  1. Qt Platform Windows Plugin. The Qt Software Development Kit (SDK) is a cross-platform application framework that is widely used for developing application software with a graphical user interface (GUI). It is a portable cross platform application user interface framework which works on the Windows, Linux and Mac OS X operating systems.

What to Consider. The Qt framework is available under both open source and commercial licenses. This dual-licensing model is based on the principal of quid pro quo – roughly meaning “something for something.”.

Hello,

Qt Platform Plugin Error

I face a fairly common problem, only that mine seems to be even more deeper than anyone's of yet. I've created an application with Qt5, on my desktop machine. I grapped the .exe and all the .dll's required by DebugView. When I try to run it on my Surface Pro (Windows 8 Pro), I get an error:

@This application failed to start because it could not find or load the Qt platform plugin 'windows'@

Now, I've tried everything I've came across:

  • Added folder called 'plarforms' in the directory of the .exe, with dll's:

qwindows.dll
qminimal.dll
qoffscreen.dll

Install Qt Platform Plugin Windows 10

  • Added a folder 'plugins' and placed the platforms -folder there

  • Copied the whole plugins folder (although from my Surface's own Qt install, which is Qt5 also though, just
    a version or two newer) to the application folder

  • Copied libEGL.dll to the application folder

  • Created qt.conf with the lines:

@[Paths]
Libraries=./[email protected]

Also tried Libraries=./platforms

NOTHING seems to work. I also now got the same error on another machine, running Window 2008 Server. I really need a solution for this, can anyone help? :(

I have installed ROS2 Eloquent from the pre-built binary package on Windows 10 v1809. I followed the guide https://index.ros.org/doc/ros2/Instal.

The Talker/Listener example works, however when using:

the program yields 2 warnings:

Install Qt Platform Plugin Windows

Trying out the tutorial https://index.ros.org/doc/ros2/Tutori. and using the turtlesim command:

Found a thread with the same problem, but this solution seems to fix the problem when installing from source and hence installing QT, which is not needed for the binary install? https://answers.ros.org/question/3392.

Finally, trying the 'rqt' command from the same tutorial yields:

I have extra checked the PATH variables from the guide and also added 'C:Python37Libsite-packagesPyQt5Qtpluginsplatforms', but no success.

Any solution to this? Do I need to install QT even though it's not in the guide? Thankful for answers./M

How Do I Install Qt Platform Plugin Windows

I had to install QT to get it to work for me.

Thanks billy, I was able to run turtlesim by doing that. John deere serial number lookup. However, when trying to run the commands where visuals are needed, I think the original problem remains. For example rqt, rqt_graph, rqt_console. Any succes with those?

Oh yes. Same issue for me. Installing QT fixed issue with the turtlebot simulation, but I get same errors trying to run RQT.

Hi marreb and billy, I'm having the same problems. Were you able to find a solution to this?

I fixed RQT_graph somewhat by:

  1. Install windows package from: https://graphviz.gitlab.io/_pages/Dow.
  2. Install python graphviz package
  3. Add C:Program Files (x86)Graphviz2.38bin to User path 4 Add C:Program Files (x86)Graphviz2.38bindot.exe to System Path

However, rqt_graph works poorly and crashes uncontrollably. But you get to visualize your nodes/topics for a limited time =)

Hi guys, have you ever solved this issue about the RosPluginProvider in RQT?

Hi @songyuc, I switched installation method to http://wiki.ros.org/Installation/Windows.

Some fixes to that install can be seen here: https://answers.ros.org/question/3478.

However, you can run rqt with with binary install if you do the fixes in earlier comments, ignore the RosPluginProvider errors.

Qt Platform Plugin Fix

This Application Failed To Start Qt

Hi @marreb, I think this issue may be relevant to the Graphviz, and I installed the Graphviz based on your previous solution. Then the errors about the Graphviz disappear.

  • Install Android Studio with SDK and NDK API Level 28.
  • Install strawberry-perl-5.26.2.1-64bit.msi first (before mingw-w64-install.exe) to E:PFiles
  • Install MinGW with mingw-w64-install.exe online installer. Select POSIX threads in the installer UI combobox, otherwise you will get:
  • Extract the sources from QT archive qt-everywhere-src-5.15.0.zip to E:QtQt5.15.0 and run the following script in QT root directory containing configure.bat:

this script uses NDK 21.2.6472646, but Qt Creator 4.12.1 installs NDK 21.1.6352462:

Building QT application

On my machine the above script built QT successfully, but when I tried to build my app in QT Creator I got:

and when I started rcc.exe manually I got:

Obviously, it requires MinGW to be in PATH:

So I updated Path environment variable in QT Creator:

and the build succeeded and the application started successfully.

Also a possible solution is to copy MinGW dlls:

to QT binary directory.

Testing the app

I tested the app with Android 10 x86 emulators and it seems it is OK, but it is not clear how to test it on ARM because I have ARM images till API 25 only:

Uploading the app to Google Play

When I published the app in Google Play for internal testing it passed the monkey test on all the devices except Android 5.0 armeabi-v7a, see Prelaunch Report:

This crash stably repeated in 3 releases, see below for more information on it:

Modules we build (see generated Makefile at QT root directory):

Notes

I have an impression that using

instead of

results in unstable behavior of the build script.
