[Solved] More Qt Dll Issues. Cannot find windows plugin in debug mode.

primem0ver

A while ago I posted a discussion on why Qt doesn't implement a way to copy the proper dll files to the build folder. I now understand some of the issues involved now that I have multiple versions of qt installed. However, I still maintain that this could be done for the default configuration.

Regardless,, I am really sick of this shortcoming. I have now run into a problem where I have copied all the necessary files and I cannot even start my application in debug mode. That means I wasn't able to view the list of files I need to copy. Even so, I went one by one through all the the files I needed by restarting my application for each dll I needed to copy.

Now it is telling me that it cannot locate the windows plugin. YES. I have copied that file. I have tried putting it in the application directory, a subdirectory called platforms, and a subdirectory called plugins\platforms. None of these have worked.

FYI I am using the Addin for VS 2012.

Hi, guessing but maybe you copied qwindows.dll, but in debug mode, try instead copying qwindowsd.dll to platforms.
(Also dlls it depends on, like libEGLd.dll...)

i already copied both plus the pdb.

Hmmmm, you mean qwindowsd.dll to platforns, and libEGLd.dll, libGLESv2d.dll, MSVCR110D.DLL, MSVCP110D.DLL etc. together with your .exe file?

That worked. Thanks. (I was missing one of the lib files since it was reported as missing).

Here's a reasonably quick and almost-foolproof way to identify the DLLs you need: http://qt-project.org/wiki/Deploy_an_Application_on_Windows

Also, did you try the windeployqt tool?
