Install trace-cmd

还算顺利，大部分依赖包从系统 apt 源里都能安装，但也有一些问题

  • /usr/lib64/pkgconfig 没有在 pkg-config 默认的 search paths 里
    • export PKG_CONFIG_PTH=/usr/lib64/pkgconfig 可解决构建问题
  • /usr/lib64 没有在 ld.so 的默认的 search paths 里
    • /etc/ld.so.conf.d/x86_64-linux-gnu.conf 里增加 /usr/lib64 可解决运行时找不到 shared library 的问题
  • 因为 xmlto 的依赖问题无法安装，幸好它只是用来构建 Documentation, 通过 -Ddoc=false 不构建就可以继续下去

Install apitrace

apitrace 不带 GUI 的话可以非常顺利的安装，带 GUI 的话因为依赖 Qt5/6, 稍微麻烦一点

    endif()
    if (ENABLE_QT6)
        find_package (Qt6 COMPONENTS Widgets Network ${REQUIRE_GUI})
    else ()
        find_package (Qt5 5.15 COMPONENTS Widgets Network ${REQUIRE_GUI})
    endif ()
endif ()

Install Qt

一开始通过 qt-online-installer-linux-x64-4.8.1.run 安装 Qt 6.8, 安装后 cmake find_package 还是有问题，就只能源码安装 qt 5.15.16

  • mkdir -p /opt/Qt5.15
  • mkdir -p ~/qt-build
  • cd ~/qt-build
  • ~/qt-everywhere-src-5.15.16/configure -prefix /opt/Qt5.15
  • make -j $(nproc)
  • sudo make install

Qt 5.15.16 安装完成后就可以继续安装 qapitrace 了

  • cd ~/apitrace
  • cmake -B build -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_MODULE_PATH=/opt/Qt5.15/lib/pkgconfig
  • sudo cmake --install build

可惜安装后运行 qapitrace glxgears.trace 报段错误，难道是 Qt 的版本太高了?

m_cfgPath... "/usr/share/qt5-ukui-platformtheme/themeconfig/default.json"
段错误

将 /opt/Qt5.15/lib 添加到 ld.so.conf 后又报出下面的错误, 提示 Qt 缺少 wayland, xcb platform plugin

qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in ""
qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, webgl.

已放弃

所以检查编译配置，发现 QPA backends 中的 EGLFS 虽然打开了，但 EGLFS details 里所有的后端一个也没有打开， 阅读 EGLFS 的文档 后了解到 EGLFS 似乎是运行在 EGL 和 OpenGL ES 2.0 之上， 但 Qt Gui 里的 OpenGL ES 2.0/3.0/3.1/3.2 都没有开启， 还有 XCB Xlib 也没有开启。

所以继续阅读 Qt for X11 requirements 文档, 安装文档中所有列出的依赖软件包后， 重新编译 Qt 5.15.16, 这次 qapitrace 运行正常，而且之前报出的缺少 Qt Platform plugin “xcb” in “” 也消失了

PAL

Qt Platform Abstraction (QPA) 是 Qt 中主要的平台抽象层 (Platform Abstraction Layer), PAL 这个概念在 AMD GPU 驱动中也有， 在 Android 里也有类似的 HAL (Hardware Abstraction Layer) 的概念，在系统软件设计中， PAL 的作用可谓是"承上启下"， 设计一个接口稳定，易于扩展的 PAL API 是整个用户态系统软件实现效率的关键。通过这次安装 Qt, 又多了一个学习的例子。
