全志A64 QT移植

1. 把编译工具 gcc-linaro-aarch64.tar.xz 添加到环境.bashrc 中

2. 下载 tslib-1.4.tar.gz ，libiconv-1.15.tar.gz ，qt-everywhere-opensource-src-5.6.1.tar.gz

3. 由于tslib与libiconv无法识别arch64 所以需要解压编译工具并创建软链接。

　　4. 解压tslib 并编译安装

#!/bin/sh
./autogen.sh
make clean && make distclean
echo "ac_cv_func_malloc_0_nonnull=yes" >arm-linux.cache
CC=arm-none-linux-gcc
./configure --host=arm-linux --prefix=/opt/tslib1.4 --cache-file=arm-linux.cache
make && make install

　　5. 解压libiconv 并编译安装

#!/bin/sh
./configure -prefix=/opt/libiconv -host=arm-linux
make && make install

　　6. 解压qt-everywhere-opensource-src 并编译安装

　修改该gcc配置

$vim 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 = sublib

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

# modifications to g++.conf
#QMAKE_CC                = arm-linux-gnueabi-gcc
#QMAKE_CXX               = arm-linux-gnueabi-g++
#QMAKE_LINK              = arm-linux-gnueabi-g++
#QMAKE_LINK_SHLIB        = arm-linux-gnueabi-g++

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

# modifications to g++.conf
QMAKE_CC                = aarch64-linux-gnu-gcc
QMAKE_CXX               = aarch64-linux-gnu-g++
QMAKE_LINK              = aarch64-linux-gnu-g++
QMAKE_LINK_SHLIB        = aarch64-linux-gnu-g++

# modifications to linux.conf
QMAKE_AR                = aarch64-linux-gnu-ar cqs
QMAKE_OBJCOPY           = aarch64-linux-gnu-objcopy
QMAKE_NM                = aarch64-linux-gnu-nm -P
QMAKE_STRIP             = aarch64-linux-gnu-strip

load(qt_config)
~               

配置编译参数

#!/bin/sh
./configure -prefix /opt/qt-5.6-arm -release -xplatform linux-arm-gnueabi-g++ -make libs -optimized-qmake -pch -shared -qt-libjpeg -qt-libpng -tslib -I/opt/tslib1./include -L/opt/tslib1./lib -nomake tools -make examples -iconv

make

make install #在安装example时报错可以不理睬

7. 在/opt/qt-5.6-arm 下生成A64 相关的样例和库

bin  doc  etc  examples  include  lib  mkspecs  plugins  qml  share

8. 新建文件夹,拷贝/opt/qt-5.6-arm/examples ,/opt/qt-5.6-arm/lib, /opt/qt-5.6-arm/plugins ,/opt/tslib1.4/lib, /opt/libiconv/lib/ 并打包放到 开发板上

在开发板上配置环境变量运行测试程序

export QTDIR=/dav/qt-5.6-arm
export QT_QPA_FONTDIR=$QTDIR/lib/fonts
export QT_QPA_PLATFORM_PLUGIN_PATH=$QTDIR/plugins/
export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
export QT_QPA_PLATFORM=linuxfb:fb=/dev/fb0
export QWS_MOUSE_PROTO=/dev/input/event0
export LD_PRELOAD=/dav/qt-5.6-arm/lib/preloadable_libiconv.so
