一. 环境准备
1.下载qt5源码Open Source Development | Open Source License | Qt 或者从v851s sdk 中获取
路径tina-v853-docker/platform/thirdparty/gui/qt/qt-5.12.9.tar.xz 2. 编译环境vmware虚拟机安装的ubuntu22.10
3. 交叉编译工具v851s sdk 中的toolchain
路径tina-v853-docker/prebuilt/rootfsbuilt/arm/toolchain-sunxi-musl-gcc-830 4. ubuntu下需要安装的依赖库
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 \
autotools-dev libsigsegv2 m4 libdrm-dev curl sed make binutils build-essential gcc g bash \
patch gzip bzip2 perl tar cpio python unzip rsync file bc wget libncurses5 libglib2.0-dev \
openssh-client lib32stdc6 gcc-aarch64-linux-gnu libncurses5-dev lzop libssl1.0.0 libssl-dev \
libglade2-dev cvs mercurial subversion asciidoc w3m dblatex graphviz python-matplotlib \
libc6:i386 texinfo liblz4-tool genext2fs expect autoconf intltool libqt4-dev libgtk2.0-dev
二. 解压qt5源码进行编译
1. 在 ubuntu 的 home/xxx/ 下创建一个qt5 的文件解压qt5 源码
tar -xvf qt-xxx.tar.xz
2. 将交叉编译工具放到 ubuntu 的home/xxx/ 采用绝对路径的方式调用交叉编译工具 3. 在qt5 源码根目录下创建 build.sh 写入编译规则 并且给权限
touch build.sh
chmod 777 build.sh在 build.sh 中写入编译规则
#!/bin/sh
PWDpwdmkdir 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 examplesmake -j16 make install 4. 配置交叉编译工具路径qt5源码根目录下打开文件qmake.conf
gedit 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 sublibinclude(../common/linux.conf)
include(../common/gcc-base-unix.conf)
include(../common/g-unix.conf)#一定要是你 toolchain 的绝对路径不要写错
#CROSS_COMPILEarm-openwrt-linux
#CROSS_COMPILE/home/navy/v851s/Yuzukilizard/toolchain/toolchain-sunxi-musl-gcc-830/toolchain/bin/arm-openwrt-linux
CROSS_COMPILE/home/navy/v851s/Yuzukilizard/toolchain/gcc-linaro-5.3.1-2016.05-x86_64_arm-linux-gnueabi/bin/arm-linux-gnueabi# modifications to g.conf

QMAKE_OBJCOPY $${CROSS_COMPILE}-objcopy
QMAKE_NM $${CROSS_COMPILE}-nm -P
QMAKE_STRIP $${CROSS_COMPILE}-strip
load(qt_config)
5. 编译并安装产生库文件 在qt5 源码根目录下执行
./build.sh 执行
make install 将会在qt5 根目录arm-qt 文件中产生所有的qt5 的库文件将其下载到嵌入式开发版中即可。 三. 编写qtDemo 进行测试
1. 在 ubuntu home/xxx/ 中创建qtDemo 文件夹并且创建两个文件helloworld.cpp 和 helloworld.pro
mkdir qtDemo
touch helloworld.cpp
touch helloworld.pro
在 helloworld.cpp 中写入
#include QApplication
#include QWidget
#include QLabel
#include QSlider
#include QHBoxLayoutint 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();
}
在 helloworld.pro 中写入

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_BEFORE0x060000 # disables all the APIs deprecated before Qt 6.0.0# Input
SOURCES helloworld.cppgreaterThan(QT_MAJOR_VERSION, 4): QT widgets
2. 通过编译出来的qt5 对demo 进行测试
在qt源码目录下执行
arm-qt/bin/qmake -project
arm-qt/bin/qmake
arm-qt/bin/qmake helloworld.cpp将产生的二进制文件helloworld 下载到嵌入式开发板给权限执行./helloworld 即可。
chmod 777 helloworld
./helloworld ******* 如果提示库文件出错请将xxx5.12.9.so 库文件名均改成xxx5.so
