1、QT交叉环境说明

搭建环境需要准备1台Ubuntu 20.04的服务器，RK3588也是安装了Ubuntu20.04。RK3588安装Ubuntu的方法通过开发板厂商提供的系统烧录到开发板。
先描述服务器安装QT；
再描述服务器源码QT安装。

2、QT安装

在QT网站下载x86的版本，我基于自身安装的5.12.10版本来描述。如果需要该版本，也可以通过我的网盘提供给大家。

2.1 安装QT程序

将下载的qt-opensource-linux-x64-5.12.10.run放到\opt目录下。
采用如下命令安装。安装必须在本机安装，需要有界面。不能远程ssh登入安装。

./qt-opensource-linux-x64-5.12.10.run #	安装qt

2.2 安装交叉编译器和配置环境

1、通过网盘将编译器软件下载到opt
gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu.tar
gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf.tar
2、安装两个编译器

sudo tar -xvf gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu.tar 
sudo tar -xvf gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf.tar 

3、解压后

4、修改环境变量

sudo vim ~/.bashrc

添加交叉编译器环境，路径在:/opt/
PATH=$PATH:/opt/gcc-linaro-\mathrm{7.5.0}-2019.12-x86_6{4}_{a}arch64-linux-gnu/binPATH=$PATH:/opt/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin

# See /usr/share/doc/bash-doc/examples in the bash-doc package.

if [ -f ~/.bash_aliases ]; then
    . ~/.bash_aliases
fi
PATH=$PATH:/opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin
PATH=$PATH:/opt/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin

# enable programmable completion features (you don't need to enable

5、配置后使得全局变量生效，命令行输入

source ~/.bashrc

6、验证一下编译器是否已经安装好,命令行输入:

7、创建c程序进行验证
创建一个hello.c文件，程序如下：

vim hello.c

在vim编辑文件中，输入如下程序：

#include <stdio.h>
int main(int argc, char **argv)
{
    printf("Hello, you do it succeed!!!\n");
    return 0;
}

：wq!保存
8、对hello.c进行aarch64编译

 aarch64-linux-gnu-gcc hello.c -o helloworld

将生成可执行文件helloworld
9、将helloworld执行文件放到RK3588开发板进行执行

2.2 编译QT源码，配置交叉编译环境

1、在opt目录，对QT的源码包进行解压，输入:

sudo tar xvf qt-everywhere-src-5.12.10.tar.xz
cd qt-everywhere-src-5.12.10

2、进入到qtbase/mkspekcs/目录下，在该目录下，找到一个相似的工具链，cp一份并修改为指定的工具链（即在QT下添加自己的指定的平台）。然后输入:

sudo cp -a linux-aarch64-gnu-g++/ aarch64-linux-gnu-g++/
sudo cp linux-arm-gnueabi-g++/  linux-arm-rk3588-linux-g++/ -r 

3、进入到新建的目录aarch64-linux-gnu-g++文件夹下，修改qmake.conf的内容

sudo vim qmake.conf

4、将下面的内容添加进去

# modifications to g++.conf
QMAKE_CC                = /opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc 
QMAKE_CXX               = /opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-g++ 
QMAKE_LINK              = /opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-g++ 
QMAKE_LINK_SHLIB        = /opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-g++ 

# modifications to linux.conf
QMAKE_AR                = /opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-ar cqs
QMAKE_OBJCOPY           = /opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-objcopy
QMAKE_NM                = /opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc-nm  -P
QMAKE_STRIP             = /opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-strip
load(qt_config)

5、在源码解压的QT目录创建build目录，创建一个build.sh的文件

sudo mkdir build
cd build
sudo bim build.sh

将下面的代码放到build.sh文件中。

../configure \
-verbose \
-opensource \
-release \
-shared \
-confirm-license \
-make libs \
-nomake tests \
-nomake examples \
-skip qtmacextras \
-skip qtandroidextras \
-no-opengl \
-xplatform aarch64-linux-gnu-g++ \
-prefix /opt/qt-5.12.X-linux-aarch64-gcc

:wq!编辑后保存退出。build.sh设置可执行权限.

sudo chmod 777 build.sh

6、安装依赖库，尽量都安装上

基础的编译环境:
sudo apt-get build-dep qt5-default
sudo apt-get install libxcb-xinerama0-dev
sudo apt-get install build-essential perl python git
Libxcb:
sudo apt-get install ‘^libxcb.*-dev’ libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev libxkbcommon-dev libxkbcommon-x11-dev
OpenGL:
sudo apt-get install build-essential
sudo apt-get install libgl1-mesa-dev
sudo apt-get install libglu1-mesa-dev
sudo apt-get install libegl1-mesa-dev
sudo apt-get install freeglut3-dev
Qt WebKit:
sudo apt-get install flex bison gperf libicu-dev libxslt-dev ruby
Qt WebEngine:
sudo apt-get install libssl-dev libxcursor-dev libxcomposite-dev libxdamage-dev libxrandr-dev libdbus-1-dev libfontconfig1-dev libcap-dev libxtst-dev libpulse-dev libudev-dev libpci-dev libnss3-dev libasound2-dev libxss-dev libegl1-mesa-dev gperf bison
Qt Multimedia:
sudo apt-get install libasound2-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev
QDoc Documentation Generator Tool:
sudo apt install libclang-6.0-dev llvm-6.0

7、依赖库安装完成后，执行build.sh

sudo ./build.sh

8、执行make

sudo make

9、执行make install

sudo make install

在编译完成后执行 make install 会将qt库安装到 -prefix 指定的目录下。

10、配置交叉编译环境
（1）打开已经安装好2.1QT程序Qt5.12.10


双击打开qtcreator。

（2）配置其aarch64位编译器，在Compilers中点击Add我们之前安装并配置好的交叉编译链GCC，配置路径，名称要区别开
tools->option->kits



（3）在Qt Versions里面配置已经编译好的qmake，位置在opt下面

（4）添加Kit，配置如下图所示，Name可以自定义

（5）点击ok之后在Projects里点击刚配置好的Kits，然后选择我们的环境，选择Release模式，点击build即可

（6）Build之后显示绿色已经build成功

（7）看到已经build好的项目

（8）点击进去之后看到有一个可执行文件即可，拷贝到板子上就可以用了，根据不同的程序需要特殊的全局变量的设置，相关库lib的放置等，需要在home下.bashrc文件里添加，并且使用source生效即可
