QtCreator启动时 dbus-1的错误解决方法



  • Qt 5.12.0,QtCreator4.8.0启动时提示dbus-1的错误解决方法

    ...version LIBDBUS_1_3 not defined in file libdbus-1.so.3...
    

    需要更新dbus

    1.打开https://dbus.freedesktop.org/releases/dbus/
    2.下载dbus-1.13.6.tar.gz
    3.linux终端

    $tar -zxvf dbus-1.13.6.tar.gz
    

    4.进入dbus-1.13.6文件夹

    $./configure
    

    5.失败,说明D-Bus daemon需要expat XML parser 库,所以这里需要先编译expat库

    $sudo apt-get install libexpat1-dev
    

    6.重新进行4步骤
    7.编译安装dbus

    $make
    $make install
    

    8.安装完成,更新连接文件

    $cp /usr/local/lib/libdbus-1.so.3.24.0 /lib/x86_64-linux-gnu
    

    如果没有x86_64-linux-gnu这个目录,可以拷贝到/lib

    $ln -sf /lib/x86_64-linux-gnu/libdbus-1.so.3.24.0 /lib/x86_64-linux-gnu/libdbus-1.so.3
    

    9.再次启动QtCreator4.8.0,提示

    dbus[17254]: D-Bus library appears to be incorrectly set up: see the manual page for dbus-uuidgen to correct this issue. (Failed to open "/usr/local/var/lib/dbus/machine-id": No such file or directory; Failed to open "/etc/machine-id": No such file or directory)
      D-Bus not built with -rdynamic so unable to print a backtrace
    Aborted (core dumped)
    

    缺少machine-id文件,需要给它定义一个id,使用dbus-uuidgen创建id文件

    $sudo dbus-uuidgen > /etc/machine-id
    

    10.再次启动QtCreator4.8.0成功

  • @bladesero Blender 在角色建模和渲染这些方面的确比较强。😄

    我们的软件还在发展中呢。

  • 背景:如果需要qml显示循环list,一般是用3个ListView循环交替,实现伪循环,期间逻辑复杂,容易出错,PathView本身自带循环,所以考虑用PathView实现循环

    设计:PathView显示5条数据,按照垂直List一个个排好顺序,由于收尾移动时候会空白穿帮,所以用clip控制显示中间三条数据

    滚动控制:currentIndex,decrementCurrentIndex(),incrementCurrentIndex()

    代码:

    Item{ id: item1 property int myIndex: 0 property int onePageCount: 3 property real oneHeight: 72 property real oneWidth: 580 property int isCurrentListView: 1 //0,1,2 property bool isAdd: true //direction,down=true,up=false property int hightlightIndex: 0 property int currentIndexPathView: 0 //use this Item{ id: itemClip width: item1.oneWidth height: item1.oneHeight*3 clip: true PathView { id: listView1 width: item1.oneWidth model: listModelSpeedWarning delegate: delegeteLine pathItemCount: item1.onePageCount+2 interactive: false path: Path { startX: item1.oneWidth/2 startY: -item1.oneHeight/2 PathQuad { x: item1.oneWidth/2; y: item1.oneHeight*0+item1.oneHeight/2; controlX: item1.oneWidth/2; controlY: item1.oneHeight*0+item1.oneHeight/2 } PathQuad { x: item1.oneWidth/2; y: item1.oneHeight*1+item1.oneHeight/2; controlX: item1.oneWidth/2; controlY: item1.oneHeight*1+item1.oneHeight/2 } PathQuad { x: item1.oneWidth/2; y: item1.oneHeight*2+item1.oneHeight/2; controlX: item1.oneWidth/2; controlY: item1.oneHeight*2+item1.oneHeight/2 } PathQuad { x: item1.oneWidth/2; y: item1.oneHeight*3+item1.oneHeight/2; controlX: item1.oneWidth/2; controlY: item1.oneHeight*3+item1.oneHeight/2 } PathQuad { x: item1.oneWidth/2; y: item1.oneHeight*4+item1.oneHeight/2; controlX: item1.oneWidth/2; controlY: item1.oneHeight*4+item1.oneHeight/2 } } Component.onCompleted: { listView1.currentIndex = -1 } } } }

    问题:windows下测试,按住按键不松手,list滚动会卡住,松手后恢复正常,看来list不能滚动太快
