Mir MYC-YT507 development board review: Development environment part 3: Qt tank game [Copy link]

 

Preface

This article uses a popular tank game implemented in Qt to experience the Qt development process of this development board, focusing mainly on the convenience of setting up the development environment from the perspective of secondary development.

Prepare

Refer to "Mil MYC-YT507 Development Board Evaluation: Development Environment Part 1: Linux C Key Control LED" to install the cross-compilation environment.

And basic login file transfer and other operations.

Install Qt development environment

Install the compilation environment

Download the data from http://down.myir-tech.com/MYD-YT507H/ in Windows, and unzip 03_Tools.zip

I unzipped it to E:\BOARD\MYC-YT507\03_Tools

Change the name of the folder Complie Toolchain to Complie_Toolchain because command line file names in Linux cannot have spaces.

wsl

cd ~

mkdir MYD-YT507H

cd MYD-YT507H/

Unzip the files under Windows directly into WSL

tar -xvf /mnt/e/BOARD/MYC-YT507/03_Tools/Complie_Toolchain/gcc-linaro-7.4.1-2019.02-x86_64_aarch64-linux-gnu-qt5.12.5-myir.tar.bz2 -C .

Install Qt Creator

Download QtCreator

wget https://mirrors.tuna.tsinghua.edu.cn/qt/development_releases/qtcreator/5.0/5.0.0-rc1/qt-creator-opensource-linux-x86_64-5.0.0-rc1.run

hint

Search find ../ -name libGLESv2.so

Find the path as

/home/lhj/MYD-YT507H/gcc-linaro-7.4.1-2019.02-x86_64_aarch64-linux-gnu/Qt_5.12.5/aarch64-buildroot-linux-gnu/sysroot/usr/lib/libGLESv2.so

Manually modify /home/lhj/MYD-YT507H/build-tanks-YT507H_dev_kit-Debug/Makefile. The content in the red box above is /home/lhj/MYD-YT507H/gcc-linaro-7.4.1-2019.02-x86_64_aarch64-linux-gnu/Qt_5.12.5/aarch64-buildroot-linux-gnu/sysroot/usr/lib/libGLESv2.so

The compiled code is located in

/home/lhj/MYD-YT507H/build-tanks-YT507H_dev_kit-Debug/Tanks

Export to Windows

cp /home/lhj/MYD-YT507H/build-tanks-YT507H_dev_kit-Debug/Tanks /mnt/e

Then import it to the development board.

run

ps check the process number of myapp2 and kill it

export QT_DEBUG_PLUGINS=1 enables debugging printing to facilitate problem analysis

./Tanks Run

If you print

./Tanks: error while loading shared libraries: libQt5Widgets.so.5: cannot open shared object file: No such file or directory

but:

export LD_LIBRARY_PATH=/usr/local/Qt_5.12.5/lib/:$LD_LIBRARY_PATH

Check here that the library path is /usr/local/Qt_5.12.5/ and the one referenced in the program is /usr/local/Qt-5.12.5/

So create a soft link

ln -s /usr/local/Qt_5.12.5/plugins/platforms/ /root/platforms

ln -s /usr/local/Qt_5.12.5 /usr/local/Qt-5.12.5

If you print

loaded library "/usr/local/Qt_5.12.5/plugins/egldeviceintegrations/libqeglfs-emu-integration.so"

EGL library doesn't support Emulator extensions

Aborted

but

export QT_QPA_EGLFS_INTEGRATION=none

If you print

QFontDatabase: Cannot find font directory /usr/local/Qt-5.12.5/lib/fonts.

Then soft link to the actual font file

ln -s /usr/local/Qt-5.12.5/fonts/ /usr/local/Qt-5.12.5/lib/fonts

Use USB mouse and keyboard to control

button

W: Forward

S: Back

A: Turn left

D: Turn right

Press buttons 1, 2, and 3 to select the firepower.

Press the q button to shoot.

Press s to pause and continue

Summarize

The development board supports Qt5.12, and the corresponding operating environment has been installed in the image. The SDK also provides a tool chain that can be used directly, so development is very convenient, and the relevant documents are also relatively detailed and developer-friendly.

refer to

MYD-YT507H_QT Application Development Notes.pdf

The development board supports many functions, and the host introduced it in detail.

Missing a package? You can search for errors on Baidu and usually find a solution.
