银河麒麟(Kylin) - V10 SP1桌面操作系统ARM64编译QT-5.15.12版本

在这里插入图片描述

原因

测试Kylin-Desktop-V10-SP1-General-Release-2303-arm64系统下，编译QT-5.15.12版本已做测试。

测试环境

测试板配置

型号：LM-D2000-NONE-1w-V01-pc_A2150
CPU：飞腾D2000/8 （2.3GHz）
内存：32G
硬盘：256G SSD
系统：Desktop-V10-SP1-General-Release-2303
平台架构：ARM

准备工作

去QT官网下载QT-5.15.12源码
确保系统的gcc，g++， python， perl等符合Qt安装要求,具体请参见Qt源码内的README文档

编译

编译安装QT

进入qt-everywhere-src-5.15.12目录执行以下命令：

sudo ./configure -prefix /opt/qt5.15.12 -xcb -nomake tests -nomake examples

在这里插入图片描述

make -j8  #-j8为编译时多核优化，视物理机而定

在这里插入图片描述

make install  #然后执行安装

编译中途报错缺少库依赖，自行安装缺少的库。

sudo apt-get install '^libxcb.*-dev' libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev libxkbcommon-dev libxkbcommon-x11-dev

sudo apt-get install gperf  bison flex host pkg-config

问题

我在编译过程中报错error： [Makefile.gn_run:1169：run_ninja] 错误 1

ninja: build stopped: subcommand failed.
make[4]: *** [Makefile.gn_run:1169：run_ninja] 错误 1

QtWebEngine编译失败的问题，错误信息还是关于ninja停止构建

安装缺失依赖库：

sudo apt install \libnss3-dev libdrm-dev libxcomposite-dev libxcursor-dev \libxi-dev libxtst-dev libxkbfile-dev libxkbcommon-dev \libfontconfig1-dev libdbus-1-dev libevent-dev libwebp-dev \libicu-dev libxslt1-dev libxml2-dev libjpeg-dev libpng-dev \libssl-dev libopus-dev libminizip-dev libsnappy-dev \libjsoncpp-dev libre2-dev protobuf-compiler ninja-build

修复 Python 环境

确保默认 python 指向 Python 3.6+：

sudo ln -sf /usr/bin/python3 /usr/bin/python

清理并重新配置 Qt

cd /home/zhang/qt-everywhere-src-5.15.12
make distclean
rm -rf config.cache
# 重新配置
./configure -prefix /opt/qt5.15.12 -xcb -nomake tests -nomake examples

如果仍失败

检查 config.log

+ /usr/bin/pkg-config --exists --silence-errors poppler-cpp
pkg-config did not find package.=> source produced no result.
test config.qtwebengine_core.libraries.webengine-poppler-cpp FAILED
loaded result for library config.qtwebengine_core.libraries.webengine-pulseaudio

+ /usr/bin/pkg-config --exists --silence-errors libpulse '>=' 0.9.10 libpulse-mainloop-glib
pkg-config did not find package.=> source produced no result.
test config.qtwebengine_core.libraries.webengine-pulseaudio FAILED

错误分析：

QtWebEngine 在配置阶段检测到两个关键依赖库缺失：

poppler-cpp（PDF 渲染支持）
libpulse（音频支持）

虽然这些库不是 QtWebEngine 的核心依赖（构建仍可继续），但缺失会导致部分功能受限（如 PDF 预览、音频播放）。以下是解决方案：

安装缺少的库

sudo apt update
sudo apt install \libpoppler-cpp-dev \      # poppler-cpplibpulse-dev \            # libpulselibglib2.0-dev           # libpulse 的依赖

安装缺少的库

sudo apt-get install bison build-essential gperf flex ruby python libasound2-dev libbz2-dev libcap-dev libcups2-dev libdrm-dev libegl1-mesa-dev libgcrypt* libnss3-dev libpci-dev libpulse-dev libudev-dev libxtst-dev gyp ninja-build  libglu1-mesa-dev libfontconfig1-dev libx11-xcb-dev libicu-dev pulseaudio* libxkbcommon* libxcb* libthread* libgstreamer*

编译 Qt 文档 (QDoc)警告：（可以忽略）

警告：WARNING: QDoc will not be compiled, probably because libclang could not be located. This means that you cannot build the Qt documentation.Either ensure that llvm-config is in your PATH environment variable, or set LLVM_INSTALL_DIR to the location of your llvm installation.
On Linux systems, you may be able to install libclang by installing the libclang-dev or libclang-devel package, depending on your distribution.
On macOS, you can use Homebrew's llvm package.
On Windows, you must set LLVM_INSTALL_DIR to the installation path.

这个警告表明你的系统缺少编译 Qt 文档 (QDoc) 所需的依赖项 - libclang。QDoc 是 Qt 的文档生成工具，它依赖于 LLVM/Clang 来解析 C++ 代码。
