在Windows上部署Qt 5应用程序 [英] Deploying Qt 5 App on Windows

问题描述

我在QML中写了几个应用程序（Qt 5的一部分）。在我之前提到的一个问题（ https：// softwareengineering.stackexchange.com/questions/213698/deploying-qt-based-app-on-mac-os-x ），我找到了在OS X上部署我的应用程序的解决方案（使用macdeployqt工具）。

在Windows上部署Qt4应用程序很简单：

2. 您复制了必需的库（DLL）。


3. 您已经测试过，它的工作。

不幸的是，这种方法在Qt5中不起作用（我甚至包括了qwindows.dll文件的platform文件夹，它没有起作用）。经过几天的尝试，我放弃了编辑了一个静态版本的Qt5。

再次，它没有工作。该应用程序在安装了Qt的PC上工作，但它在干净的PC上崩溃。作为附注，Windows 8 / 8.1系统不会发出警告或通知我有关应用程序崩溃的消息。但是在Windows 7中，一条消息通知我应用程序崩溃。

我已经尝试运行Dependency Walker（depends.exe）和静态构建我的应用程序中的所有库似乎很好。

在Windows 8中，我没有收到任何错误。但是在将该应用程序分析到depends.exe之后，我会收到源自QtGui.dll的访问冲突。确切的错误是

第二次机会异常0xC0000005（访问冲突）发生在地址为0x61C2C000的QT5GUI.DLL中。

有没有什么我想要的（说一个额外的DLL或配置文件）？

应用程序信息：

• 使用Qt 5.2.1


• 使用Quick / QML编写。 / li>
  
• 使用网络模块。


• 使用webkit模块。


• 使用蓝牙模块。 >
  
• QML文件以Quick 2.2编写

解决方案

之后有几个小时在Qt论坛中挖掘，我发现我需要将qml文件夹（通常位于C：/Qt/5.2.1/qml）中复制到应用程序的根目录下。在这样做之后，我的应用程序的动态和静态版本都适用于香草系统。

程序目录MinGW 4.8 32位，动态）：

如 hyde 说，使用 windeployqt 工具（< qt path> \< version> \bin\windeployqt.exe ）将nescesary文件复制到应用程序的文件夹。之后，将所需的QML组件从< qt path> \< version> \qml\ 复制到应用程序的文件夹。生成的文件夹应该类似于：

• 平台（文件夹）


• QtQuick（folder） / li>
  
• QtQuick.2（文件夹）


• 您需要的任何其他QML组件


• app.exe


• icudt51.dll


• icuin51.dll


• icuuc51.dll


• libgcc_s_dw2-1.dll


• libstdc ++ - 6.dll


• libwindthread-1.dll


• Qt5Core.dll


• Qt5Gui.dll


• Qt5Qml.dll


• Qt5Quick。 dll


• Qt5Network.dll


• Qt5Widgets.dll

程序目录（静态）

静态编译应用程序，然后复制所需的QML组件从< qt path> \< version> \qml\ 到应用程序的文件夹。生成的文件夹应该类似于：

• QtQuick（folder）


• QtQuick.2 ）


• 您需要的任何其他QML组件


• app.exe

<我认为崩溃的原因是Qt5Gui.dll（动态和静态）尝试加载QtQuick *文件夹在运行时间，但找不到它们（从而在加载期间崩溃应用程序）。



I've written a couple of applications in QML (part of Qt 5). In a question that I've made before (https://softwareengineering.stackexchange.com/questions/213698/deploying-qt-based-app-on-mac-os-x), I found the solution for deploying my app on OS X (using the macdeployqt tool).

Deploying Qt4 apps on Windows was easy:

1. You compiled it in release mode.
2. You copied the necessary libraries (DLLs).
3. You tested and it worked.

Unfortunately, this approach did not work in Qt5 (I even included the platforms folder with the qwindows.dll file and it did not work). After some days of trying, I gave up and compiled a static version of Qt5.

Again, it did not work. The app works on a PC with Qt installed, but it crashes on "clean" PCs. As a side note, Windows 8/8.1 systems don't give a warning or a message notifying me about the app's crash. But in Windows 7 a message notifies me that the application crashed.

I've tried running Dependency Walker (depends.exe) and all libraries in the static build of my application seemed fine.

In Windows 8, I don't get any error. But after profiling the app in depends.exe, I get an access violation originating from QtGui.dll. The exact error is

Second chance exception 0xC0000005 (Access Violation) occurred in "QT5GUI.DLL" at address 0x61C2C000.

Is there something that I am missing (say an extra DLL or config file)?

Application information:

• Written and compiled with Qt 5.2.1
• Uses Quick/QML.
• Uses the network module.
• Uses the webkit module.
• Uses the bluetooth module.
• The QML files are written in Quick 2.2

解决方案

After some hours digging in the Qt Forums, I found out that I need to copy the "qml" folder (normally located in C:/Qt/5.2.1/qml) to the application's root directory. After doing so, both the dynamic and static versions of my application worked on vanilla systems.

Program directory (MinGW 4.8 32-bit, dynamic):

As hyde said, use the windeployqt tool (<qt path>\<version>\bin\windeployqt.exe) to copy the nescesary files to your application's folder. After that, copy the required QML components from <qt path>\<version>\qml\ to your application's folder. The resulting folder should look similar to:

• platforms (folder)
• QtQuick (folder)
• QtQuick.2 (folder)
• Any other QML components that you need
• app.exe
• icudt51.dll
• icuin51.dll
• icuuc51.dll
• libgcc_s_dw2-1.dll
• libstdc++-6.dll
• libwindthread-1.dll
• Qt5Core.dll
• Qt5Gui.dll
• Qt5Qml.dll
• Qt5Quick.dll
• Qt5Network.dll
• Qt5Widgets.dll

---

Program directory (static)

Compile the application statically, then copy the required QML components from <qt path>\<version>\qml\ to your application's folder. The resulting folder should look similar to:

• QtQuick (folder)
• QtQuick.2 (folder)
• Any other QML components that you need
• app.exe

---

I think the cause for the crash was that the Qt5Gui.dll (dynamic and static) "tried" to load the QtQuick* folders during run time, but could not find them (thus crashing the application during load).
