1 问题

我正在尝试构建开源 motorcar在 Arch Linux 机器上从头开始项目。 Motorcar 是一个 linux VR 窗口管理器,可与 Oculus Rift D2K 耳机和 Razer Hydra Controller 一起使用。你不需要这些项目来实际编译这个项目。

问题:我无法让 motorcar 在我的机器(Arch Linux)上编译。我遇到了 Qt5 链接错误(如下所述)。

2 汽车先决条件和构建目标

作为README表明,为了制造汽车,需要以下先决条件:

  • Mesa,使用 EGL 和桌面 OpenGL 支持编译。
  • Cairo,使用 EGL 和桌面 OpenGL 支持编译。
  • QtWayland 5.5(需要 Qt5.5)。
  • Wayland(一个 linux 窗口管理器协议(protocol))。

  • 此外,汽车项目分为以下实际构建目标:
  • libmotorcar-compositor :这是用于支持此之后的构建目标的实际汽车库。
  • simple-compositor :这是一个简单的 Wayland 合成器,您可以从控制台启动它。一旦启动(在您的屏幕上,而不是在 VR 耳机中),您就可以在其中启动 3D 窗口程序。
  • rift-hydra-compositor : 这与 simple-compositor 相同,但它配备了对 Oculus Rift D2K 耳机和 Razer Hydra Controller 的支持。
  • motorcar-client-demo : 这是客户 "window"意味着在 simple-compositor 中运行或 rift-hydra-compositor .它只是一个旋转的立方体。一旦你启动 simple-compositor ,您应该可以 alt-tab 到控制台并运行 motorcar-client-demo (这将在运行中启动 3D 立方体 simple-compositor )。

  • 3 我如何尝试构建汽车目标(以及我遇到的错误)

    我的系统:带有 nvidia 显卡的 Arch Linux(运行 nvidia 驱动程序)。

    首先请注意,motorcar 项目提供了 build.sh脚本。我试过使用它,但它在我的系统上不起作用。因此,我从源代码编译了所有内容。这是我的做法(导致最终错误)。

    3.1 我是如何构建 Mesa 的

    首先我下载了​​ mesa-13.0.2.tar.gz来自 mesa .将其从 tar 中删除后,我运行:
    $ ./configure --prefix=$WLD --enable-gles2 --disable-gallium-egl --with-egl-platforms=x11,wayland,drm --enable-gbm --enable-shared-glapi --with-gallium-drivers=r300,r600,swrast,nouveau --enable-glx-tls # what should $WLD be here? It might have been left blank.
    $ make
    $ sudo make install

    3.2 我是如何 build 开罗的

    首先我下载了​​ LATEST-cairo-1.14.6链接自 cairo's website .将其从 tar 中删除后,我运行:
    $ ./configure --prefix=$WLD --enable-xcb=yes --enable-gl=yes -enable-egl=yes # what should $WLD be here? It might have been left blank.
    $ make
    $ sudo make install

    3.3 我是如何构建 Wayland 的

    我只是为此使用了我的包管理器。
    $ sudo pacman -S wayland
    $ sudo pacman -S weston # in case this is relevant

    3.4 我如何构建 qtwayland 和 qt5.5

    在这里,我按照汽车自述文件的说明进行操作:
    $ cd ~
    $ git clone git://code.qt.io/qt/qt5.git qt5
    $ cd qt5
    $ git checkout 1497a398e34e18abb18f705b2294464840629ca1 # the Qt5 commit hash confirmed to work from the README
    $ ./init-repository --no-webkit --module-subset=qtbase,qtdeclarative,qtwayland # I removed qtjsbackend from the module-subset since it isn't strictly needed

    $ cd qtbase
    $ git checkout 7010da2e6274febf71db40a535ce1d0c4858f143 # the qtbase commit hash confirmed to work from the README
    $ cd ../qtwayland
    $ git checkout 3dc9cfdbd2771c28c770d432b99e571db43fe599 # the qtwayland commit hash confirmed to work from the README
    $ cd ../
    $ ./configure -prefix /opt/qt5 -debug -confirm-license -opensource -egl -opengl -no-xcb-xlib

    $ cd qtwayland
    $ git clean -fdx
    $ ../qtbase/bin/qmake CONFIG+=wayland-compositor
    $ cd ../
    $ make -j4 # the -j4 flag speeds up make by a factor of 4; otherwise this build takes a LONG time
    $ make install

    3.5 我是如何构建的 libmotorcar-compositor
    $ cd ~
    $ git clone https://github.com/evil0sheep/motorcar.git motorcar
    $ /opt/qt5/bin/qmake
    $ make

    3.6 我是如何尝试构建但失败的 simple-compositor

    最佳答案

    尝试添加Qt的bin目录到 PATHlib目录到 LD_LIBRARY_PATH :

    export PATH=/opt/qt5/bin:$PATH
    export LD_LIBRARY_PATH=/opt/qt5/lib:$LD_LIBRARY_PATH

    我相信你可能已经链接了你的 shared-object.so库明确反对 /opt/qt5/lib/libQt5Core.so ,但由于它又依赖于其他 Qt 库并且无法找到它们,因此您遇到了错误。上述调整可能会解决问题。

    也可以看看:
  • What is the difference between PATH and LD_LIBRARY_PATH?
  • Where is LD_LIBRARY_PATH? how do I set the LD_LIBRARY_PATH env variable?
  • man ld.so(8)
