下载交叉编译链接工具

安装交叉编译器

解压

sudo tar -xvf gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu.tar -C /opt/
sudo tar -xvf gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf.tar -C /opt/

解压完成后，配置环境变量

sudo vim ~/.bashrc

添加编译器路径：路径为你解压后路径，我的路径为：/opt/

PATH=$PATH:/opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin
PATH=$PATH:/opt/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin

配置生效

source ~/.bashrc

验证是否安装成功

aarch64-linux-gnu-gcc -v
arm-linux-gnueabihf-gcc -v

arm32如下为成功。

aarch64如下为成功

测试交叉编译器

写一个简单的c程序，交叉编译后放到开发板上去运行看看 能否运行成功

#include <stdio.h>
int main(int argc, char **argv)
{
    printf("Hello, you do it succeed!!!\n");
    return 0;
}

• 先使用arm32编译

编译完成后，看到文件是32位的。

移植到arm32板子上，可以运行成功。

• aarch64编译

编译完成后，看到文件是arm 64位的。

移植到aarch64的板子上，可以运行成功。

由此可见，两种交叉编译工具都安装成功，可以使用。

编译Qt源码

这里只是用aarch64编译器去编译qt源码

下载Qt源码

解压qt源码

sudo tar xvf qt-everywhere-src-5.12.10.tar.xz
cd  qt-everywhere-src-5.12.10

修改qmake配置文件

首先复制一份文件

sudo cp -a linux-aarch64-gnu-g++/ aarch64-linux-gnu-g++/

修改配置文件目录，后面都改成你交叉编译器安装的路径。”/opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/“

配置编译参数

Linux 下 qt5的安装及库编译（1）_hrx-@@-CSDN博客

qt5的configure选项说明（2）_hrx-@@-CSDN博客

1. 建议是新建一个build目录，然后在该目录下配置configure，make之类的，这样子配置编译生成的临时文件会放在该目录下，而不会污染源码。

2. 在build目录下创建一个build.sh的脚本，添加如下内容

../qt-everywhere-src-5.12.10/configure \
-verbose \
-opensource \
-release \
-shared \
-confirm-license \
-make libs \
-nomake tests \
-nomake examples \
-skip qtmacextras \
-skip qtandroidextras \
-no-opengl \
-xplatform aarch64-linux-gnu-g++ \
-prefix /opt/qt-5.12.10-linux-aarch64-gcc

verbose：打印配置过程中步骤信息
opensource：编译Qt的开源版本
release：编译Qt的release版本
shared：构建 Qt 共享库
confirm-license：自动确认许可
make libs：编译 lib 组件
nomake tests：不编译 tests组件
nomake examples：不编译 examples 组件
skip qtmacextras：跳过 qtmacextras 模块
skip qtandroidextras：跳过 qtandroidextras 模块

no-opengl: 我在虚拟机下编译opengl模块报错，未解决 所以选择不编译

xplatform： 选择交叉编译时的目标 mkspec

prefix ：指定 make install 的位置

./configure -release -opensource -confirm-license -xplatform aarch64-linux-gnu-gcc  -prefix /opt/aarch64—qt5 -nomake examples -nomake tools -nomake tests -no-opengl

Note: Disabling X11 Accessibility Bridge: D-Bus or AT-SPI is missing.

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/opt/qt-5.12.10-linux-aarch64'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

执行make

对源码进行编译，时间挺长的，大约三四个小时。

make -j8

执行make install

sudo make install

在编译完成后执行 make install 会将qt库安装到 -prefix 指定的目录下。

查看库的系统架构

可以库安装路径下面，readelf - h xxx.so 可以看到编译出来的库系统架构是Aarch64的。

配置qtcreator交叉编译环境

在ubuntu下搭建Qt Creator的arm交叉编译环境_bigmarshal的博客-CSDN博客

首先没有安装qtcreator，需要安装

sudo apt-get install qtcreator

添加交叉编译工具链

编译器路径，选择你之前安装的路径，我的路径为：

c++

/opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-g++

c

/opt/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc

选择qmake版本，路径为你编译输出的路径。

添加Kit

创建个带界面的工程进行交叉编译测试

选择Aarch64编译

程序依赖库也是正常的。

可以看出编译生成的应用程序是ARM aarch64的。接下来打包后移植到rk3399中执行打开。

最后可以看出大功告成~~~

疑问？

1. 假如用rk3399上所有qt的依赖库，再加上qmake和gcc编译工具，不知道是否可以跳过编译qt源码这个步骤，直接使用现有的依赖库？
2. 能够直接可以使用别人交叉编译后的依赖库已经qmake等编译工具？
