【瑞芯微】【rk3128】【移植 qt 5.12.9】

一、移植 QT 5.12.9

1. 源码下载

qt5.12.9源码下载

2. 配置 QT

进入 rk3128 docker 环境

复制代码

./rk3128_docker_env/init.sh

c 复制代码

进入已存在的开发环境...
my_rk3128_dev
developer@c8aa26115a95:/workspace$ vim /home/developer/.bashrc

c 复制代码

ARM_BIN_PATH=/workspace/RK3128/buildroot/output/rockchip_rk312x/host/bin
export PATH=$ARM_BIN_PATH:$PATH

c 复制代码

developer@c8aa26115a95:/workspace/qt-everywhere-src-5.12.9$ vim qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf


MAKEFILE_GENERATOR      = UNIX
CONFIG                 += incremental
QMAKE_INCREMENTAL_STYLE = sublib

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

# modifications to g++.conf  修改为 buildroot 里面的 交叉工具链
QMAKE_CC                = arm-buildroot-linux-gnueabihf-gcc
QMAKE_CXX               = arm-buildroot-linux-gnueabihf-g++
QMAKE_LINK              = arm-buildroot-linux-gnueabihf-g++
QMAKE_LINK_SHLIB        = arm-buildroot-linux-gnueabihf-g++

# modifications to linux.conf
QMAKE_AR                = arm-buildroot-linux-gnueabihf-ar cqs
QMAKE_OBJCOPY           = arm-buildroot-linux-gnueabihf-objcopy
QMAKE_NM                = arm-buildroot-linux-gnueabihf-nm -P
QMAKE_STRIP             = arm-buildroot-linux-gnueabihf-strip
load(qt_config)

进入qt-everywhere-src-5.12.9文件夹下配置一个编辑文件名字可以自己命名

shell 复制代码

cd qt-everywhere-src-5.12.9
gedit autoconfigure.sh

c 复制代码

Note: Also available for Linux: linux-clang linux-icc

Note: -optimized-tools is not useful in -release mode.

WARNING: Cross compiling without sysroot. Disabling pkg-config

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/workspace/qt-everywhere-src-5.12.9/arm-qt'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

3. 编译安装

c 复制代码

# 直接在 当前目录执行

make

make install  # 最终将 编译后的 QT 生成到 /workspace/qt-everywhere-src-5.12.9/arm-qt 目录下

4. 放到板子里

将上面编译出来的 arm-qt 放到我们的板子里面就可以了

c 复制代码

cp -r arm-qt/ /usr/lib/

在板子里面更新环境变量

c 复制代码

vi /etc/profile

export QT_ROOT=/usr/lib/arm-qt
export QT_QPA_FONTDIR=/usr/share/fonts
export QT_QPA_PLATFORM_PLUGIN_PATH=$QT_ROOT/plugins
export QT_QPA_PLATFORM=linuxfb:tty=/dev/fb0
export QT_PLUGIN_PATH=$QT_ROOT/plugins
export LD_LIBRARY_PATH=$QT_ROOT/lib:$QT_ROOT/plugins/platforms
export QML2_IMPORT_PATH=$QT_ROOT/qml
export QT_QPA_FB_TSLIB=1
