编译Ts lib

1.下载交叉编译工具链

从官网https://www.veryarm.com/arm-linux-gnueabihf-gcc 下载 或者 https://download.csdn.net/download/pes2020/12833173 下载

解压到并拷贝到/opt/arm-linux-gnueabihf

sudo cp -r ./gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf /opt/arm-linux-gnueabihf

2.配置PATH

gedit /etc/profile

末尾添加

export PATH=/opt/arm-linux-gnueabihf/bin:$PATH

3.下载tslib

官网下载 https://github.com/libts/tslib/releases/download/1.22/tslib-1.22.tar.xz

解压后在代码文件夹编写生成Makefile的脚本 cfg_debug.sh

./configure \
--host=arm-linux  \
--prefix=/opt/arm/debug/  \
CC=/opt/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc \
CFLAGS="-g" 

cfg_release.sh

./configure \
--host=arm-linux  \
--prefix=/opt/arm/release/  \
CC=/opt/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc \
CFLAGS="-O3" 

运行sudo cfg_debug.sh后看有没有报错 生成Makefile

sudo make 编译

sudo make install 将bin和include lib等拷贝到*–prefix=* 指定的位置

编译Qt

1.下载源码

官网 https://download.qt.io/archive/qt/5.9/5.9.7/single/qt-everywhere-opensource-src-5.9.7.tar.xz 下载源码

解压

tar -xvf qt-everywhere-opensource-src-5.9.7.tar.xz 

2.编辑交叉编译平台的qmake配置qmake.conf

选择\qt-everywhere-opensource-src-5.9.7\qtbase\mkspecs\linux-arm-gnueabi-g++\qmake.conf 编辑

#
# qmake configuration for building with arm-linux-gnueabihf-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)

QT_QPA_DEFAULT_PLATFORM=linuxfb
# modifications to g++.conf
QMAKE_CC                = /opt/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc
QMAKE_CXX               = /opt/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++
QMAKE_LINK              = /opt/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++
QMAKE_LINK_SHLIB        = /opt/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++

# modifications to linux.conf
QMAKE_AR                = /opt/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-ar cqs
QMAKE_OBJCOPY           = /opt/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-objcopy
QMAKE_NM                = /opt/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-nm -P
QMAKE_STRIP             = /opt/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-strip
load(qt_config)

3.添加生成Makefile的配置脚本

在代码根目录添加cfg_debug.sh

#!/bin/bash
 ./configure \
 -prefix /opt/arm/debug \
 -xplatform linux-arm-gnueabi-g++ \
 -opensource \
 -debug \
 -confirm-license \
 -no-opengl \
 -no-pch \
 -shared \
 -no-iconv \
 -no-harfbuzz \
 -no-evdev \
 -skip qtdeclarative \
 -nomake examples -nomake tests \
 -no-ssl \
 -tslib \
 -I /opt/arm/debug/include \
 -L /opt/arm/debug/lib
 

4.编译

添加脚本权限 chmod 755 cfg_debug.sh

执行脚本 cfg_debug.sh
