[Solved] Qt 5.0.1 + MSVC2010 desktop app deployment
-
Unless you are linking to the static version of OpenCV you will need to copy the dlls besides your application or have them in your PATH environment variable.
One thing you can to is to check your application with Dependency Walker to see whether you have something missing (which should yield a crash unless it's a plugin not loaded)

Ok, so I copied the OpenCV dlls corresponding to the libs I added to my .pro file to the exe file directory, nothing happens.
Dependency walker shows:
@Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.
@There are a few modules with red-ish icons with names like
@EXT-MS-WIN-ADVAPI32-PSM-APP-L1-1-0.DLL@
is it a problem? What can be the cause?

No, these ones are not a concern.
Can you show a picture or write down how your current application folder looks like ?
e.g
myfolder
myapp.exe
libopencv_core.dll
platforms
….qwindows.dll
plugins
….imageformats
……..qjpeg.dll -

Ok, my app folder looks like this:

!http://images.megaupload.cz/platforms.PNG(platforms folder)!plugins/imageformats:
!http://images.megaupload.cz/imageformats.PNG(imageformats)!To be honest, I copied everything, out of desperation, hoping that I could erase the stuff I do not need later.

Silly question but… Is this in the release build folder ?

Yes, it's in the release build folder.

Which installer of Qt did you use ?
Also, why not update to a more recent version ? Current stable is 5.1.1 and 5.2 is almost out.

Desktop Qt 5.0.1 MSVC2010 32bit. I didn´t keep track of the current versions, but ok, I'll update the Qt and see what happens.

IIRC, it means that it's an ANGLE build, I don't know whether this can play a role when also using OpenCV.
If it doesn't get better, just build a default widget project and try to make it run. Doing so you'll be sure that it can start properly on your computer

OH GOD IT ACTUALLY WORKS!
I built it using Qt 5.1.1 and placed the new version dlls in the release folder and it works! You are my hero! Thanks a million!
