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。
#!/bin/sh ln -s aarch64-linux-gnu-addr2line arm-linux-addr2line ln -s aarch64-linux-gnu-ar arm-linux-ar ln -s aarch64-linux-gnu-as arm-linux-as ln -s aarch64-linux-gnu-c++ arm-linux-c++ ln -s aarch64-linux-gnu-c++filt arm-linux-c++filt ln -s aarch64-linux-gnu-cpp arm-linux-cpp ln -s aarch64-linux-gnu-elfedit arm-linux-elfedit ln -s aarch64-linux-gnu-ct-ng.config arm-linux-ct-ng.config ln -s aarch64-linux-gnu-g++ arm-linux-g++ ln -s aarch64-linux-gnu-gcc arm-linux-gcc ln -s aarch64-linux-gnu-gcc-ar arm-linux-gcc-ar ln -s aarch64-linux-gnu-gcc-nm arm-linux-gcc-nm ln -s aarch64-linux-gnu-gcc-ranlib arm-linux-gcc-ranlib ln -s aarch64-linux-gnu-gcov arm-linux-gcov ln -s aarch64-linux-gnu-gdb arm-linux-gdb ln -s aarch64-linux-gnu-gfortran arm-linux-gfortran ln -s aarch64-linux-gnu-gprof arm-linux-gprof ln -s aarch64-linux-gnu-ld arm-linux-ld ln -s aarch64-linux-gnu-ldd arm-linux-ldd ln -s aarch64-linux-gnu-nm arm-linux-nm ln -s aarch64-linux-gnu-objcopy arm-linux-objcopy ln -s aarch64-linux-gnu-objdump arm-linux-objdump ln -s aarch64-linux-gnu-pkg-config arm-linux-pkg-config ln -s aarch64-linux-gnu-pkg-config-real arm-linux-pkg-config-real ln -s aarch64-linux-gnu-ranlib arm-linux-ranlib ln -s aarch64-linux-gnu-readelf arm-linux-readelf ln -s aarch64-linux-gnu-size arm-linux-size ln -s aarch64-linux-gnu-strings arm-linux-strings ln -s aarch64-linux-gnu-strip arm-linux-strip
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
$vim qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf # # qmake configuration for building with arm-linux-gnueabi-g++ # MAKEFILE_GENERATOR = UNIX CONFIG += incremental QMAKE_INCREMENTAL_STYLE = sublib include(../common/linux.conf) include(../common/gcc-base-unix.conf) include(../common/g++-unix.conf) # modifications to g++.conf #QMAKE_CC = arm-linux-gnueabi-gcc #QMAKE_CXX = arm-linux-gnueabi-g++ #QMAKE_LINK = arm-linux-gnueabi-g++ #QMAKE_LINK_SHLIB = arm-linux-gnueabi-g++ # modifications to linux.conf #QMAKE_AR = arm-linux-gnueabi-ar cqs #QMAKE_OBJCOPY = arm-linux-gnueabi-objcopy #QMAKE_NM = arm-linux-gnueabi-nm -P #QMAKE_STRIP = arm-linux-gnueabi-strip # modifications to g++.conf QMAKE_CC = aarch64-linux-gnu-gcc QMAKE_CXX = aarch64-linux-gnu-g++ QMAKE_LINK = aarch64-linux-gnu-g++ QMAKE_LINK_SHLIB = aarch64-linux-gnu-g++ # modifications to linux.conf QMAKE_AR = aarch64-linux-gnu-ar cqs QMAKE_OBJCOPY = aarch64-linux-gnu-objcopy QMAKE_NM = aarch64-linux-gnu-nm -P QMAKE_STRIP = aarch64-linux-gnu-strip load(qt_config) ~
配置编译参数
#!/bin/sh ./configure -prefix /opt/qt-5.6-arm -release -xplatform linux-arm-gnueabi-g++ -make libs -optimized-qmake -pch -shared -qt-libjpeg -qt-libpng -tslib -I/opt/tslib1.4/include -L/opt/tslib1.4/lib -nomake tools -make examples -iconv
make
make install #在安装example时报错可以不理睬
7. 在/opt/qt-5.6-arm 下生成A64 相关的样例和库
bin doc etc examples include lib mkspecs plugins qml share
8. 新建文件夹,拷贝/opt/qt-5.6-arm/examples ,/opt/qt-5.6-arm/lib, /opt/qt-5.6-arm/plugins ,/opt/tslib1.4/lib, /opt/libiconv/lib/ 并打包放到 开发板上
在开发板上配置环境变量运行测试程序
export QTDIR=/dav/qt-5.6-arm export QT_QPA_FONTDIR=$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 ./svg/embeddedsvgviewer/embeddedsvgviewer
