Did you copy the qwindows.dll as well (needs to be located in a subdirectory "platforms") ?

cislaonch

I haven't "platforms" directory or qwindows.dll file...

Hi!
Look at this link:

This is one reason why I prefer Linux, the finding of dlls is much more sane there.

qxoz

Yes :). But Linux has own problems with deployment if you need run apps whith different versions of libs. Besides not always you can choise target os.

tzander

Linux (and unix) builds versioning of libraries into the basic model, so unless you do something really weird or use non-standard directores, then no, you do not have these issues. Linux also uses rpaths build into the app, making the concept of a PATH not needed for most properly deployed software.

Anyway, just wanted to let people reading a thread like this know that this is a Windows specific problem. Nothing more than just information :)

in windows better to copy "libEGL.dll" from qt bin folder.that will solve your problem.that means copy QTGui, QtCore, QtWidget, libwinphtread, libstdc++6, libGLESv2, libgcc_s_sjlj-1, icuuc49, icuin49,libEGL.dlls.
and copy these in debug or release folder.and make a folder name "platforms" in that add "qwindows.dll" and also add another folder as "imageformats"and add "qgif.dll","qico.dll","qjpeg.dll" and related image dlls.put in a format that platform ,imageformats above dlls(dtgui,QtCore, QtWidget, libwinphtread, libstdc++6, libGLESv2, libgcc_s_sjlj-1, icuuc49, icuin49,libEGL.dlls.) and related exe file in one folder .sso that it will link perfectly i think..
good luck....:)

I have the same issue with Qt5 but i was not able to find the solution.. in the pc i developed the app.exe works ok... but in other pc's not...

clouca

i found the solution... a folder platform with files qwindows.dll and qminimal.dll must be include in the deployment directory..

Hi Guys.

I have the same problem and i have solved it.

Here is how i did it.

I have located a folder C:\Qt\Qt5.0.2\Tools\QtCreator\bin\
Locate your project folder "the project your have created project"
Locate your debug folder and drop the platform folder you have copied from your plugins folder
mine is located at C:\Qt\Qt5.0.2\5.0.2\mingw47_32\plugins (Default)

The platform folder contains the following .dll files
qminimal.dll
qminimald.dll
qwindows.dll
qwindowsd.dll

In a nutshell i have copied the platform folder into my debug project file folder and runs the application without any error message.

clouca is right.

I have try all methods. But I still failed. This problem upset me a lot. I think I have to give up Qt!

Don't forget to remove debug-binaries once you want to roll out the release.

@wutonjie: Start a thread and explain your problem.

Condition:in the pc i developed the app.exe works ok... but in other pc's not, error:This application has requested the runtime to terminate it in an unusual way

This problem appears when the PC disappear some runtime dll , include some of windows,
So check the dll needed by the program, it will help to solve this problem
