0. 准备工作

0.1 WSL安装Qt5.15.2

运行代码

wget https://download.qt.io/official_releases/online_installers/qt-unified-linux-x64-online.run
chmod 777 qt-unified-linux-x64-online.run
sudo ./qt-unified-linux-x64-online.run

然后会出现经典QT安装目录，按照Qt安装提示即可，版本选择Qt5.15.2

如果出现network error 运行 sudo ./qt-unified-linux-x64-online.run --mirror https://mirrors.tuna.tsinghua.edu.cn/qt

0.2 WSL 安装交叉编译工具

将atk-dlrk3568-toolchain-arm-buildroot-linux-gnueabihf-x86_64-20230921-v1.0.1.run 文件拷贝到WSL上
然后运行指令：

sudo chmod 777 atk-dlrk3568-toolchain-arm-buildroot-linux-gnueabihf-x86_64-20230921-v1.0.1.run
sudo ./atk-dlrk3568-toolchain-arm-buildroot-linux-gnueabihf-x86_64-20230921-v1.0.1.run

默认安装到：/opt/atk-dlrk356x-toolchain/ 路径中。
我们要使用其中的编译器和调试器GDB。
具体来说：
GCC：/opt/atk-dlrk356x-toolchain/bin/aarch64-buildroot-linux-gnu-gcc
G++：/opt/atk-dlrk356x-toolchain/bin/aarch64-buildroot-linux-gnu-g++
GDB：\opt\atk-dlrk356x-toolchain\bin\aarch64-linux-gdb

0.3 WSL升级Cmake

在WSL中升级Cmake，在WSL中运行

sudo apt remove cmake -y
sudo apt update
sudo apt install cmake

这时，你会惊奇的发现安装的还是camke 3.16.3，这是ubuntu20.04支持的cmake最高版本就是3.16.3。怎么解决这个问题呢？可以修改CMakeList.txt文件第一行

cmake_minimum_required(VERSION 3.16)

支持详情如下：

Ubuntu 16.04 ships with cmake-3.5.1
Ubuntu 17.10 ships with cmake-3.9.1
Ubuntu 18.04 ships with cmake-3.10.2
Ubuntu 20.04 ships with cmake-3.16.3
Ubuntu 21.04 ships with cmake-3.18.4

0.4 WSL 安装GDB

如果在Debugger中出现找不到WSL GDB错误时，请在WSL中安装GDB，运行

sudo apt install gdb

0.5 WSL安装libgl1-mesa-dev

sudo apt-get install libgl1-mesa-dev

1. 创建Qt项目

如图所示，创建一个QtRemoteDemo项目

然后设置本地ToolSet

运行程序，确保Cmake配置正确

如图，程序是可以运行的。

2. 配置Clion WSL 编译

配置WSL 工具链

配置如图所示。

这时，Cmake会报错：

设置WSL为默认工具链

Clion右上角 Add Configuration,如图所示

配置结果如图所示

这时，即可运行程序，WSL是可以显示GUI窗体的，如图所示

3. 配置Clion WSL 交叉编译

嵌入式开发中，交叉编译是必须的，。如果仅开发与硬件无关的GUI，还可以暂时无需交叉编译器。但RK3568有很多硬件外设，所以还是要配置交叉编译的

新增一个Tool Chain 如下图所示，命名为WSL-Cross

设置ToolSet 为WSL-Cross，如下图所示

4. 配置RK3568 部署调试

新增Remote GDB Server，如图所示

然后点击右上角Debug按钮，得到如下错误

解决方法：配置环境变量

QT_QPA_PLATFORM=wayland
XDG_RUNTIME_DIR=/var/run/

5. Cmake文件

cmake_minimum_required(VERSION 3.16)
project(QtRemote)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_AUTOUIC ON)

set(CMAKE_PREFIX_PATH  "/opt/atk-dlrk356x-toolchain/aarch64-buildroot-linux-gnu/sysroot/usr/lib/cmake/")

find_package(Qt5 COMPONENTS
        Core
        Gui
        Widgets
        REQUIRED
        PATHS "/opt/atk-dlrk356x-toolchain/aarch64-buildroot-linux-gnu/sysroot/usr/lib/"
)

add_executable(QtRemote main.cpp)
target_link_libraries(QtRemote
        Qt5::Core
        Qt5::Gui
        Qt5::Widgets
)

if (WIN32 AND NOT DEFINED CMAKE_TOOLCHAIN_FILE)
    set(DEBUG_SUFFIX)
    if (MSVC AND CMAKE_BUILD_TYPE MATCHES "Debug")
        set(DEBUG_SUFFIX "d")
    endif ()
    set(QT_INSTALL_PATH "${CMAKE_PREFIX_PATH}")
    if (NOT EXISTS "${QT_INSTALL_PATH}/bin")
        set(QT_INSTALL_PATH "${QT_INSTALL_PATH}/..")
        if (NOT EXISTS "${QT_INSTALL_PATH}/bin")
            set(QT_INSTALL_PATH "${QT_INSTALL_PATH}/..")
        endif ()
    endif ()
    if (EXISTS "${QT_INSTALL_PATH}/plugins/platforms/qwindows${DEBUG_SUFFIX}.dll")
        add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD
                COMMAND ${CMAKE_COMMAND} -E make_directory
                "$<TARGET_FILE_DIR:${PROJECT_NAME}>/plugins/platforms/")
        add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD
                COMMAND ${CMAKE_COMMAND} -E copy
                "${QT_INSTALL_PATH}/plugins/platforms/qwindows${DEBUG_SUFFIX}.dll"
                "$<TARGET_FILE_DIR:${PROJECT_NAME}>/plugins/platforms/")
    endif ()
    foreach (QT_LIB Core Gui Widgets)
        add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD
                COMMAND ${CMAKE_COMMAND} -E copy
                "${QT_INSTALL_PATH}/bin/Qt5${QT_LIB}${DEBUG_SUFFIX}.dll"
                "$<TARGET_FILE_DIR:${PROJECT_NAME}>")
    endforeach (QT_LIB)
endif ()

6. 设置自启脚本

默认的自启应用 /etc/init.d/S50QDesktop
该脚本内容

# Provides:          qdesktop
# Required-Start:    mountvirtfs
# Required-Stop:
# Should-Start:
# Should-Stop:
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Qt desktop
### END INIT INFO

PATH="/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin"

# Load default env variables from profiles(e.g. /etc/profile.d/qdesktop.sh)
. /etc/profile

start_qdesktop()
{
        # Wait for weston ready
        [ "${QT_QPA_PLATFORM}" == wayland ] && \
                while [ ! -e ${XDG_RUNTIME_DIR}/wayland-0 ]; do
                        sleep .1
                done

    wayland-info | grep "logical_width: 1080" > /dev/null
    if [ $? -eq 0 ]; then
        /opt/apps/1080p/QDesktop > /dev/null 2>&1 &
    else
        /opt/apps/720p/QDesktop > /dev/null 2>&1 &
    fi
}

stop_qdesktop()
{
        killall QDesktop
}

case "$1" in
        start)
                echo -n "starting qdesktop... "
                start_qdesktop
                echo "done."
                ;;
        stop)
                echo -n "stoping qdesktop... "
                stop_qdesktop
                echo "done."
                ;;
        restart|reload)
                echo -n "stoping qdesktop... "
                stop_qdesktop && sleep .3
                echo "done."

                echo -n "starting qdesktop... "
                start_qdesktop
                echo "done."
                ;;
        *)
                echo "Usage: $0 {start|stop|restart}"
                exit 1
esac

exit 0

把以上内容改成自己的程序即可
