Qt 5.0.2 and Mingw 4.7 deploy

I search to deploy my application. It is used Qt 5.0.2 and Mingw 4.7 as compiler.

I copied all the dll :

  • D3DCompiler_43.dll
  • icudt49.dll
  • icuin49.dll
  • icuuc49.dll
  • libgcc_s_sjlj-1.dll
  • libstdc++-6.dll
  • libwinpthread-1.dll
  • Qt5Core.dll
  • Qt5Gui.dll
  • libGLESv2.dll
  • Qt5Svg.dll
  • Qt5Widgets.dll
  • Qt5Xml.dll

in my folder release.

All this dll are necessary, otherwise I get a message "... .dll manquante".

Now when I launch my exe in the release folder I get the message :

"Microsoft Visual C++ Runtime Library

Runtime Error!

Program: ...\release\test.exe

This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information."

Why this message ?

Qt5 on Windows requires qwindows.dll which should be deployed relative to the main executable like so:

  • {yourAppPath}\YourApp.exe
  • {yourAppPath}\platforms\qwindows.dll

EDIT {yourAppPath}\ is the plugin root directory and so \platforms\ and other plugins should be placed there, and not in {yourAppPath}\plugins as I had originally written.

Assuming that you are using Qt Creator and can launch your application at all try using MS's Process Explorer to discover what Qt DLLs are being loaded by your application.
