Yuzuki Lizard 全志V851S开发板 –移植 QT5.12.9教程

移植 QT5 教程 （此教程基于docker版V851S开发环境）

docker pull registry.cn-hangzhou.aliyuncs.com/gloomyghost/yuzukilizard

编译依赖

apt-get install repo git gcc-arm-linux-gnueabihf u-boot-tools device-tree-compiler mtools \
parted libudev-dev libusb-1.0-0-dev python-linaro-image-tools linaro-image-tools libssl-dev \

libc6:i386 texinfo liblz4-tool genext2fs expect autoconf intltool libqt4-dev libgtk2.0-dev

安装第一遍会有报错，部分无法执行。在执行一遍，就可以了。

1.建议新建一个docker避免环境污染的问题。

2.打开下面目录

/root/tina-v853-docker/platform/thirdparty/gui/qt/

并解压

tar -xvf qt-5.12.9.tar.xz

3.导入编译工具链

3.1 新建tool文件夹

mkdir /root/tool

3.2 将toolchain.tar解压到tool文件夹下面

cd /root/tool/
tar -xvf toolchain.tar

4.source 编译工具链

4.1 修改profile

vi /etc/profile

增加一行代码

export PATH=$PATH:/root/tool/toolchain/bin

4.2 增加环境变量

nano /root/.bashrc

增加二行代码

export PATH=$PATH:/root/tool/toolchain/bin
export STAGING_DIR=$STAGING_DIR:/root/tool/toolchain/bin

5.qt解压完成后，进入文件夹

cd /root/tina-v853-docker/platform/thirdparty/gui/qt/qt-5.12.9/

在当前文件夹里面创建一个.sh文件 执行

touch make.sh
chmod 777 make.sh
nano make.sh

复制粘贴下面内容到文件里面

#!/bin/sh
PWD=`pwd`
    mkdir arm-qt
    ./configure \
    -prefix $PWD/arm-qt \
    -release \
    -opensource \
    -shared \
    -xplatform linux-arm-gnueabi-g++ \
    -optimized-qmake \
    -pch \
    -qt-sqlite \
    -qt-libjpeg \
    -qt-libpng \
    -qt-zlib \
    -no-opengl \
    -skip qt3d \
    -skip qtcanvas3d \
    -skip qtpurchasing \
    -skip qtlocation \
    -skip qttools \
    -no-sse2 \
    -no-openssl \
    -no-cups \
    -no-glib \
    -no-dbus \
    -no-xcb \
    -no-iconv \
    -no-separate-debug-info \
    -no-fontconfig \
    -recheck-all \
    -make examples

    make -j16 
    make install

这里面比较复杂，里面开启和关闭部分项目是为了保证编译可以成功。

如果需要编译复杂的QT可以自己测试。

6.将工具链改为自己的

执行：

nano /root/tina-v853-docker/platform/thirdparty/gui/qt/qt-5.12.9/qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf
#
# qmake configuration for building with arm-linux-gnueabi-g++
#

MAKEFILE_GENERATOR      = UNIX
CONFIG                 += incremental
QMAKE_INCREMENTAL_STYLE = sublib

include(../common/linux.conf)
include(../common/gcc-base-unix.conf)
include(../common/g++-unix.conf)

CROSS_COMPILE=arm-openwrt-linux

# modifications to g++.conf
QMAKE_CC                = $${CROSS_COMPILE}-gcc
QMAKE_CXX               = $${CROSS_COMPILE}-g++
QMAKE_LINK              = $${CROSS_COMPILE}-g++
QMAKE_LINK_SHLIB        = $${CROSS_COMPILE}-g++

# modifications to linux.conf
QMAKE_AR                = $${CROSS_COMPILE}-ar cqs
QMAKE_OBJCOPY           = $${CROSS_COMPILE}-objcopy
QMAKE_NM                = $${CROSS_COMPILE}-nm -P
QMAKE_STRIP             = $${CROSS_COMPILE}-strip
load(qt_config)

7.编译QT5

执行：

cd /root/tina-v853-docker/platform/thirdparty/gui/qt/qt-5.12.9/

执行：

./make.sh

8.安装

如果没有报错，就编译完成了。

make install

9.下载build文件

执行：

tar -cvf arm-qt.tar arm-qt

压缩包压缩好，就可以通过ftp下载下来了。

10.编译qtdemo

10.1 编译qtdemo 创建一个文件夹helloworld，然后再文件夹里面创建一个文件 main.cpp

#include <QApplication>
#include <QWidget>
#include <QLabel>
#include <QSlider>
#include <QHBoxLayout>
 
int main(int argc, char **argv)
{
 QApplication app(argc, argv);
 QWidget *window  = new QWidget;
 window->setWindowTitle("I am a slider");
 
 QLabel *label = new QLabel;  // QLabel控件，用于显示数字
 QSlider *slider = new QSlider(Qt::Horizontal);  // 滑动条
 slider->setRange(0, 100);
 
 QObject::connect(slider, SIGNAL(valueChanged(int)), label, SLOT(setNum(int)));
 slider->setValue(50);
 
 QHBoxLayout *layout = new QHBoxLayout; //level 
 layout->addWidget(label);
 layout->addWidget(slider);
 window->setLayout(layout);
 
 window->resize(400, 240);
 
 window->show();
 
 return app.exec();
}

10.2 编译 执行：

/root/tina-v853-docker/platform/thirdparty/gui/qt/qt-5.12.9/arm-qt/bin/qmake -project

执行：

/root/tina-v853-docker/platform/thirdparty/gui/qt/qt-5.12.9/arm-qt/bin/qmake

执行：

make

此时会提示报错：修改.pro结尾的文件，末尾增加一行代码。

参考这个代码

######################################################################
# Automatically generated by qmake (3.1) Sun Apr 2 23:32:59 2023
######################################################################

TEMPLATE = app
TARGET = helloworld
INCLUDEPATH += .

# The following define makes your compiler warn you 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

# Input
SOURCES += hello.cpp



greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

并重新执行一遍

10.3 下载可执行文件 helloworld

11.导入

/root/tina-v853-docker/platform/thirdparty/gui/qt/qt-5.12.9/arm-qt/bin

下面的两个文件夹到板子上，其余的不用

复制bin下面的lib 到usr/lib 并根据报错相应的修改文件名 复制bin下面的plugin到usr目录下面 复制刚才的可执行文件helloworld 到/mnt

12.进入板子/mnt

添加权限 chmod 777 helloworld 执行

./helloworld

13.此时会报错，要修改文件名

凡是涉及到5.12.9.so的文件名，全部要改成5.so 否则会报错 （如何快速改文件名呢？） 其中包含名字为core,gui,widget的，一定要改
