前言

最近工作中要求客户端和服务端通过ssl加密通信,其中客户端是qt编程,服务端是linux编程.我的开发环境是ubuntu16.04;运行环境是debian9.13,是基于gnu的linux操作系统,64位arm架构.

一、编译安装openssl

首先要确定qt版本对应的openssl版本,我使用的是qt5.7.1+openssl1.0.2,如果qt和openssl版本不对应,后面编译qt会编译失败.
下载openssl-1.0.2.tar.gz,下载地址:

然后依次执行如下命令:

tar -zxvf openssl-1.0.2.tar.gz
cd openssl-1.0.2

./config no-asm shared --prefix=/opt/W6460-openssl-qt-lib/openssl-1.0.2-build/ --cross-compile-prefix=/opt/tools/gcc-linaro-6.3.1-2017.05-i686_aarch64-linux-gnu/bin/aarch64-linux-gnu-

sed -i 's/-m64/ /g' Makefile

make -j4

sudo make install

编译完成后,如下:

二、编译qt5.7.1

下载qt-everywhere-opensource-src-5.7.1-source.tar.gz,下载地址:
链接: https://pan.baidu.com/s/10o5WwzJF2HVPLvbUV8dSCg 提取码: inmi
执行如下命令:

tar -zxvf qt-everywhere-opensource-src-5.7.1-source.tar.gz
cd qt-everywhere-opensource-src-5.7.1-source/qtbase/mkspecs

查看是否存在aarch64-linux-gnu-g++文件夹,如不存在，则复制arm-linux-gnueabihf-g++到aarch64-linux-gnu-g++
然后执行如下命令:

cd aarch64-linux-gnu-g++
vi qmake.config

修改内容如下:

#
# qmake configuration for building with arm-linux-gnueabihf-g++
#

MAKEFILE_GENERATOR      = UNIX
CONFIG                 += incremental
QMAKE_INCREMENTAL_STYLE = sublib

QT_QPA_DEFAULT_PLATFORM = linuxfb

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

# 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)

在qt源码父目录,新建一个build.sh文件,内容如下:

#!/bin/sh

export W6460_QT_INSTALL=/opt/W6460-openssl-qt-lib
export PKG_CONFIG_LIBDIR=/opt/tools/gcc-linaro-6.3.1-2017.05-i686_aarch64-linux-gnu/aarch64-linux-gnu/lib64
export CROSS_COMPILE=aarch64-linux-gnu-

Cur_Dir=$(pwd)
QT_SORCE=qt-everywhere-opensource-src-5.7.1-source
echo $Cur_Dir
export W6460_QT_BUILD=$Cur_Dir
export PATH=$W6460_QT_INSTALL/bin:$PATH
cd $QT_SORCE
