@Leonardo Thanks, that helped.
@SGaist Thanks, I'll check that.

What do you mean by "other dependency for qwindows.dll"? I only have that one, in the platforms subfolder. Copying it into the exe folder doesn't change anything...

@danks_
That is good to hear !
Could also been some kind of setup problem with 5_5 but yeah it does
seems like a bug.

I will try with 5_5 and see it it fails for me too.

update:
Tested win pure 5_5 install
It worked by copying the DLLs ! ?
Even worked with no sub sqldrivers folder ...!
(in the release folder)

But when moved out of the virtual machines
it did want the sqldrivers folder to work.

So the current version of 5.5 via the online installer does seems to work in regards to sql.?!

yes that was the problem thanks ^^

@JKSH Actually that's the tutorial I followed! I must have linked the wrong one when I made this post. I had so many tabs open. Thanks for pointing it out!

But yeah. even following it I still have the issue...

EDIT: one my second go round, you were right. I had not copied all the plugin folders from the ming directory. Thank you so much for your help @JKSH

Hi,

Thanks a lot. This finally worked. I have somehow missed this article. Thanks again.

PS: Since I am kind of new here, is there a way to mark an answer as a "solution" or something like that?

@Kraken

No. I did it that way:

1.) Compile against the system's Qt version on the target machine. (ie. install Qt through apt-get system-wide, then use the system Qt to compile).

2.) You can use debreate to guide you through the whole process of creating a deb package. At some point you will have to enter your apps dependencies. To find out what these are, you can use dpkg. (don't exactly remember the commands, dpkg -S and dpkg -s, you need to do some research here. Those will show you the exact version your binary depends on). When you distribute your app via deb, the correct dependencies will be installed on the target machine then.

@vinicius Hi, I solved this by using the cmd
"D:\Qt\Qt5.8.0\5.8\mingw53_32\bin\windeployqt.exe test1.exe"
it automatically copy all the dependent dlls to the folder. some of the dlls are not indicated by the error messages. But it just works

@themts said:

and some from
QTDIR\Tools\QtCreator\bin

Yeah... don't do that ;-)

It's something related to the android sdk used.

On Projects, Build Android APK, change the Android build SDK with another newer.

For example, it gives me the same error and after change it from android-16 to android-21 it works.
