编译qcreator源码
背景
在 ARM 架构下，UOS 系统，需要使用 Qt 5.15.2 版本环境，所以只能通过源码编译的形式进行 Qt 环境的部署。
软硬件相关信息：
- 处理器: 飞腾 FT-2000 4 核
- 制造商: Phytium
- 架构: aarch 64
- 家族: ARMv 8
- 系统：UOS V 20 1060
- 内核：4.19.0-arm 64-desktop
下载 Qt、Qtcreator 源码
这里选择的是国内的镜像地址进行下载源码。
Qt 5.15.2： http://mirrors.ustc.edu.cn/qtproject/archive/qt/5.15/5.15.2/single/
Qt Creator： http://mirrors.ustc.edu.cn/qtproject/archive/qtcreator/
需要注意的是，QtCreator 的版本要和 Qt 大版本对应。比如，Qtcreator 11 版本采用 Qt 6 编译，如果你下载的 Qt 源码是 Qt 5 版本的，那么编译时，会找不到 Qt 6 相关的 cmake 文件，无法进行编译。是否适合当前版本，可以通过 qt-creator-opensource-src 里的 README.md 中介绍确定对应的版本。
下载完成后，使用 tar 命令进行解压
tar -zxvf qt-everywhere-src-5.15.2.tar.xz
tar -zxvf qt-creator-opensource-src-7.0.2.tar.gz
- 1

环境配置
安装 Qt 所需的依赖：
sudo apt install build-essential libgl1-mesa-dev libxkbcommon-dev libnss3-dev libdbus-1-dev gperf flex bison
- 1
安装 xcb 相关：
sudo apt-get install '^libxcb.*-dev' libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev libxkbcommon-dev libxkbcommon-x11-dev
- 1
这一步比较关键，因为涉及到编译之后有 libqxcb.so，如果缺失会导致错误。
如果需要使用到 QWebEngine 模块，那么需要安装以下依赖库：
sudo apt install libxcursor-dev libxcomposite-dev libxdamage-dev libxrandr-dev libxtst-dev libxss-dev libdbus-1-dev libevent-dev libfontconfig1-dev libcap-dev libpulse-dev libudev-dev libpci-dev libnss3-dev libasound2-dev libegl1-mesa-dev gperf bison nodejs
- 1
编译 Qt
进入解压后的 qt-everywhere-src-5.15.2 目录，开始配置：
./configure -prefix /home/leo/Qt -opensource -confirm-license -nomake examples -release
- 1
-prefix /home/leo/Qt: 指定 Qt 的安装路径-opensource: 指定使用开源版本-nomake examples: 不编译 examples-release: release 模式
这个步骤会检查相关的库是否存在，若不存在则将缺少的安装。
安装完缺失的依赖库后，记得先删除 config.cache 缓存文件。
或者使用脚本运行，创建 run.sh 脚本：
#! /bin/bash
./configure -prefix /home/leo/Qt/5 \
-opensource -confirm-license \
-nomake examples \
-nomake tests \
-release \
-skip qt3d \
-skip qtcharts \
-skip qtandroidextras \
-skip qtlocation \
-skip qtmultimedia \
-skip qtsensors \
-skip qtserialbus \
-skip qtserialport \
-skip qtwayland

可以指定跳过编译哪些模块以加快编译速度
开始编译：
make

此过程示机器性能不同，时长不同。
在编译过程中，可能会遇到一些依赖问题，需要根据实际情况进行解决。
当编译完成后，即可安装了
make install

编译 Qt Creator
编译 Qt Creator 则可使用 cmake 工具进行编译：
cd qt-creator-opensource-src
cmake -B build -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH=/home/leo/Qt -DCMAKE_INSTALL_PREFIX=/home/leo/Qt/Tool/QtCreator
cmake --build build --target=install

解决方法：
这个错误是由于 QWebengine 模块的 chromium 包含的 third_party 里第三方库 libjpeg_turbo 在 ARM 下的兼容问题，可以逐个对比 GitHub 的代码修改错误，也可以尝试将最新的 libjpeg_turbo 源文件覆盖。
leo@leo-PC:/data/home/leo/Qt/Tool/QtCreator/bin$ ./qtcreator
qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in "/home/leo/Qt/5.15.2/plugins/platforms"

查看 /home/leo/Qt/5.15.2/plugins/platforms 安装目录下是否有 libqxcb.so 库，如果没有，则说明源码编译不完整。
需要安装 xcb 相关的库
sudo apt-get install '^libxcb.*-dev' libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev libxkbcommon-dev libxkbcommon-x11-dev
- 1
然后重新编译尝试。
总结
以上便是在 ARM 架构平台的 Linux 系统上编译 Qt 整个过程，在编译过程中，需要特别注意的便是依赖库的完整性，如果缺失一些依赖库，Qt 并不会直接报错，编译之后才发现缺失依赖库，有的组件用不了。尤其是 libqxcb.so 库，最开始编译的时候，没用生成它，导致程序无法启动。
所以要特别留意 ./configure 那一步，Qt 会检测相关的环境及依赖库。
