h 
    clientsocket.h 
    settingswnd.h

SOURCES += 
    main.cpp 
    mainui.cpp 
    leftbar.cpp 
    database.cpp 
    clientsocket.cpp 
    settingswnd.cpp

# Default rules for deployment.
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

RESOURCES += 
    resource/login_ui/login_ui.qrc 
    qss.qrc 
    icons.qrc

RC_ICONS = exe.ico #exe图标文件

include($$PWD/basewidget/basewidget.pri)
include($$PWD/cell/cell.pri)
include($$PWD/comapi/comapi.pri)
include($$PWD/login/login.pri)
include($$PWD/midbar/midbar.pri)
include($$PWD/rightbar/rightbar.pri)
include($$PWD/titlebar/titlebar.pri)

DESTDIR         = $$PWD/release/QQ
#OBJECTS_DIR     = $$PWD/release/obj
#MOC_DIR         = $$PWD/release/moc
#UI_DIR          = $$PWD/release/ui
#RCC_DIR         = $$PWD/release/rcc

4.在刚才的控制台执行以下命令
qmake QQ.pro

这时候控制台输出如下：

可以观察到，项目文件夹中多了以下文件:

5.接下来我们用mingw对刚刚生成的makefile执行make操作，该过程使用以下命令：
mingw32-make

由于我的项目比较大，所以这个过程执行时间较长（花了3分钟）。
在编译过程中，输出了很多warning，但是没有error，所以就是编译成功。

可以看到，编译完成之后，在release目录下生成了exe文件，如下所示：

这个生成exe文件的目录是在刚才那个pro文件中指定的，如下所示：
DESTDIR = $$PWD/release/QQ

6.接下来我们双击这个exe文件，发现报错，原因是缺少相应的dll文件。

控制台打包发布过程

1.在刚才我们那个控制台切换到生成的exe文件的目录下，使用以下命令自动打包：
windeployqt QQ.exe

控制台输出如下信息：

接着我们可以看到原来QQ.exe目录下多了很多dll文件，如下所示：

现在我们再双击这个exe文件试试

我们发现，exe已经能打开了。
