[Solved] Exe file does not run without QtCreator (Qt 5.0.1 and QtQuick 2.0)

You have to copy dlls of every module that you used in your project including : QtCore module, QTGui module, ICU, QtQuick, ....

sierdzio

ICU does not keep binary compatibility. Maybe the MinGW package was built with a different version and the linker entries are invalid?

Anyway, you probably also need to copy the platform plugin to plugins/platforms/qwindows.dll.

Now I have so list of dll:

Qt5Core.dll
icuin49.dll
libgcc_s_sjlj-1.dll
libwinpthread-1.dll
libGLESv2.dll
libstdc++-6.dll
qminimal.dll
Qt5Gui.dll
Qt5Network.dll
Qt5Qml.dll
Qt5Quick.dll
Qt5V8.dll
qwindows.dll

But program has problems with run yet. Dependency walker shows that the error that I described:

_ZN6icu_4910CharString15getAppendBufferEiiRiR10UErrorCode

When I copy all dll from C:\Qt\Qt5.0.1\5.0.1\mingw47_32\bin and from C:\Qt\Qt5.0.1\5.0.1\mingw47_32\plugins\platforms programs run, but nothing shows.

Platform plugin needs to be in plugins/platform folder or something similar. Please check that. You can also check system messages or hook your app to terminal to see what the output is. If Qt can't find the plugin, it will shout in cerr.

I copy qwindows.dll and qminimal.dll in folder with program. And these libraries are located in the folder
C:\Qt\Qt5.0.1\5.0.1\mingw47_32\plugins\platforms

But program does not work. With dll from list program shows error _ZN6icu_4910CharString15getAppendBufferEiiRiR10UErrorCode. With all dll from C:\Qt\Qt5.0.1\5.0.1\mingw47_32\bin and from C:\Qt\Qt5.0.1\5.0.1\mingw47_32\plugins\platforms programs run, but nothing shows.

I put the Qt 5.0.1 for Windows 32-bit (MinGW 4.7, 823 MB) on another computer and it has also created an Qt Quick 2.0 application. And the problem is the same.

Yes, that is why I keep telling you it is wrong :) Copy it to <your app>/plugins/platforms.

The error might come from ICU if was compiled with MSVC and MinGW linker points to wrong sections of the library.

Thank you so much! This is what was needed. And I forgot to add the folder with qml files.

I'm having a same problem. I've read what you gays talked and compose the directories like below. But, still, I got this error message when I try to run my application without Qt Creator.

The procedure entry point _ZNKSt9exception4whatEv not found in library DLL libstdc++-6.dll

Please, check my directories and tell me what I have to do more.

/myApp.exe
/libgcc_s_dw2-1.dll
/libstdc++-6.dll
/libwinpthread-1.dll
/Qt5Core.dll
/Qt5Gui.dll
/Qt5Network.dll
/Qt5Widgets.dll
/plugins/platform/qwindows.dll
/plugins/platform/qminimal.dll

[quote author="yckim" date="1390135860"]The procedure entry point _ZNKSt9exception4whatEv not found in library DLL libstdc++-6.dll[/quote]That means you are using the wrong versions of the MinGW DLLs. Where did you get them from?

[quote author="yckim" date="1390135860"]/plugins/platform/qwindows.dll

/plugins/platform/qminimal.dll[/quote]

Remove the "plugins" layer.

It's "platforms", not "platform"

You only need qwindows.dll, not qminimal.dll

It should be /platforms/qwindows.dll

You are right. I just figured out that there are two libstdc++-6.dll on my computer. One is under \MinGW\bin(what caused the problem). The other one is under \Qt\Qt5.2.0\5.2.0\mingw48_32\bin, and it works fine!! Thanks.
