Qt部署；过程入口点...找不到 [英] Qt deployment; the procedure entry point ... could not be located
问题描述
我已经移植了一个现有的Qt4应用程序Qt5，并为此应用程序添加了一些额外的（简单的）功能。
I have ported an existing Qt4 application Qt5 and added some extra (simple) functionality to this application.
旧应用程序随附
- libgcc_s_dw2_1.dll
- libusb-1.0.dll
- mingwm10.dll
- QtCore4.dll
- QtCored4.dll
- QtGui.dll
- libgcc_s_dw2_1.dll
- libusb-1.0.dll
- mingwm10.dll
- QtCore4.dll
- QtCored4.dll
- QtGui.dll
现在，从QtCreator我可以运行我的修改的应用程序，但是在准备部署时会出现问题。我在.exe上使用了依赖行者，并且在我的可执行文件目录中包含了DLL的负载。
Now, from QtCreator I am able to run my modified application, but problems occur when preparing deployment. I have used dependancy walker on my .exe and included a load of DLL's in my executables directory.
- icudt51.dll
- icuin51.dll
- icuuc51.dll
- IEShims.dll
- libgcc_s_dw2-1.dll
- libGLESv2.dll
- libstdc ++-6.dll
- libusb-1.0.dll
- libwinpthread-1.dll
- mingwm10.dll
- Qt5Core.dll
- Qt5Cored.dll
- Qt5Gui。 dll
- Qt5Guid.dll
- Qt5Widgets.dll
- Qt5Widgetsd.dll
- QtCored4.dll
- icudt51.dll
- icuin51.dll
- icuuc51.dll
- IEShims.dll
- libgcc_s_dw2-1.dll
- libGLESv2.dll
- libstdc++-6.dll
- libusb-1.0.dll
- libwinpthread-1.dll
- mingwm10.dll
- Qt5Core.dll
- Qt5Cored.dll
- Qt5Gui.dll
- Qt5Guid.dll
- Qt5Widgets.dll
- Qt5Widgetsd.dll
- QtCored4.dll
（是的，由于DLL的存在，项目大小现在非常大，但在我的用例中
(Yes, the project size is now extremely large due to the DLL's, but in my use case this is not an issue.)
最后，它并没有抱怨缺少DLL。尝试执行.exe时发布的错误消息是：
And finally it didn't complain about missing DLL's. The error message posted when trying to execute the .exe is:
过程入口点？testBit @ QBitArray @@ QBE_NH @ Z找不到动态链接库Qt5Core.dll
The procedure entry point ?testBit@QBitArray@@QBE_NH@Z could not be located in the dynamic link library Qt5Core.dll
从来没有尝试过在Qt Creator外部执行Qt应用程序，所以我真的不知道该怎么做。
I have never tried executing a Qt application outside Qt Creator, so I have really no idea what to do.
如果有帮助，请执行以下操作：
在Projects-> qmake build config中：Release->有效的qmake调用
If it helps: Under Projects-> qmake build config : Release -> Effective qmake call I have
qmake.exe D:\Product\test_util.pro -r -spec win32-g++
如果需要更多信息以使内容更清楚，请对此发表评论。
If any more information is required to make anything more clear, please leave a comment about it.
推荐答案
我在Qt 5.4.2上遇到了相同的问题，在对我的代码进行了少许修改以根据OpenGL添加新功能之后。我所做的是使用 Qt窗口的部署工具。
I had the same problem on Qt 5.4.2 after slightly modifying my code to add new functionality depending on OpenGL. What I did was use Qt's Window's Deployment tool.
- 创建一个文件夹并将二进制文件放入其中
- 使用cmd发出以下命令，具体取决于您具有哪个版本的二进制文件：
- windeployqt --release Name_Of_Binary
- windeployqt --debug Name_Of_Binary
根据您使用的Qt Creator版本，您可能必须手动复制lib * .dll到目录。此错误在Qt 5.4.2中不存在，但在较早版本中已存在。
Depending on which version of Qt Creator you have, you might have to manually copy the lib*.dll's to the directory. This bug is not present in Qt 5.4.2 but was present in earlier versions.
