s5p4418 qt5.7.1移植与虚拟键盘修改

Posted 2021-05-20 红尘六欲

以下是s5p4418上qt5.7.1的移植记录,下载qt5.7.1源码qt-everywhere-opensource-src-5.7.1.tar.gz这个可以去官方网站下载.

修改qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf,修改为如下:

 

#
# qmake configuration for building with arm-cortex_a9-linux-gnueabi-g++
#

MAKEFILE_GENERATOR      = UNIX
CONFIG                 += incremental
QMAKE_INCREMENTAL_STYLE = sublib

#QT_QPA_DEFAULT_PLATFORM = linux
QT_QPA_DEFAULT_PLATFORM = eglfs
QMAKE_CFLAGS_RELEASE += -O2 -march=armv7-a -mcpu=cortex-a9
QMAKE_CXXFLAGS_RELEASE += -O2 -march=armv7-a -mcpu=cortex-a9

include(../common/linux.conf)
include(../common/gcc-base-unix.conf)
include(../common/g++-unix.conf)
include(./opengl.conf)
# modifications to g++.conf
QMAKE_CC                = arm-cortex_a9-linux-gnueabi-gcc
QMAKE_CXX               = arm-cortex_a9-linux-gnueabi-g++
QMAKE_LINK              = arm-cortex_a9-linux-gnueabi-g++
QMAKE_LINK_SHLIB        = arm-cortex_a9-linux-gnueabi-g++

# modifications to linux.conf
QMAKE_AR                = arm-cortex_a9-linux-gnueabi-ar cqs
QMAKE_OBJCOPY           = arm-cortex_a9-linux-gnueabi-objcopy
QMAKE_NM                = arm-cortex_a9-linux-gnueabi-nm -P
QMAKE_STRIP             = arm-cortex_a9-linux-gnueabi-strip

EGLFS_PLATFORM_HOOKS_SOURCES = $$PWD/qeglfshooks_icool4418.cpp
# Preferred eglfs backend
#EGLFS_DEVICE_INTEGRATION = eglfs_viv
load(qt_config)

其中需要注意的有两个地方，一个是include(./opengl.conf)一个是EGLFS_PLATFORM_HOOKS_SORCES中的qeglfshooks_icool4418.cpp

 

这个文件与qmake.conf在同一级目录下，内容如下:

然后在qt源码的同一级目录，新建一个buildarm.sh,内容如下:

 

 

#/bin/sh

	rm -rf $target

#sudo add-apt-repository ppa:ubuntu-toolchain-r/test
#sudo apt-get update

#2 modify qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf

./clean.sh

cd qt-everywhere-opensource-src-5.7.1

if [ -f ./qtbase/mkspecs/linux-arm-gnueabi-g++/opengl.conf ]; then
	rm ./qtbase/mkspecs/linux-arm-gnueabi-g++/opengl.conf
fi

echo "QMAKE_INCDIR_OPENGL_ES2 = $OPENGLINC" >> ./qtbase/mkspecs/linux-arm-gnueabi-g++/opengl.conf

CPU_NUM=$(cat /proc/cpuinfo |grep processor|wc -l)
CPU_NUM=$((CPU_NUM+1))
make -j${CPU_NUM} && make install || exit 1
echo "####build successful!#####"
echo "####install $target#####"
cd $MYDIR
./mktarget.sh

其中buildarm.sh中会新建opengl.conf并向里面填充内容.

 

同时需要tslib和你的opengl相关的头文件和库,目录结构如下图所示:

opengl相关头文件和库可以直接拷贝android源码下的

tslib相关的文件，就是tslib编译安装后生成的所有文件，tslib移植这里就不说明了

clean.sh内容如下:

 

#!/bin/sh
cd qt-everywhere-opensource-src-5.7.1

filelist="qtbase/examples
		  qtbase/qmake
		  qtbase/tests
		  qtconnectivity
		  qtquickcontrols
		  qtscxml
          qtserialbus
		  qtwebview"

if [ -f ./qtbase/Makefile ]; then
	cd ./qtbase
	make distclean
	cd -
	make distclean
	rm -f `find -name *.o` 
	rm -f `find -name *.a` 
	rm -f `find -name *.version.in`
	rm -f `find -name *_wrapper.sh`
	rm -f ./qtbase/bin/qmake
	rm -f ./qtbase/config.status
	rm -rf `find -name .rcc`
	
	for filedir in $filelist; do
		cd $filedir
		#echo "---$PWD"
		rm -f `find -name Makefile`
		cd -
	done

fi

echo "#####clean end ######"

mktarget.sh内容如下:

 

 

#!/bin/sh
SRC_DIR=/opt/qt5.7.1-icool4418

echo "....mktarget start please waiting...."
if [ -f target-qt5.7.1.tar.bz2 ]; then
	rm target-qt5.7.1.tar.bz2
fi

list=`cat << EOF

`
tar -cjvf target-qt5.7.1.tar.bz2 $list

chmod 777 target-qt5.7.1.tar.bz2
echo "....mktarget done...."
echo "+++target:$PWD/target-qt5.7.1.tar.bz2++++"

编译完成最后会在当前目录下生成一个target-qt5.7.1.tar.bz2的文件，直接拷贝根文件系统目录下解压，就可以开始使用了

 

如果需要使用虚拟键盘，还需要修改qtvirtualkeyboard/src/config.pri在

 

# Enable features by languages
contains(CONFIG, lang-ja.*): CONFIG += openwnn

上加上

 

 

#add by hclydao
CONFIG += disable-desktop
CONFIG += lang-zh_CN

然后修改qtvirtualkeyboard/examples/virtualkeyboard/basic/basic.pro如下

#add by hclydao
CONFIG += disable-desktop

disable-desktop|!isEmpty(CROSS_COMPILE)|qnx {
    DEFINES += MAIN_QML=\\\\\\"basic-b2qt.qml\\\\\\"
} else {
    DEFINES += MAIN_QML=\\\\\\"Basic.qml\\\\\\"
}

加上了disable-desktop
