Qt Platform Plugin Windows Update My Blog

As a result, your viewing experience will be diminished, and you may not be able to execute some actions.

I literally have the entirety of my Qt distribution in the deployment directory on my test machine (free of any Qt installations).

This means I have all dlls from.bin, everything from plugins, and everything from qml.

If you try an empty widgets project (like in my blog post) and deploy that, you still get the error.

I tried a simple QML Hello Wold application and that worked just fine.

Try turn on plugin loading trace: (quoting my post): in the Projects mode page, at the bottom, add the environment variable QTDEBUGPLUGINS by clicking Details in Build Environment.

Set the value to 1.

Then Run your project again, and look in Application Output window, youll see lines like QFactoryLoader::QFactoryLoader() checking.

Qt Platform Plugin Windows Update My Blog

Been meaning to check why, if I find why Ill update my blog post).

When I try to run it on my Surface Pro (Windows 8 Pro), I get an error.

I also now got the same error on another machine, running Window 2008 Server.

I then tried to run the app on my Surface - got the error - Googled around - copied the qwindows.dll from my Surfaces Qt installation I know took the qwindows.dll from my dev machine, placed in platforms -folder, and vila, it runs.

In my dev machine, I have two qwindows.dlls in my C:QtQt5.1.1 folder.

Should I always take the DLLs Depency Walkers tells me to, from that folder exactly, not from QtCreator folder.

That means you can run and use it even when you dont have any Qt version or compiler installed on your machine.

So, if you need it just for its Python support, or you are interested in Qt Creator as an IDE for pure C projects, you can still use it.

Also, if you have several Qt installations working in parallel, it is important that Qt Creator itself is in no way affected by them - that is, it should not link to any external Qt, as it would easily lead to numerous errors.

The copies of Qt DLLs you find inside Qt Creator package are not ready to be redistributed, they are there only to make Qt Creator work.

Its the best Ive used so far, although I havent really used Visual Studio yet.

But for now I dont even want to, Qt Creator has everything I need.
