问题描述
为了测试 QML 部署,我创建了一个非常简单的 QML 应用程序.代码如下:
To test QML deployment I've created a very simple QML application. Here is the code:
main.cpp
#include <QApplication>
#include <QQmlApplicationEngine>
#include <QFile>
int main(int argc, char **argv) {
QApplication app(argc, argv);
QQmlApplicationEngine engine;
QString path = app.applicationDirPath() + "/qml/main.qml";
if(QFile::exists(path))
engine.load(path);
else {
return 1;
}
return app.exec();
}
main.qml
import QtQuick 2.2
import QtQuick.Controls 1.2
ApplicationWindow {
id: mainWindow
title: "Test window"
width: 800
height: 600
visible: true
}
为了确保系统中没有安装开发库,我设置了一个安装了纯 Windows XP 的虚拟机.然后,我按照此处所述的说明操作并复制了all Qt5*.dll 进入程序目录,以及platforms/qwindows.dll 和icu*52.dll.Dependency Walker 确认没有留下损坏的依赖项,即一切都应该正确设置.
To be sure no development library was installed in the system, I've set up a virtual machine with a pure Windows XP installation. Then, I've followed instructions as described here and copied all Qt5*.dll into the program directory, as well as platforms/qwindows.dll and icu*52.dll. Dependency Walker confirmed that no broken dependencies were left, i.e. everything should have been correctly set up.
但是,由于某些原因,当我运行我的应用程序时,我什么也看不到.既不是窗口,也不是错误消息.从控制台运行也没有给我任何错误.尽管如此,我可以看到我的应用程序在任务管理器中运行,就像它在后台运行一样.在开发机器上运行应用程序没有问题:应用程序正确启动,我可以看到它的窗口.
However, for some reasons, when I run my app I see nothing. Neither a window, nor an error message. Running from console also gives me no error. Despite this, I can see my app running in the Task manager, like it is running in background. Running the app on the development machine goes without problem: the app correctly starts and I can see its windows.
我做错了什么?我如何部署 QML 应用以确保它可以在任何其他非开发机器上运行?
What am I doing wrong? How can I deploy a QML app to be sure it will work on any other - non development - machine?
推荐答案
如果您使用 MinGW,则尝试将文件夹 qml 和 plugins 中的所有文件夹复制到目录中你的程序.同时复制库:icudt52.dll
、icuin52.dll
、icuuc52.dll
、libgcc_s_dw2-1.dll
、libstdc++-6.dll
、libwinpthread-1.dll
、Qt5Core.dll
、Qt5Gui.dll
、Qt5Network.dll
、Qt5Qml.dll
、Qt5Quick.dll
、Qt5Svg.dll
、Qt5Widgets.dll
代码>来自bin
If you use MinGW, then try to copy all folders from folders qml and plugins to directory with your program. Also copy libraries: icudt52.dll
, icuin52.dll
, icuuc52.dll
, libgcc_s_dw2-1.dll
, libstdc++-6.dll
, libwinpthread-1.dll
, Qt5Core.dll
, Qt5Gui.dll
, Qt5Network.dll
, Qt5Qml.dll
, Qt5Quick.dll
, Qt5Svg.dll
, Qt5Widgets.dll
from bin
最终目录将如下所示:
- 引擎
- 图像格式
- 平台
- Qt
- QtGraphicalEffects
- Qt定位
- QtQml
- QtQuick
- QtQuick.2
- Qt传感器
- QtWebKit
- QtWinExtras
- icudt52.dll
- icuin52.dll
- icuuc52.dll
- libgcc_s_dw2-1.dll
- libstdc++-6.dll
- libwinpthread-1.dll
- Qt5Core.dll
- Qt5Gui.dll
- Qt5Network.dll
- Qt5Qml.dll
- Qt5Quick.dll
- Qt5Svg.dll
- Qt5Widgets.dll
- YOUR_PROGRAM.exe
这种方式适用于未安装 Qt 的 WindowsXP/Win7.
This way works on WindowsXP/Win7 where Qt was not installed.
