Qt-未安装模块“ QtQuick.Controls”

标签: qt qml yocto

我尝试部署在PC上运行良好的QT应用程序。该应用程序部署在基于ASEM的yocto安装映像中,版本为“ morty”。

我收到错误消息“ qml:错误加载组件:qrc:/GUI/InputDialog.qml:3模块“ QtQuick.Controls” 2.0版未安装”

但是,我在LDD输出中看不到任何麻烦:

qml代码中令人反感的行是:

import QtQuick.Controls 2.0

没有成功,我已经在配方中添加了以下代码:

+IMAGE_INSTALL_append = " qtquickcontrols"

目录/ usr / lib / qt5 / qml / QtQuick存在,并且包含libqtquick2plugin.so

在启动应用程序之前将此目录添加到LD_LIBRARY_PATH并不能解决问题。

我已导出: 导出LD_LIBRARY_PATH = / usr / lib / qt5 / qml / QtQuick.2:/ usr / lib / qt5 / qml / QtQuick

我想知道可能缺少什么文件。 可以请人提供如何调试此方法的指示吗?

为了测试Amfasis的想法,我现在还导出

export QML2_IMPORT_PATH =“ / usr / lib / qt5 / qml” 在同一外壳中启动应用程序之前。

ls /usr/lib/qt5/qml/
    Qt  
    QtGraphicalEffects  
    QtLocation  
    QtPositioning  
    QtQml  
    QtQuick  
    QtQuick.2  
    QtTest  
    QtWebChannel  
    QtWebEngine  
    builtins.qmltypes

尽管如此,错误仍然存​​在。

好像我缺少libQt5QuickControls.so 我会深入探讨...

1 个答案:

答案 0 :(得分:0)

供以后参考:

这个想法是在yocto中明确声明一个依赖项。

这可以通过添加

来实现
    RDEPENDS_${PN} = "qtquickcontrols2 \
        qtquickcontrols2-mkspecs \
    "

然后,将编译并安装依赖项。

不过,添加以下内容(我之前已经拥有过)还不够:

DEPENDS = "qtquickcontrols2"
