海思Hi3516DV300 QT移植详解_专栏

1.qt的选择与下载

wget http://download.qt.io/archive/qt/5.12/5.12.8/single/qt-everywhere-src-5.12.8.tar.xz tar xf qt-everywhere-src-5.12.8.tar.xz

2.创建海思的qmake.conf

cp /opt/qt-everywhere-src-5.12.8/qtbase/mkspecs/linux-arm-gnueabi-g++/ /opt/qteverywhere-src-5.12.8/qtbase/mkspecs/arm-himix200-linux-g++ -rf
vi /opt/qt-everywhere-src-5.12.8/qtbase/mkspecs/arm-himix200-linux-g++/qmake.conf

qmake.conf内容修改如下:

#
# qmake configuration for building with arm-linux-gnueabi-g++
#
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
QMAKE_CC = arm-himix200-linux-gcc
QMAKE_CXX = arm-himix200-linux-g++
QMAKE_LINK = arm-himix200-linux-g++
QMAKE_LINK_SHLIB = arm-himix200-linux-g++
# modifications to linux.conf
QMAKE_AR = arm-himix200-linux-ar cqs
QMAKE_OBJCOPY = arm-himix200-linux-objcopy
QMAKE_STRIP = arm-himix200-linux-strip
load(qt_config)
# modifications to gcc-base.conf
QMAKE_CFLAGS_RELEASE += -mcpu=cortex-a7 -mfloat-abi=softfp -mfpu=neon-vfpv4
QMAKE_CXXFLAGS_RELEASE += -mcpu=cortex-a7 -mfloat-abi=softfp -mfpu=neon-vfpv4 -
fpermissive

3.开始编译

./configure -prefix ../qt5.12.8_hi3516dv300 -opensource -confirm-license -release -strip
-no-eglfs -linuxfb -qt-zlib -no-gif -qt-libpng -qt-libjpeg -qt-freetype -no-rpath -no-pch

重新生成liblinuxfb.so库

…/…/…/…/bin/qmake
make

将qt-everywhere-src-5.12.8/qtbase/plugins/platforms/下生成的libqlinuxfb.so拷贝到安装目录下plugins/platforms/下，替换原有liblinuxfb.so

5.编译demo

cd /opt/qt-everywhere-src-5.12.8/qtbase/examples/widgets/graphicsview/collidingmice
../../../../bin/qmake make

6.运行demo

1)打包编译好的qt
tar -czvf qt5.12.8_hi3516dv300.tgz qt5.12.8_hi3516dv300
将qt5.12.8_hi3516dv300.tgz拷贝到板端并解压
将编译好的collidingmice拷贝到板端

2)环境变量配置

export QT_QPA_PLATFORM_PLUGIN_PATH=/nfsroot/qt5.12.8_hi3516dv300/plugins
export QT_QPA_FONTDIR=/nfsroot/qt5.12.8_hi3516dv300/fonts
export QWS_MOUSE_PROTO="tslib:/dev/input/mice mouseman:/dev/input/mice"
export LD_LIBRARY_PATH=/nfsroot/qt5.12.8_hi3516dv300/lib:LD_LIBRARY_PATH
export QT_QPA_PLATFORM=linuxfb:tty=/dev/fb0
export
QT_QPA_PLATFORM=linuxfb:fb=/dev/fb0:size=800x1280:offset=0x0:nographicsmodeswitch
