Qt5.12.8的QtWebEngine库编译随笔（rk3588板卡）

起因编译环境源码配置编译遇到问题

引用

起因

项目从rk3399板卡改为rk3588后原先的qtwebengine库直接无法使用了，故尝试在新的板卡下进行编译。

编译环境

板卡: rk3588

系统: unbuntu 20.04 LTS

gcc version: aarch64-linux-gnu 9.4.0

源码

下载地址：https://download.qt.io/new_archive/qt/5.12/5.12.8/single/

下载到板块后解压

<code>sudo tar -xf qt-everywhere-src-5.12.8.tar.xz

cd qt-everywhere-src-5.12.8

配置

由于配置的信息相当多，建议创建一个自动配置脚本，比如auto.sh，方便根据自己的系统进行参数调整。

sudo touch auto.sh

sudo chmod 755 auto.sh

sudo vim auto.sh

#auto.sh

./configure -prefix /root/honglingfeng/arm-qt-5.12.8 \

具体configure参数解析可以参考以下文章：https://blog.csdn.net/qing666888/article/details/79597473

官方英文帮助文档: ./configure --help

注意：每次改变auto.sh里面的参数，记得将config.cache删除后在运行脚本

运行auto.sh脚本进行配置

因为缺少依赖文件，绝大部分情况下configure都无法通过的，即报WARNING: QtXXX will not be built.。所以必须要安装依赖文件，直到不报错为止。

Qt is now configured for building. Just run 'make'.

Once everything is built, you must run 'make install'.

Qt will be installed into '/root/honglingfeng/arm-qt-5.12.8'.

Prior to reconfiguration, make sure you remove any leftovers from

the previous build.

QWebEngine基础依赖

sudo apt-get install bison flex gperf libdus* dbus* libfontconfig1-dev fontconfig libnss3-dev python2 pkg-config

sudo apt-get install libicu-dev ninja-build

OpenGL相关依赖

sudo apt-get install libgl1-mesa-dev libglu1-mesa-dev libegl1-mesa-dev freeglut* libgles* libglew*

xcb相关依赖

sudo apt-get install libxkbcommon-x11-dev

sudo apt-get install libxcb-xinerama0-dev

sudo apt-get install libxcb-sync-dev

若报Could not find all necessary libraries for qpa-xcb support

建议再安装一遍依赖

sudo apt-get install bison build-essential gperf flex libasound2-dev\

libcups2-dev libdrm-dev libegl1-mesa-dev libnss3-dev libpci-dev\

libpulse-dev libudev-dev nodejs libxtst-dev gyp ninja-build\

libssl-dev libxcursor-dev libxcomposite-dev libxrandr-dev

QtWebEngine库大部分问题都是没有依赖库导致的，如果出错就安装相关的依赖库即可。

编译

make -j4

make install

这里要提一下QWebEngine使用了chromium-browser大部分功能，基本第三方库中的chromium都需要编译。rk3588板卡只有8g内存，需要添加10G swap虚拟内存空间来支持编译。不然容易编译中途因为内存耗尽而中断。

sudo mkdir /swapfile

sudo dd if=/dev/zero of=swapfile bs=1G count=10

sudo mkswap /swapfile

# 开启

sudo swapon /swapfile

# 查看是否启用

free -h #swap那一栏

遇到问题

build chromium错误

WARNING: C++14 support is required in order to build chromium.

WARNING: QtWebEngine will not be built.

可以通过安装chromium-brower解决

sudo apt update

sudo apt install chromium-browser
