安装交叉编译工具

交叉编译器

下载gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf.tar.xz

sudo mkdir /usr/local/arm
sudo tar xf gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf.tar.xz -C /usr/local/arm/
sudo vi /etc/profile
export PATH=$PATH:/usr/local/arm/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/bin

重启电脑

sudo apt-get install lsb-core lib32stdc++6
arm-linux-gnueabihf-gcc -v

编译 tslib

qt 依赖tslib需要交叉编译

sudo apt-get update
sudo apt-get install autoconf automake libtool

./configure --host=arm-linux-gnueabihf ac_cv_func_malloc_0_nonnull=yes --cache-file=arm-linux.cache -prefix=/home/alientek/tslib-1.21/arm-tslib

make
make install


file bin/ts_calibrate //进入arm-tslib 显示为arm类型

编译其他lib

略

编译 qt

下载qt源码
ubuntu下载地址
wget https://download.qt.io/archive/qt/5.12/5.12.9/single/qt-everywhere-src-5.12.9.tar.xz

修改 qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf

QMAKE_CXXFLAGS += -O2 -march=armv7-a -mtune=cortex-a7 -mfpu=neon -mfloat-abi=hard
include(../common/linux.conf)
include(../common/gcc-base-unix.conf)
include(../common/g++-unix.conf)
# modifications to g++.conf
QMAKE_CC = arm-linux-gnueabihf-gcc
QMAKE_CXX = arm-linux-gnueabihf-g++
QMAKE_LINK = arm-linux-gnueabihf-g++
QMAKE_LINK_SHLIB = arm-linux-gnueabihf-g++
# modifications to linux.conf
QMAKE_AR = arm-linux-gnueabihf-ar cqs
QMAKE_OBJCOPY = arm-linux-gnueabihf-objcopy
QMAKE_NM = arm-linux-gnueabihf-nm -P
QMAKE_STRIP = arm-linux-gnueabihf-strip
load(qt_config)
